Patent ID: 7919181

Claim:
A metal sheet or a metal component, comprising: a multilayer coating system on at least one surface of a metal sheet or metal component, said multilayer system comprising at least: a) a conversion layer deposited on the metal sheet or metal component, said conversion layer containing no more than 1 mg of chromium per m 2 ; b) a layer of a crosslinked organic polymer system deposited on the conversion layer, said layer of a crosslinked organic polymer system having a thickness in a range from 0.5 to 2.5 μm, and comprising, relative to total mass of said layer of a crosslinked organic polymer system: 1) 2 to 25 wt. % of an electrically conductive pigment having a relative density of at most 3 g/cm 3 ; and 2) no more than 5 wt. % of an electrically conductive pigment having a relative density of more than 3 g/m 3 ; wherein said metal sheet or metal component bearing said multilayer system, without an additional application of oil, exhibits a coefficient of friction “μ” of below 0.1 in tribometer friction wear tests at a contact pressure in a range from 300 to 700 daN.
