SILICONE RUBBER COMPOSITION

摘要

A silicone rubber composition comprising 0.01 to 50 weight percent of a perfluoroalkyl group-containing polydiorganosiloxane having on a side chain (F1) an organic group selected from the group consisting of polyoxyalkylene group-containing organic groups, C12 or higher alkyl groups, and polydialkylsiloxane chain-containing organic groups, and having on a side chain or at a molecular chain terminal (F2) a perfluoroalkyl group-containing organic group described by the general formula F(CF2)a-R1-, where R1 is selected from the group consisting of an alkylene group, an alkyleneoxyalkylene group, and a group in which =CO or ~COO- is present in an alkylene chain, and a is an integer of at least 3, and having a weight average molecular weight of at least 1000.
