ABSTRACT:
A flake-containing coating powder is obtained by admixing a coating powder that based upon a thermosetting resin and metallic or non-metalic flake. The powder and flake are mixed at a temperature in the range of above the softening temperature of the thermosetting resin of the coating powder but below the melting temperature of the thermosetting resin and with sufficient mechanical shear to prevent agglomeration of the coating powder particulates. Mixing is for a time sufficient to embed at least about 75% by weight of the flake into the coating powder.
