Abstract

In silicone release coatings obtained by crosslinking compositions whose constituents comprise (A) alkenyl-functional polyorganosiloxane and an SiH-functional organosiloxane, PA1 the release force is regulated by using an SiH-functional organosiloxane (B) having from 0.1 to 60 mol-% of radicals which are incompatible with the compositions, PA1 said radicals being regarded as incompatible with the compositions when a mixture of 1 part by weight of SiH-functional organosiloxane (B) having 30 mol-% of incompatible radicals and 9 parts by weight of alkenyl-functional polyorganosiloxane (A) forms more than one phase at 20.degree. C.
