Abstract:
In a method for coating motor vehicle wheel rims, a polymer priming layer, a polymer intermediate layer, a decorative layer of a heat-cured polymer layer with embedded flake-like metal pigments covering the visible surface of the decorative layer, and a polymer cover layer are consecutively applied to the wheel rim metal surface. The coated wheel rims achieve a polished metal appearance by producing the polymer intermediate layer with a high-gloss surface and applying the decorative layer to the high-gloss surface of the polymer intermediate layer in the wet spraying method with a layer thickness of max. 2 μm, where it is dried at ambient temperature and, before applying the polymer cover layer, it is fixed to the polymer intermediate layer via a thermal post-treatment so that it adheres to the surface thereof with a cross-cut pull-off strength of Gt=0 to Gt=2.
