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 SiOunits, RRSiOunits, and RSiOunits, wherein Ris an optionally substituted univalent hydrocarbon group that is free of aliphatic unsaturated bonds and Ris 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.
