Abstract

Procedure for obtaining pigmented coating powders, color-matched, tinted in an airship and reproducible manner, characterized in that dispersions containing resins or mixtures of resins, dispersed fillers, pigments, as well as catalysts, if appropriate, soluble dyes and other auxiliary agents, dissolved in organic solvents, are released from the solvent in evaporators, especially screw-type evaporators, under heating and vacuum application, and the extracted fusion is granulated, ground and, if necessary, sieved and classified.
