Releasing silicone composition and cured matter thereof

摘要

A releasing silicone composition, which in cured form has from medium to high bond release strength, comprising 0.1 to 10 parts by weight of an organopolysiloxane of the formula <IMAGE> wherein R1 is alkyl of 1-3 carbon atoms, or a phenyl group; each R2 is R1 or R3; R3 is ClH2l+1COOCH2CH2CH2- in which l is an integer from 14-20; m is an integer from 50-200; and n is an integer from 0-20, in a silicone composition comprising 100 parts by weight of an organopolysiloxane which contains at least two vinyl groups bonded directly to silicon atoms, from 0.1 to 30 parts by weight of an organohydrogenpolysiloxane which contains at least two hydrogen atoms bonded directly to silicon atoms, and a platinum catalyst.
