ABSTRACT:
A crosslinkable fluororubber composition comprising (A) a liquid perfluoro compound having alkenyl groups and a divalent perfluorolakylene or perfluoropolyether structure, (B) a reinforcing filler, (C) a surface treating agent having a fluoroalkyl or fluoropolyalkyl ether group and a silanol group, (D) an addition reactive compound having hydrosilyl groups, and (E) a hydrosilyl or peroxide crosslinker is prepared by mixing components (A) to (C) to form a liquid or paste composition, adding component (D) thereto to form a millable composition, and mixing component (E) therewith. The composition is effectively roll workable and cures into products having excellent physical properties.
