Abstract
The disclosure relates to curable polyepoxysilane com pounds and compositions, methods related lo curing or such compounds via hydrolysis and/or condensation to form coatings on a substrate, and coated articles formed from the curable polyepoxysilane compounds. The polyepoxysilane compounds are silane-functional precursors and can be used as coatings (or pretreatments) on various suhstrates (e.g., metals such as aluminum) and provide a substantial improvement in corrosion resistance relative to other anti-corrosion coatings. The silane-functional precursors can be prepared by reaction or functional silanes (e.g.. amino. functional silanes or other epoxide-reactive functionalized silanes) with epoxide-containing organic or hydrocarbon compounds and oligomers/polymers thereof (e.g., glycidyl-type ethers or other epoxide-/oxirane-functionalizcd hydrocarhon compounds), for example including hydrocarbons with one or more aromatic hydrocarbon groups (e.g .. in an aromatic polyether).
