New Optical Grade Adhesives


Panacol-USA will feature new optical grade resins and adhesives for imprint and optical bonding applications at the SPIE Photonics West exhibition in San Francisco CA, USA from 30 January to 1 February 2024. These new adhesives can be used for light carpets in the automotive industry, for sensors in smart devices and wearables, or for creating structured light in projectors or time-of-flight sensing applications.

Panacol specially formulated adhesives for imprint replication of refractive lenses and diffractive optical elements (DOEs). These adhesives are suitable for micro- and nano-imprint lithography, wafer level optics, and wafer bonding. The newly introduced adhesives Vitralit® UC 1632 and Vitralit® UC 1658 are in the viscosity range of 100 to 200 mPas and can thus be easily applied via puddle dispensing, spin-coating or jetting. They offer excellent adhesion to commonly used grades of glass wafers and upcoming new polymer substrates including optical grade PET or PC. Once applied and imprinted, the adhesives are quickly cured with UV light, creating a precise and durable structure on the wafer. Both adhesives are tailored specifically to meet the high demands of optical reliability, such as low yellowing, temperature stability, and shape retention.

For black shading and masking purposes, Panacol also offers a black UV curable adhesive, Vitralit® BL UC 1103. This black epoxy adhesive is permeable to UV light while uncured.  After curing it is opaque and light blocking.

For optical bonding and alignment, Panacol has developed UV curable adhesives Vitralit® 7311, Vitralit® VBB-60, and Vitralit® 1860, as well as heat curable adhesives Structalit® 5531 and Structalit® 5511. These adhesives feature high adhesion to glass and widely used plastic substrates. Adhesive Vitralit® UD 8057 is formulated for dual curing using UV/visible light and atmospheric moisture. This allows the adhesive to complete its curing using moisture in shaded areas that cannot be reached with UV/visible light.

These adhesives for optical bonding get easily cured with high intense LED curing systems of Hönle, which perfectly match the wavelengths of the Panacol photoinitiators. Once cured, Panacol’s optical grade adhesives are flexible and tension equalizing, reducing the stress on dissimilar substrates.

New Adhesives for Flexible Photovoltaics and Electronic Applications


Organic photovoltaics (OPV) and Perovskite-based systems are creating radically new applications in consumer electronics. They include indoor light harvesting to extend battery life of wearables, and outdoor energy generation with performance in regard of their flexibility previously unimaginable from conventional photovoltaics. The same is true for flexible electronics. A key contributor to these advancements has come from progress in bonding technologies. Panacol accompanies these developments by providing high tech adhesives that elevate flexible photovoltaics to the next level.

Today’s adhesives go beyond the basic benefits of sound structural bonding by providing additional functionality to the assembly. Panacol has successfully developed a range of multi-functional adhesive selections for applications in flexible photovoltaics and electronics. For OPV applications, these adhesives provide higher resistance to environmental stresses, an improved compatibility to the PV material and a good adhesion to the substrates. New conductive adhesives efficiently adhere and protect electrical connections for SMD components in flexible assemblies.

In all cases, the specific requirements of the application and its assembly process are key factors to consider when making an adhesive selection. Significant benefits can be realized when an optimal pairing is achieved with the component design, assembly, (UV) adhesive properties, and the curing process. High throughput processes, including roll-to-roll can be run with greater efficiency which reduces total cost of operation. The adhesives requirements such as flow properties can be modified in this context to suit the application process perfectly.

As new designs are evolving rapidly, very little standardization exists in the manufacturing of OPV. To support this evolution, adhesives must be modified or developed to meet the customers’ unique OPV design, materials, and processes.  Panacol has anticipated this need and is prepared to work with manufacturers to provide adhesive customization and development as quickly as possible.

Special Adhesives for Medical Wearables


Wearable patient monitoring devices are worn directly on the body and are being used in increasing numbers. These devices include diabetes sensors for monitoring blood glucose levels (GCM), as well as wireless monitors that transmit patient information to healthcare providers. They must be reliable and durable, while also safe for direct skin contact. Panacol has developed a broad portfolio of specialty adhesives for this purpose that meet the stringent demands imposed by medical device manufacturers. To be able to provide a complete bonding solution, Panacol teamed with metering equipment manufacturer Scheugenpflug and UV equipment manufacturer Dr. Hönle.  A system concept was identified and successfully tested that enables precise metering for the dispensing of low volumes of UV adhesives with integrated LED UV curing.

Panacol’s medical device adhesives exhibit excellent adhesion to commonly used medical-grade substrates, including polycarbonate, polyimides, polyamides, stainless steel and ceramic. These adhesives are tested for biocompatibility in accordance with ISO 10993-4/-5/-10/-23 and/or USP Class VI protocols.

This group of adhesives includes LED curable UV acrylates and UV epoxies which provide the shortest curing cycle times for high volume production.  They are ideal for needle/hub assembly, component attachment, and for sealing enclosures.  Multiple viscosity ranges are available to provide the best match to component configuration and assembly process.  Fluorescing versions are available to enhance quality control relying on in-line vision systems.  

