Abstract
The present invention provides an aqueous polymer emulsion with satisfactory resistance to electrochemical deposition property and good porosity sealing performance on casting metals or parts co-molded by two different metal materials. The aqueous polymer emulsion comprises at least one (meth)acrylic polymer prepared by at least two monomers comprising at least one alkyl (meth)acrylate and at least one unsaturated carboxylic acid, at least one corrosion inhibitor, and at least one chelating agent, wherein the at least one unsaturated carboxylic acid is present in an amount of less than 3.5% by weight, based on the total weight of the monomers.
