Title:
SILICONE RUBBER COMPOSITION AND PRODUCTION METHOD FOR LAMINATE OF FLUOROSILICONE RUBBER AND SILICONE RUBBER
Document Type and Number:
WIPO Patent Application WO/2020/022407
Kind Code:
A1
Abstract:
This silicone rubber composition comprises: (A) an organopolysiloxane that, per molecule thereof, has at least two alkenyl groups but does not have a fluoroalkyl group or has less than 20 mol% of a fluoroalkyl group relative to all silicon-bonded organic groups; (B) an organopolysiloxane that, per molecule thereof, has at least two silicon-bonded hydrogen atoms and at least 5 mol% of a fluoroalkyl group relative to all silicon-bonded organic groups; and (C) a hydrosilylation catalyst. The silicone rubber composition forms a silicone rubber to which fluorosilicone rubber compositions favorably adhere. This production method for a laminate produces a laminate in which there is favorable adhesion between a fluorosilicone rubber layer and a silicone rubber layer.
