An improved method is provided for bonding together layers of fluoroelastomer compound and butadiene-acrylonitrile polymer compound by incorporating into one or both of the compounds a polysulphidic silane compound prior to vulcanization. There is also provided a vulcanized hose having an inner layer of fluoroelastomer compound and an outer layer of a butadiene-acrylonitrile polymer compound containing a polysulphidic silane compound incorporated into either layer.

An improved method of bonding a layer of a fluoroelastomer compound to a layer of a butadiene-acrylonitrile polymer compound, said fluoroelastomer compound containing a fluoroelastomer based on vinylidene fluoride and hexafluoropropylene optionally also containing tetrafluoroethylene, perfluoromethy

An improved method of bonding a layer of a fluoroelastomer compound to a layer of a butadiene-acrylonitrile polymer compound, said fluoroelastomer compound containing a fluoroelastomer based on vinylidene fluoride and hexafluoropropylene optionally also containing tetrafluoroethylene, perfluoromethylvinyl ether or ethylenically unsaturated olefins, and containing one or more inorganic acid acceptors selected from magnesium oxide, cadmium oxide, calcium oxide, calcium hydroxide and zinc oxide, wherein the improvement is the incorporation into each of the fluoroelastomer compound and the butadiene-acrylonitrile polymer compound from about 1 to about 3 parts by weight per 100 parts by weight of the fluoroelastomer and of the butadiene-acrylonitrile polymer of a polysulphidic silane compound prior to bonding the two layers together and vulcanizing the layers in contact with each other.
