Abstract:
1. A fluororubber-metal laminate gasket material, which comprises a metal steel sheet, a zirconium element-, a phosphorus element-, and aluminum element-containing surface-treating agent layer, a silica-containing thermosetting phenol resin-based vulcanizing adhesive layer and a fluororubber layer, as successively laid upon one another on the metallic steel sheet, where the silica-containing thermosetting phenol-based vulcanizing adhesive is a thermosetting phenol resin-based vulcanizing adhesive comprising silica, thermosetting phenol resin and cresol novolak-type epoxy resin or phenol novolak-type epoxy resin, and further containing 11-80 parts by weight of an aliphatic amine-based compound of a mixture thereof with an imidazole-based compound as a curing accelerator comprising 100-10 wt.% of aliphatic amine-based compound and 0-90 wt.% of imidazole-based compound on the basis of 100 parts by weight of the thermosetting phenol resin.
