Abstract
The present invention relates to coating compositions comprising a vinyl- or higher alkenyl-enblocked polydiorganosiloxane, a silicon-bonded hydrogen endblocked polydiorganosiloxane, a platinum catalyst, and an inhibitor which increase the release force of pressure sensitive adhesives (PSA's) adhered thereto. The compositions of the present invention can additionally comprise an organohydrogenpolysiloxane crosslinker. The present invention further relates to a method of release control by crosslink density (or bulk modulus) control.
