Abstract
The invention provides epoxy resin compositions comprising dispersed adhesion promoters to enhance adhesion to polyolefin resins, and multilayer composite coating systems useful for corrosion prevention to metal substrates which comprise an underlayer formed from such epoxy resin compositions, and thereover, a fuser polyolefin resin.
Claims
1. A powdered epoxy resin composition that bonds both to metal and to a polyolefin comprising, a thermoset epoxy resin, and a dispersed adhesion promoter for said polyolefin selected from the group consisting of oxidized polyethylenes and maleated polyethylenes, and maleated polypropylenes.
2. A two-layer composite coating system for a metal substrate comprising: a) a first layer comprising a powdered epoxy resin composition comprising a dispersed adhesion promoter capable of adhering to said metal substrate, selected from the group consisting of oxidized polyethylenes, maleated polyethylenes, and maleated polypropylenes and b) a second layer comprising a polyolefin resin.
3. A two-layer composite coating system according to claim 2 wherein said dispersed adhesion promoter is selected from the group consisting of oxidized polyethylenes, and maleated polyethylenes.
4. A two-layer composite coating system according to claim 2 wherein said dispersed adhesion promoter comprises maleated polypropylenes.
5. A two-layer composite coating system according to claim 1 wherein said thermoset epoxy resin is formed from epoxide containing moieties selected from the group consisting of aliphatic epoxides, polyglycidyl ethers of aliphatic polymers, bisphenol A, substituted bisphenol A derivatives, bisphenol F, substituted bisphenol F derivatives and mixtures thereof.
6. A two-layer composite coating system according to claim 5 wherein said epoxy resin is formed from an epoxide containing moiety selected from the group consisting of diglycidyl ethers of bisphenol A, diglycidyl ethers of bisphenol F, mixtures thereof, epoxy novolak, phenolic novolak and mixtures thereof.
7. A coated metal article having a two-layer composite coating system applied thereto, said layers comprising a) a fused epoxy resin underlayer, formed from a powdered epoxy resin composition comprising a dispersed adhesion promoter selected from the group consisting of oxidized polyethylenes, maleated polyethylenes, and maleated polypropylenes, and b) a polyolefin exterior layer, wherein said layers have an interfacial adhesion to said polyolefin layer of at least about 3.5 N/mm.
