Patent ID: 7842177

Claim:
A method of producing an aqueous coating composition comprising: forming a solid pigmented resin-crosslinker mixture by a method comprising: blending an ionizable resin having pendent amino groups, a curing agent, and a pigment until homogenous at a temperature wherein the resin and the curing agent are molten; and cooling the blended resin, curing agent, and pigment until solid; thereby producing the solid pigmented resin-crosslinker mixture; shipping the solid pigmented resin-crosslinker mixture to a coating completion site; and dispersing the solid pigmented resin-crosslinker mixture in water, wherein dispersing further includes adding an acidic salting agent; thereby producing the aqueous coating composition, wherein the resin in the aqueous coating composition is neutralized by the acidic salting agent, rendering the resin water-dispersible and the aqueous coating composition cathodically electrodepositable.
