THERMOSETTING SILICONE COMPOSITION, SHEET, AND CURED SILICONE PRODUCT

WIPO Patent Application WO/2021/229940

A1

The present invention is a thermosetting silicone composition including: (A) an organopolysiloxane having average formula (1) of (SiO2)a1(R1 3SiO1/2)b1(X1O1/2)c1 (1) (50-99.9% of R1 is a methyl group, 0.1-50% of R1 is an alkenyl group, and X1 is a hydrogen atom or an alkyl group.); (B) an organopolysiloxane having average formula (2) of (SiO2)a2(R2 3SiO1/2)b2(X1O1/2)c2 (R2 is a hydrocarbon group including no alkenyl group, and X1 is a hydrogen atom or an alkyl group.); (C) an organopolysiloxane having average formula (3) of (R3 2SiO)a3(R3 3SiO1/2)b3 (20% of R3 is a methyl group, and 0.0001-25% of R3 is an alkenyl group.); (D) an organic peroxide; and (E) a solvent. According to said feature, provided is a thermosetting silicone composition which has excellent stability in an uncured state without adding a reaction control agent, and from which a cured product having a high hardness can be obtained.
