UV cure Adhesives

Fast UV-curable high Tg, low outgas, low CTE epoxy sealants for chip edge sealing, OLED/PLED, and liquid crystal chip edge sealing, chip bonding, semiconductor and optoelectronic packaging. Very inert materials with no interaction with liquid crystal or OLED or PLED materials.  Low moisture and gas permeability, suitable for hermetic sealing applications.  The cured sealants are compatible with solder reflow temperatures up to 280°C and meet many reliability standards such as Telcordia and JDEC Level 3.  These adhesives are designed for UV-transparent substrates; for opaque substrates or assemblies with shaded regions, see the Dual Cure Adhesives and UV-Snap Cure Adhesives pages.
