C-UV 761 Technical Data Sheet

PRODUCT DESCRIPTION 产品介绍

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是一种单组分，粘度可变的紫外固化粘合剂。固化后该材料可形成弹性透明薄膜并具有不易发黄的显著特性。固化后该材料具有低收缩，强的抗冲击性能，优异的耐潮，耐化学腐蚀和耐热等优点。该产品的固化速度依曝光时间的不同可调，在1 mW/ cm²to 10 mW/ cm²的固化时间从1秒到15分钟可调。
