Abstract
A curable silicone composition is disclosed. The curable silicone composition comprises: (A) a silicone resin consisting essentially of R3SiO1/2 siloxane units and SiO4/2 siloxane units, wherein each R is the same or different, and independently selected from halogen-substituted or unsubstituted monovalent hydrocarbon groups free of aliphatic unsaturated bonds; (B) an organopolysiloxane having at least two alkenyl groups per molecule and free of SiO4/2 siloxane units in the organopolysiloxane; (C) an organosiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; and (D) a hydrosilylation catalyst. The curable silicone composition can be cured to form a cured product having a high tensile strength in addition to a low modulus.
