Abstract: Uv curable coating has no volatile compounds and environment friendly, good fluidity, curing time is short, the coating adhesion and abrasion resistance, good weather，Especially in recent years, uv-curable technology unceasing development and progress and saving energy and environmental protection consciousness of people, uv-curable paint is rapidly developing.Based on different Buddha's ketone diisocyanate and hydroxyl ethyl methacrylate for raw materials, The first reaction modified acrylate (Buddha's vision, ketone diisocyanate, Then respectively with low molecular weight polyether and amino organic silane reaction and low polyether modified low silane polymer, were primarily, and bisphenol A type of acrylic epoxy ester, photosensitizer, A kind of new-style composite coating.This coating for glass cured paint film coating hardness acuity H, Adhesion 0 level,175g RCA experiment.it resistance 300 times, Film smooth appearance, 1mm flexibility, Gloss experiment.it 90. Excellent performance.

Keywords：Light-cured coating; polyurethane; performance; acrylic ester;
