Abstract

The invention provides an electrodepositable coating composition comprising a resinous phase dispersed in an aqueous medium, said resinous phase comprising: (1) an ungelled active hydrogen-containing, cationic salt group-containing resin; (2) an at least partially blocked polyisocyanate curing agent; and (3) a pigment component, wherein the pigment component comprises an inorganic, platelike pigment present in the resinous phase, wherein the electrodepositable coating composition contains less than 8 percent by weight of a grind vehicle, based on the total weight of solids in the electrodepositable coating composition. The invention also provides methods of improving the corrosion resistance of a metal substrate and coated substrates.
