Abstract

The invention relates to a mixture for applying a polymer, non-corrosive, electroconductive coating which can be shaped in a low-abrasive manner, to a base. Said mixture contains at least one substance A in the form of electroconductive hard particles, at least one substance B in the form of very soft or soft, inorganic, sliding, electroconductive or semiconductive particles, and/or at least one substance C in the form of metallic, soft or hard, electroconductive or semiconductive particles and/or soot, and optionally other constituents such as an anticorrosion pigment D, the sum of the parts by weight of the inorganic sliding particles B and the metallic particles and/or soot C amounting to between 0.25 and 99.5% of the parts by weight of the water-insoluble or only slightly water-soluble pigmentation S (A+B+C), and the size of the electroconductive hard particles A amounting to less than 10 ?m in relation to the particle size transfer value d99. The invention also relates to a method for producing a non-corrosive, viscoplastic coating on a base, said coating containing polymer and inorganic particles, and to an electroconductive coating containing polymer and inorganic particles.
