C-UV 761 Technical Data Sheet

PRODUCT DESCRIPTION 產(chǎn)品介紹

C-UV 761 is a one component, ultra-violet (UV) light curable adhesives which are available at different viscosities. When cured, it yields resilient transparent films and imparts outstanding non-yellowing characteristics. The cured material displays low shrinkage, excellent impact resistance, good humidity/chemical and excellent heat resistance. Adjustable curing speed from 1 second to 15 minutes at low UV exposure of 1 mW/ cm² to 10 mW/ cm².

C-UV 761是一種單組分，粘度可變的紫外固化粘合劑。固化后該材料可形成彈性透明薄膜并具有不易發(fā)黃的顯著特性。固化后該材料具有低收縮，強(qiáng)的抗沖擊性能，優(yōu)異的耐潮，耐化學(xué)腐蝕和耐熱等優(yōu)點(diǎn)。該產(chǎn)品的固化速度依曝光時(shí)間的不同可調(diào)，在1 mW/ cm²to 10 mW/ cm²的固化時(shí)間從1秒到15分鐘可調(diào)。
