ABSTRACT:
A curable silicone composition comprising at least the following components: (A) a diorganopolysiloxane having in one molecule at least two alkenyl groups; (B) at least two resin-like organopolysiloxanes that have different mass-average molecular weights as reduced into standard polystyrene measured gel permeation chromatography and that are composed of SiO4/2units, R12R2SiO1/2units, and R13SiO1/2units, wherein R1is an optionally substituted univalent hydrocarbon group that is free of aliphatic unsaturated bonds and R2is an alkenyl group; (C) an organopolysiloxane that contains in one molecule at least two silicon-bonded hydrogen atoms; and (D) a hydrosilylation catalyst; possesses excellent flowability and filling ability and that can be prepared without extreme viscosity even if the composition contains resin-like organopolysiloxanes required to form a cured silicone body of appropriate strength and hardness.
