Cathodic electrocoating process

摘要: Heat cured coatings cathodically electrodeposited from an aqueous dispersion of (a) ionized reaction product epoxy resin and a monoamino alcohol or phenol, said also having pendant hydrocarbon group, (b) acid-functional aminoplast resin, (c) water soluble acid solubilizer, where the is free which will be retained in heat resinous coating are found to provide exceptional resistance corrosion ferrous metal substrates upon exposure salt spray detergent solutions.
