Abstract, Room temperature-storable, heat-curable organopolysiloxane compositions which comprise silicon-bonded vinyl radicals, silicon-bonded hydrogen atoms, a platinum-type compound and characterized by an unsaturated hydrocarbon compound of the conjugated ene-yne type provide a release surface for tacky substances when coated onto the surface of a base material and heated even, mildly. The release surface possesses a time-stable release ability, particularly for pressure sensitive adhesive bearing articles such as tapes and labels.
