Abstract:
1. A hydrosilylation reaction-curable organopolysiloxane composition comprising (A) a methylphenylalkenylpolysiloxane that has at least two silicon-bonded alkenyl groups per molecule, wherein diphenylsiloxane units are no more than 5 mole % of the total siloxane units and phenyl groups are at least 20 mole % of the total silicon-bonded organic groups in the molecule, (B) a methylphenylhydrogenpolysiloxane that has at least two silicon-bonded hydrogen atoms per molecule, wherein diphenylsiloxane units are no more than 5 mole % of the total siloxane units and phenyl groups are at least 20 mole % of the total silicon-bonded organic groups in the molecule, and (C) a hydrosilylation reaction catalyst, wherein the diphenylsiloxane units are no more than 5 mole % of the total siloxane units in this composition.
