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.
