Abstract
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.
