RADIATION-CURABLE COMPOSITIONS HAVING FAST CURE SPEED AND GOOD ADHESION TO GLASS

摘要

A radiation-curable composition for use as an optical fiber material or coating comprising the combination of the following pre-mixture ingredients: (A) about 5 wt.% to about 95 wt.& of one or more radiation-curable oligomers, (B) about 5 wt.% to about 95 wt.% of one or more monomer diluents, (C) optionally, one or more photoinitiators, (D) about 0.1 wt.% to about 30 wt.% of one or more adhesion promoters represented by: R<1>-L-Si(OR<2>)3 wherein R<1> is a group comprising an ethylenically unsaturated radiation-curable group; and said three R<2> groups independently of each other are C1-C10 groups; and L is a linking group which comprises one or more alkoxy or branched propoxy groups.
