Abstract of US Patent Application 20040186201- Corrosion resistant coatings containing carbon: A coating composition comprising an effective corrosion-inhibiting amount of a carbon pigment is provided. In one embodiment, the corrosion-inhibiting carbon pigment is further comprising other components such as extenders, including neutral to slightly acidic generating extenders and acidic generating extenders, are earth compounds, amino acids and amino acid derivatives, gelatin and gelatin derivatives, organic-based exchange resins, and combinations thereof, to enhance the corrosion resistance of the resultant coating film. In one embodiment, the carbon pigment is a surface-modified carbon pigment. The coating compositions have good adhesion to substrates such as metals, including aluminum and aluminum alloys.Non-confidential Abstract of Invention: The present invention relates to aqueous or solvent borne paint compositions containing crystalline and amorphous carbon pigments, surface modified carbon pigments, surfactant dispersed carbon pigments, resin dispersed carbon pigments, and the like, or combinations thereof, having corrosion resistant properties with good adhesion to metals, including aluminum and aluminum alloys, bare and galvanized steel, zinc, magnesium and magnesium alloys, metal pretreatments, such as chrome-based conversion coatings, cobalt-based conversion coating, phosphate-based conversion coating, silica-based conversion coatings, rare earth-based conversion coatings, stainless metal pretreatments, and the like, and/or composites.
