Adhesive composition

Abstract

Abstract PURPOSE:To provide an adhesive compsn. having excellent storage stability, tack and adhesion between fluororubber and iron surface, consisting of a specified fluororubber compsn., a tackifier and an org. solvent. CONSTITUTION:5-50wt% fluororubber compsn. (A) contg. a difluoroethylene/ hexafluoropropylene copolymer rubber of formula I and/or a difluoroethylene/ hexafluoropropylene/tetrafluoroethylene terpolymer as rubber component and additives such as carbon black, peroxide, softening agent, antioxidant, etc., 1-20wt% chlorotrifluoroethylene/cyclohexylvinyl ether/ethylvinyl ether copolymer (B) as a tackifier which is compatible with the fluororubber and can impart tack to an adhesive, and 30-94wt% org. solvent (C) such as methyl ethyl ketone are blended together to obtain an adhesive compsn. which is low in toxicity and suitable for use as an adhesive for the lining of fluororubber.
