OP-4-20632: Ultra Light-Weld®
High Tg Optical Adhesive |
|
|
Ultra Light-Weld® OP-4-20632 is a clear UV/Visible light-curable
optical adhesive designed for durable bonding of optical glass and prisms. OP-4-20632 adhesive is engineered for maximum resistance to yellowing for light-path applications and to maintain its dimensions through thermal excursions. This
optical adhesive has high bond strength to optical glass and most metals. Although the product fully cures in seconds upon exposure to UV/Visible light, heating the UV-cured product to 150°C for one hour will increase the Tg to 100°C and may further improve bond strength.

DYMAX materials are solvent free and cure upon exposure to light. Their
ability to cure in seconds results in lower processing costs. When cured with DYMAX UV light curing spot lamps, focused beam lamps, or flood lamps, they deliver optimum speed and performance for maximum efficiency. DYMAX lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11EC.
