    摘要： An aqueous composition includes in dispersion an active hydrogen-functional resin and a uretdione compound. The uretdione compound is a crosslinker for the active hydrogen-functional resin. The uretdione compound does not release volatile by-products during the curing reaction, which reduces regulated emissions and increases the amount of coating solids weight converted to cured coating on the substrate. The aqueous dispersion coating may be made by combining a solid uretdione compound with a molten, water-dispersible resin, salting the water-dispersible resin if necessary, and dispersing the resin mixture in water. The molten, water-dispersible resin may have functionality reactive with the uretdione compound, or the coating composition may contain a further water-dispersible resin having functionality reactive with the uretdione compound. The coating composition of the invention is applied to a substrate and then cured to produce a cured coating layer on the substrate. In a particular embodiment, the coating composition of the invention is electrodepositable and is coated onto the substrate by electrodeposition.

    摘要： A granular coating feedstock is prepared by melting a resin, which can be a solid, 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 agent is ground to produce a granular coating feedstock. The feedstock is readily storable or shippable to a location for coating preparation. Alternatively the feedstock can be ground after shipping. An aqueous coating composition 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.
