Curable silicone composition, cured product of same, and use of the composition

Abstract

Provided is a curable silicone composition that forms a cured product that can be rapidly cured at a low temperature, has excellent storage stability, is relatively hard from curing, and has low surface tack, and the cured product thereof and the usage. A curable silicone composition comprises: (A) an organopolysiloxane having a curing reactive functional group at a molecular terminal and the content thereof in a range of 0.001 to 10 mass %; (B) an organohydrogenpolysiloxane; (C) a hydrosilylation reaction catalyst; and (D) a branched organopolysiloxane having a curing reactive functional group in an amount exceeding 10 mass % in a molecule at a molecular terminal and containing 10 mol % or more of a branched siloxane unit. The content of component (D) is in the range of 0.1 to 5 mass % relative to the total amount of components (A) to (D).

Dependencies are inferred from the claim text.
