Abstract

The novel primer compositions of this invention comprise (1) a silane containing at least one t-butyl peroxy group and no silicon-bonded ethylenically unsaturated hydrocarbon radicals, (2) an organosilicon compound containing at least two alkoxy groups and at least one addition- or condensation reactive functional group per molecule, (3) an organotitanate ester and (4) sufficient organic solvent to achieve a solution of the desired viscosity. These compositions cohesively bond silicone rubber, particularly fluorosilicone rubber, to a variety of substrates.