Also included in this group are electrically conductive adhesives and conventional thermosetting epoxies.  They offer connectivity and attachment solutions for PCB and electrical component assembly. Several epoxy selections are available with high ionic purity which is essential to minimize the risk of corrosion on the PCB.  Panacol’s silver-filled electrically conductive adhesives can often replace solder joints or be applied on bendable or flexible wearables.

Accurate and consistent adhesive dispensing is mandatory when assembling medical devices. For the small dispensing volumes, the best choice is the high-precision DosPL DPL2001 micro dispensing head from Scheugenpflug, part of the Atlas Copco Group. This allows highly accurate application of the adhesives even for the smallest volumes down to the µl range. This allows glob tops to be reliably set to 0.003ml, dispensing accuracies of less than 0.5% to be achieved, and the thinnest lines to be made on the plastic housing with precise start and stop.
The dispensing head works on the principle of volumetric dispensing. A control system reliably detects viscosity fluctuations and ensures consistently high precision of the bonding contour.

The curing or hardening of Panacol’s UV acrylate and epoxy adhesives can be achieved in seconds due to their uniquely formulated compositions.  LED curing systems from industry leader Dr. Hönle enable maximum optimization of the curing process.  This ensures the shortest curing cycle time and the highest thruput.  In the tested system concept, Hönle's LED Spot 40 IC, with a wavelength of 405nm was used. The compact design of this LED head allowed it to be integrated with the DosPL DPL2001 dispensing head into Scheugenpflug’s DispensingCell DC803 multifunction robotic cell. This work cell permits components to remain in one position for both dispensing and UV curing processes. Parts handling is minimized,  along with the risks of  component movement, contamination, and adhesive migration.  This integrated system concept ensures the adhesive bonding process is performed to the highest quality standards with the greatest efficiency.   Whether batch production or continuous flow, integrated adhesive bonding systems from Panacol, Scheugenpflug, and Hönle meet the demanding production requirements for medical wearables.

Fast-curing SMD adhesive for precise dispensing


New Structalit® 5604 is an extremely fast-curing adhesive which is specifically developed for bonding SMDs to printed circuit boards. The adhesive is based on epoxy resin and is, despite its high viscosity, suitable for jet application.

Structalit® 5604 is a one-component epoxy resin adhesive that contrasts well with green PCB material due to its red color. This makes it possible to ensure visual inline inspection. The one-component adhesive can be dispensed in production through jetting, valve dispensing or screen printing. Its ideally adjusted viscosity and high thixotropy index enable high-speed dispensing, precise dot profiles, and non-slumping wet adhesion prior to curing. 

This adhesive is cured with heat. The thermal cure occurs within minutes, even at low temperatures. When fully cured, the adhesive is extremely temperature resistant. It can withstand short-term temperatures of up to 270°C, making it suitable for reflow soldering processes.

Structalit® 5604 is particularly shock-resistant and durably adheres to FR4 printed circuit boards, metals, and epoxy-based molded materials. Due to its high glass transition range of >115°C, the adhesive is ideal for electronic component assembly. It does not lose adhesion or softens at elevated temperatures. As Structalit® 5604 was developed specifically for use in electronics, it has high ionic purity and thus provides optimum protection against internal corrosion.

New dual-curing UV acrylic adhesives with high Tg

With the introduction of Vitralit® UD 8055 and Vitralit® UD 8056, Panacol continues to expand its portfolio of dual-curing acrylic adhesive systems. These adhesives principally cure with UV light. They also possess a secondary moisture post-cure mechanism to compensate for shadowed areas. A special characteristic of these two adhesive systems is their high glass transition range of over 100°C, which helps to preserve high-strength bonds through thermal cycling stress.

The two adhesives are ideal for use as encapsulants that provide environmental protection to sensors and PCB components. They can also be used for bonding dissimilar substrates including many plastics and metals where undercuts or geometry-related cavities are present. This is precisely where they demonstrate their dual-cure advantage. The secondary moisture cure mechanism overcomes the challenge of shadowed bond lines and ensures a reliable bonding process. 

In the primary UV curing process, the bonded areas in the component are fixtured in seconds by UV light. LED curing systems can be used possessing wavelengths of 365 or 405nm. LED systems do not require any warm-up phases and thus enable the shortest cycle times. LED and UV pioneer Dr. Hönle offers a broad selection of spot and flood-style systems that are optimally matched to Panacol's adhesives and can be individually adapted to the application requirements.

In the secondary post-curing process, uncured monomers crosslink in shadowed areas by atmospheric moisture without stress and the need for secondary thermal exposure. This technology enables fast cycle times and high-volume production without subjecting temperature-sensitive electronics or components to excessive thermal stress.

