Curable silicone composition.

摘要

A curable silicone composition comprising: (A) an organopolysiloxane containing at least two silicon-bonded unsaturated aliphatic hydrocarbon groups and having a viscosity of from 100 to 200,000 cst at 25 DEG C, (B) a vinyl group-containing organocyclopolysiloxane having the general formula (I): <CHEM> wherein R represents a hydrocarbon group having from 1 to 6 carbon atoms excluding unsaturated aliphatic hydrocarbon groups, and n represents an integer of from 3 to 8, (C) an organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms in the molecule, (D) a platinum family metal catalyst, and (E) a triazole compound. This curable silicone composition has ggod curing properties and can produce cured products having a markedly small permanent compression set.
