Acryloyloxymethyltrimethoxysilane

CAS Number
21134-38-3

Description

Acryloxy functional alpha silane — the acrylate group sits one carbon from silicon instead of the usual three, giving faster hydrolysis and cure than the propyl-spacer methacryloxy silanes already in the range. The acrylate group copolymerizes with other unsaturated monomers while the trimethoxysilyl end bonds to glass, metal and mineral surfaces.