A high glass transition range is particularly important when encapsulations and bonded substrates must withstand thermal stress over long periods of time. Exceeding 100°C, the Tg of Vitralit® UD 8055 and Vitralit® UD 8056 ensures that thermal expansion coefficients behave homogeneously in the application area. This prevents the adhesive from losing bond strength and creating excessive stress between components which can lead to delamination or cracking in the electronics. Vitralit® UD 8055 and Vitralit® UD 8056 were primarily developed for the production of sensors, PCBs and flex PCBs that are used in consumer and automotive electronics. These components are usually designed for use up to 100°C, making acrylate systems with a Tg above 100°C the ideal solution for such applications. 

Vitralit® UD 8055 and Vitralit® UD 8056  achieve high adhesion with typical substrates such as FR4, PC and PBT.  Vitralit® UD 8055 has demonstrated very reliable adhesive performance through challenging 85/85 aging tests. Vitralit® UD 8056 is particularly impressive for its performance on LCP and has passed UL94 HB tests. With depth of cure that exceeds several millimeters, these two low-halogen adhesives can be used in a wide range of electronic assembly applications.

Black&Light: Black epoxies now cure with uv light only

With their new "Black&Light" adhesive line, Panacol has developed a new adhesive technology: deep curing black epoxies. Black epoxy adhesives from Panacol's Vitralit® product range can now be cured with UV light sources in thicker layers, without resorting to a secondary curing mechanism.

Usually, black UV adhesives have a major disadvantage: their black color absorbs a high proportion of the UV light, which means that the light energy needed to fully polymerize an adhesive can only penetrate a few micrometers. This results in surface “skin” formation on black adhesives, but not a complete cure. These black adhesives must then be cured in a secondary thermal curing process at temperatures above 100°C. 

Panacol's new "Black&Light" technology enables the complete curing of black epoxy adhesives with LED UV energy.  Depth of cure can range from a few hundred micrometers to several millimeters. The adhesives are suitable for encapsulation, glob top, or edge bonding in electronics manufacturing, as well as for optical adhesive systems where high OD values (optical density) are required.  They are suitable for optoelectronic applications to help minimize reflections and enhance sensor transmission values.

A typical manufacturing process using "Black&Light" technology can be as follows: The black adhesive is dispensed and cured with the appropriate wavelength and intensity. During the curing process, the “Black&Light” technology within the adhesive enables the UV rays to penetrate and complete a full cure.  Once the  adhesive polymerization is complete, the structure of the "Black&Light" technology prohibits light transmission, resulting in a fully cured adhesive system that remains irreversibly black.

The "Black&Light" technology is compatible with many Vitralit® epoxy adhesives from Panacol.  Custom adhesive solutions can be created to accommodate unique requirements for amount of light blocking and depth of cure.  The "Black&Light" adhesive systems can be very specifically adapted to specifications of the respective application. 

Another major advantage of the "Black&Light" adhesives is storage. Many single-component, black epoxies require deep frozen transportation and storage. The "Black&Light" epoxy adhesives can be stored and shipped at room temperature or under normal refrigeration.

New UV anaerobic adhesive from Panacol 

Panacol has developed Vitralit® UD 4292 F, a new dual-curing adhesive that cures primarily by UV light with a secondary anerobic cure for shadowed areas. The special feature of this adhesive system is the high glass transition range of >130°C when cured under optimum conditions.

In response to a growing market demand for UV anerobic adhesive systems, Panacol has expanded its portfolio of dual-curing adhesive systems with Vitralit® UD 4292 F.  This new product is ideally suited for structural bonding and sealing in automotive and electronics applications. 

Vitralit® UD 4292 F is a transparent acrylic adhesive that cures in just a few seconds with light in the UVA or visible range.  LED curing devices from Dr. Hönle provide light curing energy in wavelengths and intensity that optimize absorption by the adhesive’s photoinitiators for highly efficient UV light curing cycles. In shadowed areas, this adhesive reacts with metal ions in the absence of oxygen to ensure full cure.  The secondary anerobic curing can be accelerated by adding heat or by applying a chemical activator to one of the surfaces to be bonded. When properly cured, Vitralit® UD 4292 F exhibits very high pull-out forces on various metals. 

These properties make Vitralit® UD 4292 F particularly desireable for a wide variety of electric motor assembly applications, including structural bonding of ball bearings or shaft-hub connections on rotors and stators.  The high glass transition temperature of over 130°C  ensures that the adhesive system retains its bond strength under temperature fluctuations and dynamic stress. This UV anaerobic adhesive system meets the demanding assembly requirements in the electric motor and electric vehicle (EV) markets.

For visual process control, the composition of Vitralit® UD 4292 F contains a fluorescent marker that glows bright blue when exposed to low intensity UV light, making it visible in very thin gaps.

Panacol introduces new line of masking materials

Panacol has developed new UV curable masking materials for industrial processes. These masking materials are part of the Vitralit® MASK product line.  They can be easily applied, cured in seconds by exposure to UV light, and then removed by a simple peel, or for those masks with higher adhesion, hot water dip and peel.

