ABSTRACT:
Silicone primer compositions comprising the reaction product of a resinous copolymeric siloxane and an organosilane are disclosed. The compositions find particular utility in promoting the adhesion of curable silicone coating compositions, comprising a liquid copolymeric organopolysiloxane and a polydiorganosiloxane, to solid substrates. Priming metal substrates with the certain compositions of the present invention additionally imparts improved corrosion resistance thereto when the substrates are subsequently coated with the above mentioned silicone coating compositions.
