METHOD OF PROTECTING AND RESTORING CORRODED METAL SURFACES Russian patent published in 2004 - IPC

FIELD: corrosion protection. SUBSTANCE: invention relates to protection and restoration of surfaces operated under abrasive wear and corrosive media conditions in various area. Method consists in applying, onto a pure or rusty surface, primary coat based on composition containing epoxide resin, pigments, fillers, hardener, and organic solvents followed by drying to tackiness, laying insulating layer of composition containing epoxide resin, pigments, fillers, hardener, specularite, and organic solvents, and covering this layer with outside layer of composition containing epoxide resin, pigments, fillers, hardener, and organic solvents. Outside layer may also additionally comprise specularite. All layers contain hardener Cardolite NC 562 based on pentadecanylphenol and epoxide resin with epoxide equivalent weight 450-500. EFFECT: increased corrosion resistance of coating. 2 cl, 1 tbl, 2 ex