UV mask material is typically used in high value component fabrication that involves processes for surface enhancement.  These processes may include acid cleaning, grit blasting, or shot peening. Component surfaces or internal cavities may need to be insulated from these processes for reasons of functionality. Masking materials are applied as temporary barriers, that are subsequently removed from the completed component after processing. Typical applications include the manufacture of turbine components, orthopedic devices or prosthesis, and other industrial component processes such as the coating of circuit boards and plastics.

The UV masking material is derived from light curable adhesive technology. Panacol’s family of UV light curable mask materials are solvent-free and can be easily applied and cured in seconds with a UV light source. The curing system may be broad spectrum UV or LED in in wavelengths of 365 or 405nm.The uncured liquid mask can be applied on components by syringe, dip, or spray. The masks are available in many viscosities to accommodate a wide variety of component configurations and applications. Both high and low viscosity masks from Panacol can be easily dispensed through spray valves onto larger surfaces. All Vitralit® MASK materials provide uniform and consistent protection from high impact particulates, hot acids, alkali solutions, plating, and paint. Vitralit® UV masks are available in green color to provide higher contrast for better visual inspection.

Removal of Panacol UV mask materials such as Vitralit® MASK 20107 or 20109 is accomplished by a simple peel, or a hot water dip and peel. A selection of Panacol UV masks, such as the new Vitralit® MASK 20116, have extremely high surface adhesion for the most rigorous processing.  These UV masks are best removed through incineration. Panacol UV masking materials do not leave surface residue after peeling or incineration.

New reworkable edge bonding adhesive 

The newly developed Structalit® 5705 is a removable edge bonder specifically formulated for bonding consumer electronics components. In addition to reworkability, the main feature of the black adhesive is that it fluoresces yellow when excited by UV light. This significantly enhances the accuracy of in-line optical inspection systems.

Edge bonding adhesives are used to quickly secure electronic components to printed circuit boards. This fastening method offers superior protection from shock, vibration, and thermal stress.  As a constructive alternative to underfill processes, edge bonding increases the impact and bending strength of BGAs and other chip packages. Edge bonding can also be preferable to underfills when flux residues are present on PCB and component surfaces. 

Structalit® 5705 is a black, thermosetting epoxy resin adhesive that is characterized by its viscous flow properties and high thixotropy index.  These properties enable precise placement of the adhesive with no subsequent migration.  Structalit® 5705 may be dispensed using pneumatic valves, or through highly efficient, contactless jet dispense systems.  This epoxy resin-based edge bonder is low in halogens, and is ideal for electronic components assembly. 

A typical feature of PCB adhesives is a black coloring that is used for light blocking and concealment.  Visual inspection of edge bond placement is commonly performed by manufacturers using in-line camera systems.  Dark-colored, low contrast chips often present difficulties for precise optical measurement. Panacol solves this problem by incorporating a yellow fluorescence into the black Structalit® 5705. The fluorescence is excited by short wavelength light, for instance 365nm. The highly contrasting fluorescence makes it easier for manufacturers to perform in-line inspections, resulting in faster parts processing and increased throughput.

For manufacturers of electronic components, a new challenge is becoming increasingly important.  Global environmental associations are successfully lobbying for legislation to minimize electronic waste.  A critical step in this sustainable strategy is the ability to rework and repair individual modules on printed circuit boards.  Reworkability and repair reduces the amount of electronic component scrap that must be disposed into the environment.  Structalit® 5705 from Panacol provides a reworkability feature. The adhesive can be removed without damaging the bonded components.  This enables faulty components to be removed, and repaired after assembly.

Structalit® 5705 edge bonding adhesive is selectively reworkable when the cured adhesive receives thermal exposure above its glass transition temperature (Tg) of 150°C.  The adhesive softens, and can be manually scraped away using a small spatula or similar instrument. It is only above this critical temperature threshold that the product becomes workable.  Below this temperature, Structalit® 5705 protects bonded components with reliable bond strength and consistent performance.  

Another pressing need for the reworkability of bonded components stems from the current global supply chain parts shortages. Automotive and consumer electronics sectors are experiencing massive production delays, primarily from a shortage of integrated circuits (chips) and electronic board components. The ability to rework components can help to mitigate some of these shortages. Reusing components not only offers advantages for the environment, but has also become essential for maintaining current production processes caused by supply chain bottlenecks.

Structalit® 5705 edge bonding adhesive can be used in conjunction with Panacol’s reworkable underfill, Structalit® 5751. Both adhesives can be applied wet-on-wet and cured together in just one oven process step. The reworkability of both adhesives provides manufacturers with the means to repair components after assembly, and reduce electronic waste.

New epoxy potting adhesive offers maximum protection 

Structalit® 5801 is a black adhesive system that demonstrates exceptional chemical and moisture resistance after accelerated aging. This resistance makes Structalit® 5801 an ideal material for the structural bonding and potting of electronic components that require the highest level of environmental protection. 

