Adhesives for Needle and Syringe Assembly

Panacol-USA has developed a series of LED light curable adhesives under the Vitralit® brand name that are ideally suited for bonding stainless steel cannula into hubs of various substrates and configurations.

Panacol-USA’s LEDcure family of adhesives are products that fully cure in fractions of a second under low intensity UV/visible or visible light. This provides manufacturers with the ability to select more economical curing systems for their assembly process, including those based on LED technology.

Each Panacol-USA adhesive is typically available in several viscosity ranges to better match manufacturers’ hub designs and process requirements. Product specific viscosities can also be developed to optimize dispense/cure cycles involving unique hub and well configurations. Panacol-USA adhesives are moisture resistant, and when fully cured, possess dry, tack-free surfaces. The adhesives are specifically formulated to meet USP Class VI and ISO 10993 biocompatibility standards, and are compatible with gamma, EtO, peroxide plasma, and E-Beam sterilization processes. Autoclave sterilization may be possible in limited applications.

Panacol-USA’s needle and syringe assembly adhesives create high strength bonds that deliver consistent performance after sterilization and aging. To achieve maximum pull-strength with hubs molded from low surface energy polymers such as polyethylene and polypropylene, it is necessary to apply surface pre-treatment (corona, plasma, etc.), and/or incorporate annular rings in the hub inner well diameter.

These adhesives are ideal for the high volume production of disposable hypodermic needles, syringes, safety syringes, pen needles, winged infusion sets, and biopsy needles. Solvent-free and single component, Panacol-USA medical device adhesives can be easily and precisely dispensed through stainless steel valves commonly used in device assembly processes. Fluorescing versions of each adhesive are available to enhance automated detection systems that monitor adhesive volume and profile.
