Patent No. U.S. 7,790,011 B2

BASF Coatings has received a patent for a method of coating an article comprised of blending a resin and a curing agent, wherein the resin is ionizable and has pendant amino groups; melting the resin and the curing agent at a temperature less than the thermal curing temperature of the curing agent; cooling the blended, molten resin and curing agent until solid to form a solid, blended resin-curing agent; grinding the solid, blended resin-curing agent into a powdered or granular form to produce a granular, solid resin-curing agent; dispersing the granular, solid resin-curing agent in an aqueous medium, wherein dispersing further includes adding an acidic salting agent; thereby forming a coating dispersion, wherein the resin in the coating dispersion is neutralized by the acidic salting agent, rendering the resin water-dispersible and the coating dispersion cathodically electrodepositable; and applying the coating dispersion to an article by cathodic electrodeposition; wherein the granular, solid resin-curing agent is transported to a coating preparation site prior to the dispersing step; or the solid, blended resin-curing agent is transported to a coating preparation site prior to the grinding step.
