摘要： This invention relates to a silicone composition comprising: (A) a mixture of (i) a linear trimethylsiloxy-terminated polydiorganosiloxane containing at least 2 alkenyl groups having at least 4 carbon atoms and (ii) optionally a linear dimethylalkenylsiloxy-terminated polydiorganosiloxane, (B) a polyorganohydrogensiloxane, (C) a catalytic quantity of a platinum catalyst, and (D) an inhibitor. The silicone compositions of this invention make it possible to form cured release films with low resistance to peeling when peeling is carried out at high speeds, and with the possibility of controlling the resistance to peeling between low and high values when peeling is carried out at low speeds. The silicone compositions of this invention also are not subject to a decrease in the coefficient of residual adhesion in the adhesive material applied onto a cured release film.
