Title:
CURABLE ORGANOPOLYSILOXANE COMPOSITION, A USE THEREOF, AND A LAMINATE PREPARED FROM THE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/138660
Kind Code:
A1
Abstract:
This invention relates to a novel curable organopolysiloxane composition comprising: (A) an organopolysiloxane having at least two alkenyl groups in each molecule; (B) an organohydrogenpolysiloxane in an amount sufficient to provide a value of 1.1 : 1 to 10 : 1 (SiH: alkenyl group) for the molar ratio of silicon-bonded hydrogen atoms in the organohydrogenpolysiloxane to the alkenyl groups in the component (A), wherein the component (B) consists of the following components (B1) and (B2) at a mass ratio of (B1) / (B2) in the range from 100/0 to 15/85: (B1) an organohydrogenpolysiloxane having at least three silicon-bonded hydrogen atoms in each molecule and a silicon-bonded hydrogen content [Si-H] mass % satisfying the following equation: 0 < [Si-H] mass %< 5/ (DP) 0.5 wherein DP designates the average number of siloxane units in each molecule calculated by the number average molecular weight of component (B1), and said DP is in the range from 5 to 1000; (B2) an organohydrogenpolysiloxane having at least one silicon-bonded hydrogen atom in each molecule, which is different from the component (B1); and (C) a hydrosilation reaction catalyst in a catalytic amount.
