Claims11
An aqueous composition useful as an adhesive comprising at least one halogenated olefin polymer and at least one high-functionality epoxy resin, wherein said halogenated olefin polymer is selected from the group consisting of non-butadiene type halogenated olefin polymers produced by emulsion polymerization, non-butadiene type halogenated olefin polymers produced by methods other than emulsion polymerization, butadiene-type halogenated olefin polymers produced by methods other than emulsion polymerization, and mixtures thereof.
An aqueous composition useful as an adhesive comprising at least one halogenated olefin polymer and at least one high-functionality epoxy resin, wherein said composition is free from effective amounts of methylene donor compounds.
An aqueous composition useful as an adhesive comprising at least one halogenated olefin polymer, at least one high-functionality epoxy resin, and at least one water-soluble polymer containing pendant oxazoline groups.
An aqueous composition useful as an adhesive comprising at least one halogenated olefin polymer, at least one high-functionality epoxy resin, and at least one diacid-modified resin.
A composite structure comprising:
- (a) an elastomer substrate,
- (b) an adhesive,
- (c) optionally, one or more primers, and
- (d) a second substrate,
- wherein said adhesive is an aqueous composition comprising at least one halogenated olefin polymer and at least one high-functionality epoxy resin, wherein said halogenated olefin polymer is selected from the group consisting of non-butadiene type halogenated olefin polymers produced by emulsion polymerization, non-butadiene type halogenated olefin polymers produced by methods other than emulsion polymerization, butadiene-type halogenated olefin polymers produced by methods other than emulsion polymerization, and mixtures thereof.
