ORGANOSILICONE RUBBER COMPOSITION, AND LAMINATE OF ORGANOSILICONE RUBBER AND FLUOROSILICONE RUBBER

摘要

PROBLEM TO BE SOLVED: To provide an organosilicone rubber composition excellent in adhesiveness between a silicone rubber composition and a fluorosilicone rubber composition, and a laminate (laminated structure) of an organosilicone rubber comprising a cured product of the organosilicone rubber composition and fluorosilicone rubber.;SOLUTION: This organosilicone rubber composition includes: (A) 100 pts.mass of an organopolysiloxane expressed by average composition formula (1): R_aSiO_(4-a)/2 (where Rs are each the same or different non-substituted or cyano-substituted monovalent hydrocarbon group; a is a positive number of 1.90-2.05); (B) 2-100 pts.mass of a silica-based filler; (C) 0.01-30 pts.mass of a specific organohydrogenpolysiloxane having at least one each of a siloxane unit containing a fluoroalkyl group and a siloxane unit containing a hydrogen group in one molecule; and (D) a catalytic amount of an organic peroxide vulcanizing agent.;COPYRIGHT: (C)2013,JPO&INPIT
