ABSTRACT:
A method of electrocoating an electroconductive substrate utilizes an aqueous electrocoating composition containing an electrodepositable water dispersible film forming polymer and a pigment grind composition. The pigment grind composition contains pigment, electrodepositable water dispersible acrylic polymer and a reactive diluent. The reactive diluent has a number average molecular weight of between about 200 and about 2500 and is selected from polyalkylene glycols, polyalkylene glycol ethers, glycol ether formals or mixtures of these. The pigment grind composition has a volatile organic content of less than two pounds per gallon. The method is particularly suitable for anodic electrodeposition.
