Abstract

The invention provides for the use of mixtures of waxes which comprisea) a homopolymer or copolymer of C2-C18 &agr;-olefins, prepared by means of metallocene catalysis,and, as auxiliaries, one or more other waxes selected from the group consisting ofb) PE waxes,c) PTFE waxes,d) PP waxes,e) amide waxes,f) FT paraffins,g) montan waxes,h) natural waxes,i) macrocrystalline and microcrystalline paraffins,j) polar polyolefin waxes, ork) sorbitan estersfor improving the properties of coating materials.
