Light-Curable Epoxies respond to visible and UV light.

Cationic Type V157 and V197 epoxies can be applied and irradiated with long-wave UV light in the range of 325-380 nm or with visible light in the range of 400-500 nm. Wide-range response lets adhesives be processed with many different existing light sources. Response to longer wave visible light is beneficial when bonding various engineering plastics such as Kapton and Lexan, which do not...
