A process for the preparation of a powder coating material, a powder coating material, as well as the use of effect pigments

摘要

The invention relates to a method for the manufacture of a powder coating material, in which a mixture containing binders, pigments and optionally fillers, additives and crosslinkers extruded and be subsequently ground. The proportion of pigment of this mixture comprises here at least partially made of surface-modified effect pigment with a low molecular weight polyethylene or polypropylene is coated. Dollars a the present invention also relates to a produced by this process, as well as the use of powder coating material with low molecular weight polyethylene or polypropylene coated effect pigments for the preparation of powder coatings.
