Zusammenfassung:An (A) additive organopolysiloxane composition is disclosed, which includes (A1) a branched organopolysiloxane polymer comprising M, D and Q siloxy units, (A2) a silicone resin, and (A3) a polydiorganosiloxane oligomer. A curable composition is also disclosed, the curable composition including the (A) additive organopolysiloxane composition, (B) an organosilicon compound having at least two silicon-bonded hydrogen atoms per molecule, and (C) a hydrosilylation catalyst. A method of preparing the curable composition, and a method of forming a film with the curable composition are also disclosed. The compositions and methods are useful for forming silicone release coatings with high release force.
