CURABLE ORGANOPOLYSILOXANE COMPOSITION AND METHOD FOR MANUFACTURING THE SAME

摘要

A curable organopolysiloxane composition comprises the following: (A) an organopolysiloxane having at least two silicon-bonded alkenyl groups and having an average unit formula (I): (R12SiO2/2)a(R23SiO1/2)b(R3SiO3/2)c(SiO4/2)d(CH2CH2)e; (B) a branched organopolysiloxane having at least one silicon-bonded alkenyl group and having a siloxane unit of formula R4SiO3/2; (C) an organopolysiloxane having an average unit formula (II) being capped with H: (R52SiO2/2)f(R63SiO1/2)g(R7SiO3/2)h(SiO4/2)i(CH2CH2)j; and (D) a catalyst, wherein R1 to R7 and a to j are as defined in the specification.
