Abstract:
The invention relates to a metal sheet, or a component made of a metallic material, comprising a layer system on the surface with at least the following layers: a) a conversion layer, comprising no more than 1 mg chromium per m2, b) a layer of a cross-linked organic polymer system with a thickness in the range of 0.5 to 2.5 μm, comprising, in relation to the total mass of said layer, 2 to 25 wt. % of an electrically conductive pigment having a specific weight of 3 g/cm3 maximum, however no more than 5 wt. % of the electrically conductive pigment having a specific weight of more than 3 g/m3. A coating material and a coating method for the production of the layer b).