Structalit® 5801 is a 2-component epoxy adhesive system with a simple 2:1 mixing ratio.  Curing takes place within 12 hours at room temperature. For faster processing, this black adhesive can also be cured thermally, in as little as 30 minutes at a moderate temperature of 80°C. Lower temperature curing minimizes thermal stress on components, and the shorter cycle time improves productivity. This medium-viscosity adhesive blend has excellent adhesion to metals including aluminum and stainless steel.  It is well suited for the structural bonding of metal frames and housings.  Structalit® 5801 also exhibits very good adhesion to plastics, such as PA6 GF or PBT.  This multi-substrate adhesion allows Structalit® 5801  to be used for many material combinations typically found in the consumer and automotive electronics industries.

This newly developed adhesive cures with low shrinkage, and exhibits good vibration and shock resistance due to its high bond strength and unitizing properties. During aging tests at temperatures above 130°C, Structalit® 5801 actually gains bond strength.  Adhesive exposure to transmission oil, biodiesel, and alcohol during aging resulted in minimal loss of bond strength. This is mainly due to the high degree of crosslinking and the low moisture absorption of this adhesive.

Structalit® 5801 can be dispensed from a 50 ml dual-chamber cartridge which is ideal for manual, short-run, or semi-automated production. This epoxy system is also available in sedimentation-stable bulk containers which can be used with meter-mix equipment for high volume production.

New Flexible Conductive Epoxy 

Elecolit® 3647 is a new addition to our extensive portfolio of electrically conductive epoxy systems. With a history of demonstrated success, this silver-filled conductive adhesive is particularly suitable for bonding with temperature-sensitive films or flex PCBs.

Elecolit® 3647 is a one-component, silver-filled conductive adhesive that adheres very well to plastics, including polyimide, PC, PVC, ABS, and FR4 board. When fully cured, the adhesive is very flexible with high peel strength, making it the perfect choice for use in applications subject to vibration, oscillation or rapid temperature changes. Elecolit® 3647 can be used for die attach applications and component assembly on flexible films and printed circuit boards. This conductive adhesive has utilization in printed and “in-molded” electronics, wearables, and the conductive attachment of semiconductor chips.

A major advantage of Elecolit® 3647 is it’s very easy handling and storage. The adhesive only needs to be stored refrigerated, not frozen! The single-component adhesive can be dispensed, and cures within minutes at temperatures as low as 100°C. This makes it possible to fixture semiconductors and create electrical connections in a single step.

New epoxy adhesive for bonding magnets

Panacol's new adhesive Structalit® 5858 is a modified, one-component epoxy resin adhesive that was developed specifically for bonding magnets into electric motors. Its high bond strength and impact resistance ensures reliable bonding.

Structalit® 5858 can be cured thermally in a conventional oven at temperatures from 100°C. It is also possible to use induction curing for faster polymerization and shorter curing cycles. The adhesive requires storage between 0-10°C, but its stable viscosity and reactivity allow it to be processed on the line at ambient temperature for up to seven days.

The Structalit® 5858 was developed by Panacol to expand its line of adhesives for electric motor assembly.  After proper curing, Structalit® 5858 generates excellent adhesion to metals. With bond strength over 34 MPa on steel and aluminum, this adhesive creates reliable and high-strength bonds.  Even at temperatures above 100°C, Structalit® 5858 continues to exhibit excellent superior bond strength, ensuring consistent performance during thermal stress. The high impact strength of this modified epoxy ensures that bonded components will not loosen or separate from operational vibration or external forces. Structalit® 5858 is particularly suitable for bonding magnets, such as the connection of half-shell magnets in stators, or permanent magnets on rotors.

New biocompatible UV adhesive for soft plastics

Panacol has developed a new plastic bonder that is certified to USP Class VI biocompatibility standards for medical device assembly applications. Vitralit® UV 7030 features high elongation at break, excellent adhesion to difficult-to-bond plastics, and rapid curing under UV light.

The various material selections and pairings of flexible tubing and rigid connectors often create significant assembly challenges in high volume production.  Materials used to create infusion lines, catheters, and similar medical devices may include TPU, TPE, PEN, polyamides, Pebax®, polycarbonate, ABS and PEEK. These thermoplastics and thermoplastic elastomers provide many desirable properties, but some combinations can be difficult to bond. After assembly, these materials are challenged by torsional stresses at the points of transition between the soft tubing and the hard connector.  Panacol developed the adhesive Vitralit® UV 7030 to specifically address these complex issues.

Vitralit® UV 7030 is a one-component, solvent-free UV curable acrylic adhesive.  It can be cured with light energy in the broad UV-A spectrum, or with LED systems that produce either 365 or 405 nm wavelength. This adhesive cures in seconds at layer thicknesses of a few 100 µm, ensuring high bond strength immediately after UV exposure. A key feature of Vitralit® UV 7030 is its high elongation at break, >250%, combined with good tensile strength. When exposed to black light, Vitralit® UV 7030 fluoresces, which enables visual process control. Vitralit® UV 7030 is certified to USP Class VI standards and suitable for typical sterilization processes including gamma, EtO and autoclave.

