  • Patent number: 7842177
    Abstract: A pigmented granular pigmented coating feedstock is prepared by melting a resin, which can be a solid resin based on polymerizable ethylenically unsaturated monomer or epoxy based resin, and a solid or viscous curing agent, blending the molten mass, and cooling to form a solid. The solid blend of resin and curing agent is ground to produce a granular feedstock. The feedstock is readily storable or shippable to a location for coating preparation. Alternatively a solid coating can be ground after shipping. An aqueous coating is made by dispersing the feedstock in water and mixing to form a dispersion. A salting agent and at least one additive can be added to form an aqueous coating composition. An article can be coated with the dispersion, for example, by electrodeposition.
