Abstract
Disclosed is a curable silicone composition. The composition comprises: (A) an organopolysiloxane having at least two alkenyl groups and at least one aryl group in each molecule; (B) a polyoxyalkylene compound represented by the general formula: XO—(CHO)(CHO)(YO)—X, wherein, each X represents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, an acryl group, or a methacryl group, provided that at least one X in each molecule is the alkenyl group, the acryl group, or the methacryl group, Y represents a divalent hydrocarbon group, n represents an integer of 3 to 6, p and q are integers satisfying: 2≤p≤100 and 0≤q≤50, and r represents 0 or 1; (C) an organopolysiloxane having at least two silicon bonded hydrogen atoms in each molecule; and (D) a catalyst for a hydrosilylation reaction. The composition forms a cured product having improved properties.
