Abstract

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.