Panacol introduces new reworkable underfill adhesive

Panacol has developed a new reworkable underfill for consumer electronics. The reworkability and fluorescence despite its black color of the new Structalit® 5751 adhesive allows manufacturers to reduce both manufacturing costs and environmental impact by reusing electronic components mounted on PCBs.

Underfills serve the purpose of equalizing stresses between chip and substrate. Chips are attached directly to the interconnection points without intermediate elements. Stresses arise at the solder bumps when the electronic modules are heated and cooled during operation due to the different coefficients of thermal expansion of the substrates. Underfill technology was developed to counteract these mechanical influences.

Structalit® 5751 is a black, heat-curing, resin-based epoxy adhesive characterized by its low viscosity and linear flow behavior. These properties enable precise application. In addition to classic contact dispensing by means of a dispenser, the uncured properties of Structalit® 5751 also allow contactless dispensing for fast and precise placement of the adhesive. This underfill is has a low ion content and is ideally suited for electronic component packaging.

A typical feature of adhesives on PCBs is their black coloring, which is used to obscure proprietary features and for optical inspection. Optical measurement of an underfill is a common method used in the manufacturing process by manufacturers. But due to the dark chip, shallow layer thickness of the black adhesive and tight gap between the chip and the substrate, optical measurement is often difficult. Panacol has addressed this problem by incorporating an additional yellow shimmering fluorescence to the black coloration of Structalit® 5751. It can be stimulated by short wavelength light of <365nm. This makes it even easier for manufacturers to perform final inspections and speeds up production processes.

In addition to the performance and optical inspection capability of Structalit® 5751, Panacol offers another important property with its newly developed underfill: reworkability. This provides the ability to re-process or repair products after assembly. For manufacturers of electronic components, this challenge is becoming increasingly important as legislation and environmental associations push for the minimization of electronic waste. One starting point of this sustainable strategy is the reworkability and repairability of individual modules on printed circuit boards to counteract the scrapping of a complete component or module.

Structalit® 5751 can be strategically softened at specific adhesion points by applying temperatures above its glass transition temperature range of 150°C. The product becomes reworkable only when this critical temperature threshold is reached.  The reworkability temperature does not reduce the protective function of the Structalit® 5751 during typical PCB processing.  It withstands temperatures associated with reflow soldering and additional thermal curing cycles.

The current global shortage of chips and general electronic components in the automotive and consumer electronics sectors further highlights the significance of being able to reuse components.  Reuse of components is not only a benefit to the environment, it has become essential to sustain current production processes due to supply chain shortages.

New epoxies from Panacol-USA cure at 60°C

Panacol has developed a range of new one component epoxy adhesives that cure at very low temperatures. These new adhesives were developed specifically for electronics applications and adhere very well to substrates with low surface energy.

With the adhesives Structalit® 5511, 5521 and 5531, a range of adhesives has been developed that exhibit a unique set of physical properties after reaching full cure. This permits optimizing the adhesive with various component geometries, substrates, and operating functions.  

All three adhesives are single-component, epoxy resin-based adhesives and cure at just 60°C, making them particularly suitable for temperature-sensitive electronic components. Curing at higher temperatures will accelerate cure time and add additional strength to the bond. 

The Structalit® 5511 adhesive features a particularly low ionic content and is therefore especially suitable for use in electronics. Combining a high Young's modulus with an elongation at break of more than 8%, it ensures high adhesion to many substrates with additional shock and vibration resistance.

Structalit® 5521 is softer and more flexible after curing, allowing the adhesive to better compensate for stresses between substrates. Due to its very low modulus of elasticity, this adhesive is very well suited for potting or for the application of thicker adhesive layers.

As the third adhesive of the new epoxy technology, Structalit® 5531 has an extraordinary low coefficient of thermal expansion (CTE), yet is flexible enough to withstand drop and vibration tests. The incorporation of filler particles gives the adhesive extremely high resistance to mechanical and chemical influences.  

These Structalit® adhesives from Panacol generate very high bond strength with materials typically used in the electronics industry. They can also adhere very well to LCP (liquid crystal polymer) and other high-tech plastics with low surface energy. All three adhesives possess high purity and low ion content which complies with international standards for electronic and microelectronic component assembly.

New high-performance frame-and-fill adhesives

A new range of high-performance adhesives for frame-and-fill applications on printed circuit boards is now available at Panacol-USA.

Frame-and-fill processes are used to protect highly complex areas on electronic circuit boards. In the first step, a highly viscous barrier – the so-called frame – is applied. In the next step, this area is quickly filled with lower viscosity filler material – the fill. With this precise process, areas on the circuit board can be protected from mechanical impact factors. The combination of frame-and-fill materials allows the application of minimum barrier and potting heights and cures to a homogeneous coating. Panacol's new frame-and-fill adhesives are perfectly matched so that the frame and fill areas can be optimally dispensed wet-on-wet without the still-liquid adhesives leading to undesired flowing on the PCB.

