Aqueous resin composition and coated metal material having cured coating of the same |
摘要 |
An aqueous resin composition comprising prepared by a process comprising the steps of: reacting epoxy resins comprising: (A) an aromatic epoxy resin having a number average molecular weight of at least 9,000 and an epoxy equivalent of not larger than 9,000; and (B) an aromatic epoxy resin having a number average molecular weight of less than 9,000 and an epoxy equivalent of not larger than 5,000, and (C) a carboxyl group-containing acrylic resin having a glass transition temperature of at least 100 DEG C, to undergo partial-esterification to obtain an acryl-modified epoxy resin; neutralizing said acryl-modified epoxy resin with a base and dispersing the neutralized resin in an aqueous medium. Also disclosed is a coated metal material having a cured coated film of the aqueous resin composition. |
