PRIMER COMPOSITIONS CONTAINING PHENYLSILOXANE RESIN

摘要

Primer compositions containing an organopolysiloxane resin having at least 5 percent of the organic radicals as phenyl, a trialkoxysilane containing unsaturation such as gamma-methacryloxypropyltrimethoxysilane, an organic titanate, an organic solvent, and optionally a tetraalkoxysilane can be used to adhere heat vulcanized silicone rubber to a substrate. The resulting adhesion strength does not decrease when exposed to high temperatures or hot silicone oil.