The frame material, Structalit® 5704, is a black, thermally curable and single-component epoxy. This frame and glob top compound features excellent bead stability and high glass transition temperature of 150°C up to 190°C, depending on the curing parameters and the layer thicknesses. When using Structalit® 5704, no bleeding effects occur. Due to the very low ion content of less than 20 ppm, Structalit® 5704 is suitable for chip encapsulation on electronic circuit boards. 

As a fill material, Panacol has developed a range of adhesives with different rheological properties. The adhesives Structalit® 5717 to Structalit® 5721 are formulated with optimized flow behavior, so that the adhesives can be used on various chip and bonding wire geometries due to the differently adjusted viscosities. Since the fills have the same chemical base as the frame material, the excellent physical and chemical properties of high glass transition range, ion purity, temperature stability and minimal shrinkage behavior are also found in the fillls. 

Once cured, Structalit® 5704 and the matching fill of the Structalit® 5717-5721 series form a black, opaque and scratch-resistant coating. These properties together with a temperature resistance of up to 200°C ensure maximum reliability.

Smart system solution for needle bonding

A main field of application for adhesives in medical systems is needle bonding and syringe assembly in high volume production. Optimally matched processes are essential for reliable bonding. Panacol, Hönle and bdtronic partner to ensure that precise adhesive dosing, capillary flow and curing in seconds with UV light work hand in hand.

As the needles are produced in large quantities rapid and reliable bonding is essential. In addition to their mechanical bond strength, the adhesives used must allow high-precision production and permanent joining and must withstand various sterilization methods. Panacol’s UV curable Vitralit® adhesives exactly meet these requirements.  Vitralit® adhesives are available in various viscosity ranges to perfectly fit the design of the needle hub and fill the gap between the hub and the needle. The material of the hub and needle also affects the choice of the adhesive: Many adhesives are UV-curing, which requires the use of transparent and UV-permeable materials. For materials that block UV light, such as polycarbonates, long-wave LED curable adhesives are recommended.

All Vitralit® adhesives recommended for needle bonding are solvent-free and certified USP Class VI and/or ISO 10993 for use in medical equipment. In addition, high needle extraction forces were measured with all needle bonding adhesives even after several sterilization cycles. For visual quality inspection, fluorescent versions of our medical grade adhesives are also available. 

The choice of the adhesives requires a matching dispensing system for reliable and precise dispensing in a rapid production environment.

The high quality demands required for medical devices, as this needle bonding application, confirms the choice for bdtronic’s volumetric dispensing equipment. With the mini-dis solution provided by bdtronic, dispensing in microliter range is made easy, regardless of the adhesive viscosity. Thanks to the continuous volumetric dispensing, the dispensing is pulsation free ensuring optimal process speed, repeatability and accuracy.

Finally, the choice of the UV curing equipment depends on the adhesive and the wavelength which triggers polymerization. For needle bonding with Vitralit® products you can use either UV-A or visible LED light. 

Due to a special LED assembly and an own optimized electric power supply, Hönle LED Powerline LC guarantees a high-intensive irradiation for fastest curing and shortest cycle times. In addition, the irradiation time can be selected in a range of 0.01 – 99.99 sec and thus precisely adapted to the process requirements.

Hönle LED Powerline heads have a compact design for an easy integration into any production line. The high-intensive, water-cooled LED-UV is suitable for clean room operation.

New dual-curing potting compound for piezoceramics

Panacol is expanding its portfolio of dual-curing acrylic adhesives with the introduction of Vitralit® UD 8052 F. This material was developed for piezo actuators and sensors. It possesses a particularly high tear resistance for bonding ceramics and plastics.

Vitralit® UD 8052 F is a low viscosity, one-component UV curable adhesive. It is jettable, transparent, and fluoresces under UV light. Customized versions with different colors are available to facilitate improved process control. Its jet dispense capability makes high UPH (units per hour) values achievable, which is why Vitralit® UD 8052 F is the perfect choice for consumer electronics applications.

This potting compound can be cured in just a few seconds with UV light (320nm - 390nm) or visible light (405nm).

Panacol and Honle develop new system solution for filament winding processes

With the newly developed Vitralit® UD 1405 adhesive, Panacol has created an innovative adhesive system for fibre and filament winding. For high efficiency, Vitralit® UD 1405 adhesive can be applied during the winding process and immediately cured with high intensity LED curing systems from Dr. Hönle AG. This adhesive and curing system is ideal for carbon or glass fibre filament winding associated with Carbon Fibre Reinforced Polymer (CFRP) or Glass Fibre Reinforced Polymer (GFRP) manufacturing processes.  

Vitralit® UD 1405 can be used to wrap components such as hybrid rotor shafts for electric motors and high-voltage surge arresters. The adhesive-coated fibre-reinforced windings can be quickly cured with UV/Visible light. This innovative winding process is extremely space and time saving, and can produce significant processing cost savings.

