Abstract

The present invention relates to an organic solvent-based coating composition for coating a surface of a metal substrate in order to increase the coefficient of friction of the surface of said metal substrate, said composition comprising (i) at least one organic solvent; (ii) at least one particulate metal provided in a sheet metal and having a diameter in the range of 1 pm to 100 [mu] m; (iii) at least one metal carbide at a total concentration in the range of 0.1 wt% to 5 wt% based on the total weight of the coating composition; and (iv) at least one binder.

Description

technical field [0001] The present invention relates to an organic solvent-based coating composition for coating the surface of a metal substrate to increase the coefficient of friction of the surface of the metal substrate; and a method for preparing such a composition. The invention further relates to a method for coating a surface of a metal substrate; and a metal substrate having a surface comprising such a coating. Background technique [0002] Surfaces of metal substrates, especially ferrous metal substrates, are subject to corrosion, thereby reducing the material properties of such corroded metal surfaces. [0003] Typically, an anti-corrosion coating is applied to the surface of a metal substrate to protect the metal surface from corrosion. [0004] Such typical anti-corrosion coatings may include chrome coatings. Such chromium coatings provide another barrier layer at the metal surface since such chromium coatings are rapidly passivated by contact with ambient air...
