摘要： The anticorrosive properties of a coating autodeposited on a metal substrate are improved by contacting the autodeposited coating with an aqueous solution containing Group IIA or Group IIB metal cations (e.g., calcium or zinc cations) and phosphate anions prior to curing. The rinse solution is preferably acidic and can be prepared, for example, from calcium nitrate and an oxy acid of phosphorus or zinc dihydrogen phosphate. Optionally, the rinse solution also includes an accelerator such as hydroxylamine.

摘要： Autodeposited coatings useful for protecting metal surfaces and in production of rubber-to-metal composites are obtained by curing adducts based on epoxy resins which are adhered to the metal surface. One or more epoxy resins, such as for example, the combination of a diglycidyl ether of bisphenol A and a flexibilizing epoxy resin, may be prereacted to form an adduct of higher average molecular weight than the starting epoxy resins. Said adduct may then be dispersed in water, with the resulting dispersion being used in an autodeposition bath composition.
