Abstract
A silicone rubber composition is provided. The silicone rubber composition comprises: (A) an organopolysiloxane having at least 2 alkenyl groups per molecule, and not having fluoroalkyl groups or having fluoroalkyl groups in a proportion of less than 20 mol % of all silicon atom-bonded organic groups; (B) an organopolysiloxane having at least 2 silicon atom-bonded hydrogen atoms per molecule along with fluoroalkyl groups in a proportion of at least 5 mol % of all silicon atom-bonded organic groups; and (C) a hydrosilylation reaction catalyst. The silicone rubber composition forms a silicone rubber to which a fluorosilicone rubber composition adheres well. Manufacturing methods are also provided, where laminates in which a fluorosilicone rubber layer and a silicone rubber layer adhere well are manufactured.
