ABSTRACT:
A process for the manufacture of a powdered coating material having a basis of hardenable synthetic resins, hardeners and pigments selected from the group consisting of metals, metal alloys, and mica for coatings with a metallic appearance wherein the single components are mixed in a finely divided state under an atmosphere of a protective gas and wherein the mixture is plasticized, under homogenization, at a temperature at which the viscosity of the synthetic resin is higher than the drop viscosity, but at most sufficiently high as to guarantee the flow, is homogenized by shearing stress and transformed into a powdered state, a powdered coating material prepared by said process and an article being coated with said coating material.
