This presentation will review UV epoxies including the mechanism of action of epoxy (cationic) UVs and acrylic (free radical) UVs, along with best practices for proper curing of these adhesives. In addition, attendees will learn about new epoxy/UV hybrid systems designed to improve processing/throughput. Hybrid systems combine the convenience of a UV with the robustness of an epoxy adhesive for enhanced performance parameters that are equal to or better than thermal cured epoxies alone. The UV allows for immediate tacking, and thermal post-cure provides excellent environmental resistance. Lastly, the presentation includes a complete review of proper UV lamp selection (type and format), proper exposure/intensity and measurement, and optimal product selection (cationic or free radical).
