Electronic Component Potting

Two/single component or light curable potting materials that are specifically formulated to act as barriers against contamination, chemicals, moisture, and vibration damage. These materials dispense easily, cure quickly, and provide a protective surface that is dry and tack-free. LEDcure potting materials fully cure in fractions of a second under low intensity LED UV/visible or Visible light during automated production.

Electronic components inherently require protection from moisture and mechanical damage. For this reason, they are typically sealed with materials offering protective properties. These processes take place prior to next level of PCB assembly. Components such as capacitors, switches, and relays are typically designed with shallow cavities for containment, so that low viscosity potting materials may be dispensed quickly during automated production.

Panacol-USA offers single component, light curable potting materials that are specifically formulated to act as barriers against contamination, chemicals, moisture, and handling damage. These materials dispense easily, cure quickly, and provide a protective surface that is dry and tack-free. LEDcure adhesives are included in Tangent’s product selection for electronic component potting/encapsulating. LEDcure products from Tangent fully cure in fractions of a second under low intensity UV/visible or Visible light. They are ideal for use with LED light curing equipment.

Two additional brands of potting materials are offered by Tangent. They are Vitralit® light curable acrylates and epoxies, and Structalit® epoxies. Both are manufactured by Panacol-Elosol GmbH. Panacol-Elosol GmbH is a member of the Honle Group headquartered in Germany, and has been formulating and manufacturing adhesives for over 30 years. Tangent is the exclusive distributor for these adhesives in the Americas.

Tangent’s broad selection of potting materials bond to a variety of substrates including ABS, nylon, polycarbonate, and plated metals. Light curable materials are available with a secondary thermal cure catalyst in the event that shadowed areas exist in the potting field. Typical thermal curing schedules are identified on individual product technical data sheets.

View the adhesive selections listed below for a possible candidate for your potting application. Please contact Tangent to confirm your product selection and to secure additional application assistance, including samples and process recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Tangent will investigate other solutions that include development of adhesive specifically tailored to the complexity of your application.
