摘要： A curable silicone composition is capable of forming a cured product having excellent elongation characteristics.
The curable silicone composition, comprises: (A) a resinous alkenyl group-containing organopolysiloxane containing less than two alkenyl groups per molecule on average, which is represented by average unit formula (I): (R13SiO1/2)a(R12SiO2/2)b(R1SiO3/2)c(SiO4/2)d(XO1/2)e, where in formula (I), each R1 is independently a monovalent hydrocarbon group including an alkenyl group, while the number of alkenyl groups per molecule is less than two on average, X is a hydrogen atom or an alkyl group, 0≤a≤1, 0≤b≤1, 0≤c≤0.9, 0≤d 0; (B) an organohydrogenpolysiloxane having two or more silicon atom-bonded hydrogen atoms per molecule; and (C) a curing reaction catalyst.

摘要： A curable silicone composition comprises (A) a resinous alkenyl group-containing organopolysiloxane including at least two alkenyl groups per molecule and at least one (SiO4/2) unit, (B) a resinous organohydrogenpolysiloxane including at least two silicon atom-bonded hydrogen atoms per molecule and at least one (SiO4/2) unit, (C) a catalyst for hydrosilylation reaction, and (D) a curing reaction inhibitor. The curable silicone composition exhibits practically effective curability even at low temperatures, has a low shape deformation and shrinkage rate during curing, can be cured in a short period of time, and can form a transparent and high-hardness cured product.
