Aqueous electrodeposition coating composition, method for coating metal body of metal including substitution of phosphate pretreatment, and manufacturing method of the electrodeposited coating composition of aqueous solution

摘要

An aqueous electrodeposition coating composition comprising a cathodically depositable binder, the binder comprising an amine-functional phosphorylated resin, provides corrosion protection equivalent to that obtained by the conventional phosphate pretreatment-electrodeposition coating process.
