The present invention relates to a curable silicone release coating composition comprising a mixture of an organopolysiloxane containing at least two alkenyl groups per compound, an organohydrogensilicon compound, inhibitors having a boiling point of up to 130.degree. C. at atmospheric pressure, inhibitors having a boiling point of at least 170.degree. C. at atmospheric pressure a platinum group metal-containing catalyst, and optionally a diluent. The silicone release coating compositions are stable when stored at room temperature, especially when the composition is used on a coating roll for the production of a thin films. The compositions of this invention also quickly form a cured film having good release properties for adhesive materials at a comparatively low temperatures.

Silicone release coating compostions

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.
