Patent ID: 7718723

Claim:
A curable fluoropolyether rubber composition comprising (A) a straight-chain fluoropolyether compound having at least two alkenyl groups in a molecule and a perfluoropolyether structure in the backbone, (B) an organosilicon compound having at least two silicon atom-bonded hydrogen atoms in a molecule, (C) an organosilicon compound having a silanol group in a molecule and a melting point of at least 60° C., wherein said organosilicon compound has the formula (I) or (II): in which Ar 1 is a substituted or unsubstituted, monovalent aromatic hydrocarbon group of 6 to 12 carbon atoms, Ar 2 is a substituted or unsubstituted, divalent aromatic hydrocarbon group of 6 to 12 carbon atoms, R is a substituted or unsubstituted, monovalent hydrocarbon group of 1 to 10 carbon atoms, m is 0, 1 or 2, n is 1, 2 or 3, and the sum of m+n is from 1 to 3, and (D) a hydrosilylation catalyst.
