ABSTRACT:
Improved primer compositions comprise (A) at least one member of a specified group of ethylenically unsaturated organosilicon compounds containing silicon-bonded alkoxy groups, (B) silicone/organic copolymers prepared from esters of ethylenically unsaturated organic acids and organosilicon compounds derived from these acids, (C) organohydrogensiloxane curing agents and (D) a solvent. The improvement resides in the presence in the solvent of an ethylenically unsaturated alcohol containing from 4 to 6 carbon atoms. The alcohol constitutes at least 50 percent by weight of the solvent.
