Title:
ADDITION REACTION-CURABLE ORGANOPOLYSILOXANE COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2024/070866
Kind Code:
A1
Abstract:
An addition reaction-curable organopolysiloxane composition containing: (A) (A-1) an organopolysiloxane that has a silicon atom-bonded alkenyl group in one molecule and does not have a (meth)acrylic group and (A-2) an organopolysiloxane having an alkenyl group and a (meth)acrylic group in one molecule; (B) an organohydrogenpolysiloxane having two or more silicon atom-bonded hydrogen atoms (Si-H groups) on average in one molecule; and (C) 1-200 ppm of a platinum group metal-based catalyst in terms of platinum group metal mass based on the total amount of the composition, wherein addition reaction curing can be achieved using a small amount of the platinum group metal-based catalyst, a cured film having a peeling force equivalent to those of conventional cured films can be formed, and the composition has a reduced amount of cyclic low-molecular-weight siloxane, a less cloudy appearance, and suppressed sedimentation over time.
