Abstract
An adhesive composition using as the primary binder an emulsion of butadiene-vinylidene chloride copolymer is disclosed. The composition is particularly suited for binding rubber to metal in a variety of uses such as vibration damping devices. The adhesive composition has resistance to hot water and or water glycol solutions.
Claims5
A laminate comprising;
- (a) a metal substrate having an interfacial bond area,
- (b) a crosslinked elastomer,
- (c) an adhesive composition bonding said metal substrate to said elastomer and in direct physical contact with said elastomer and with the interfacial bond area of said metal substrate, said adhesive composition comprising;
- (1) a diene-vinylidene chloride based polymer derived from a water-based latex, said diene-vinylidene chloride based polymer having 30 to 90 weight percent of its repeat units derived from conjugated dienes free of halogens and having from 4 to 6 carbon atoms, 5 to 70 weight percent of its repeat units derived from vinylidene chloride, up to 20 weight percent units derived from styrene or alkyl substituted styrene or mixtures thereof;
- and up to 20 weight percent units derived from one more other ethylenically unsaturated monomers having from 3 to 12 carbon atoms,
- (2) one or more polynitroso compounds, and
- (3) one or more bismaleimide compounds
- wherein the interfacial bond area of said metal substrate is free of any organic primer coating other than said adhesive composition and an optional inorganic phosphate corrosion inhibitor.