Panacol’s Vitralit® UD 1405 is a transparent, solvent-free, one-component epoxy. Due to its low viscosity, Vitralit® UD 1405 has very good wetting properties. It can be cured in seconds by irradiation with UV (365nm) or Visible (405nm) light wavelengths. Depending on the fibre material and the wavelength used, layer thicknesses of several millimetres can be achieved exclusively by UV/Visible light curing. This epoxy can also be thermally cured after UV exposure to ensure that a complete cure is secured in areas shadowed from the UV light. For example, fibres or filaments can first be pulled through an adhesive bath, then wound onto the rotor or respective cylinder, and cured with UV or visible light. A secondary thermal cure will ensure that the layers of coated windings below the surface become fully cured.

After curing, Vitralit® UD 1405 is electrically insulating, shows minimal shrinkage and remains resistant at temperatures from -40° to 180°C. A glass transition temperature of over 130°C ensures reliable performance even under dynamic load at elevated temperatures.

For the most efficient UV curing system for fibre and filament winding processes, the LED Powerline AC/IC 820 HP from UV specialist Honle is the perfect choice. With intensities of up to 16,000 mW/cm², this LED system ensures very fast curing. Its light emission window is available in two standard sizes, 82 mm x 20 mm and 122 mm x 20 mm, which can be extended without gaps by stringing together multiple modules. When developing the LED Powerline AC/IC 820 HP, special attention was paid to a slim design. This makes it ideal for use where space is at a premium, such as automated winding equipment. 

The powerful LED Powerline AC/IC 820 HP can be powered and controlled using the optionally available LED powerdrive IC as a plug&play solution, or by using a customer supplied external power supply and PLC. This makes the LED Powerline an ideal solution for integrating high power LED curing systems into automated assembly processes.

Adhesives for cell contacting systems and battery packs

Panacol has developed specially formulated UV adhesives that protect welded joints on cell contacting systems and battery packs of electric cars from corrosion. The flexible adhesives enable vibration-resistant connections and have a low ion content. 

High-performance cell contacting systems (CCS), which combine individual lithium-ion battery cells for hybrid and electric vehicles to form battery packs, are often connected by welded strands or wires. To protect these welded joints from corrosion, Panacol has developed special low-ion UV adhesives that are applied as protective coatings. These adhesives provide additional mechanical support when subjected to vibrations and can compensate for thermal expansion of the different materials. 

UV-curing adhesives Vitralit® UV 2113 and Vitralit® UV 2114 are characterized by very high adhesion to many materials and meet the requirements of the automotive industry in terms of media and temperature resistance. The rheological properties of both Vitralit® UV 2113 and Vitralit® UV 2114 can be adapted to individual customer requirements. Fluorescent adhesive variations for optical process control are also available. 

In just a few seconds, these adhesives can be cured with light in the UVA or visible range. Both gas discharge lamps and LED spot systems can be used for curing. Perfectly matched to Panacol adhesives are the UV and LED UV curing systems from Dr. Hönle, for example the high-intensity LED Powerline AC/IC HP. 

For complex CCS geometries with shadowed areas, dual curing Vitralit® UD 8050 is the perfect choice. After UV irradiation, this ion-pure acrylate adhesive post-cures in the shadowed areas by reacting with humidity in the air.

Precision spraying of maskings and conformal coatings

The new preeflow® eco-SPRAY precision volume dispenser from ViscoTec makes for even and fast application of Panacol maskings and conformal coatings. The new technology yields perfect results with exceptional edge sharpness whether spraying low- or high-viscosity UV adhesives.

Spraying high-viscosity adhesives from Panacol onto large surfaces at more than 10,000 mPa becomes child’s play with the eco-SPRAY from ViscoTec: the new dispenser makes short work even of highly viscous and stable materials, such as Panacol’s liquid seal Vitralit® FIPG 60102 or masking compound Vitralit® MASK 20102, which is specially formulated for temporary coatings. The purely volumetric dosing of the eco-SPRAY system uses the endless piston principle to precisely meter and apply exact amounts regardless of their viscosity and supply pressure.

To achieve the required layer thickness, the applied amount can be changed simply by changing the air pressure, the adhesive volume, the distance to the substrate or the speed of application. The eco-SPRAY is intuitive in use and can be adapted to different materials and dosing processes with a range of supplied needle diameters and air caps.

Capable of handling viscous adhesives, the eco-SPRAY has also proven suitable for spraying and vaporizing low-viscosity conformal coatings. The two products used here were Vitralit® 2004 F and Vitralit® 2007 F – both dual-curing epoxy resin based adhesives. With the eco-SPRAY, both of these adhesives can be applied as surface coatings with high edge sharpness and cured in a continuous process with UV flood lamp, for example from Hönle’s UVAPRINT range. Here, the arc length can be ideally adapted to the PCB’s width.
