Abstract
A vulcanizing adhesive composition comprising a copolymerization oligomer of amino group-containing alkoxysilane and vinyl group-containing alkoxysilane, a nonionic surfactant of HLB 10-16 and an acid compound is an aqueous vulcanizing adhesive composition free from an organic solvent and for use in bonding of fluororubber to a metal, which is also effectively applicable to any of polyol-vulcanizable fluororubber and peroxide-vulcanizable fluororubber, showing a good adhesiveness even to stainless steel of poor wettability toward the conventional aqueous adhesive.
