A curable composition which comprises: a) silane-functionalized colloidal silica; b) at least one curable monomer selected from the group consisting of aliphatic cyclic acrylate, urethane diacrylate and epoxy resin; and, c) at least one curing agent for curable monomer (b). The composition when cured exhibits scratch and abrasion resistant properties making it particularly well-suited for use as a protective coating for many different kinds of articles, e.g., CD and DVD discs and especially the more recent Blu-ray Discs, where these properties are highly desirable and even necessary.
一种可固化组合物,包括:a)
硅烷官能化胶体
二氧化硅;b) 至少一种可固化单体,该单体选自由脂环
丙烯酸酯、聚
氨酯二
丙烯酸酯和环氧
树脂组成的组;以及 c) 至少一种可固化单体(b)的固化剂。固化后的组合物具有耐刮伤和耐磨损的特性,因此特别适合用作多种不同物品的保护涂层,例如 CD 和 DVD 光盘,尤其是最新的蓝光光盘,这些物品非常需要甚至必须具有这些特性。
