Kind Code:
A1
Abstract:
The present invention relates to a curable silicone composition which is composed of at least (A) an organopolysiloxane that has at least two alkenyl groups and at least one aryl group in each molecule, (B) a polyoxyalkylene compound represented by general formula XO-(C2H4O)p(CnH2nO)q(YO)r-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 3-6; p and q are integers satisfying 2 ≤ p ≤ 100 and 0 ≤ q ≤ 50; and r represents 0 or 1), (C) an organopolysiloxane that has at least two silicon-bonded hydrogen atoms in each molecule, and (D) a hydrosilylation reaction catalyst. This composition forms a cured product which is not susceptible to turbidity or coloring even if exposed to high temperature and high humidity.
