NOVELTY - A graphene-containing lubricating varnish comprises 12-32 wt.% binder, 0.5-5 wt.% co-binder, 4-10 wt.% solid lubricant, 0.5-10 wt.% graphene, 0.1-2.0 wt.% additives and remainder of solvent. USE - Graphene-containing lubricating varnish is used for coating metallic materials, composite materials, aluminum, aluminum alloys, steel, stainless steel, cast iron materials, non-ferrous metals, plastics and polymers (all claimed). Uses include but are not limited to engine pistons, compressor pistons, compressor screws, coupling sleeves, bearing cage for ball/roller bearings, ball pivot, plain bushings, steering rods, rotors, springs, etc. ADVANTAGE - The graphene-containing lubricating varnish has improved hardness, wear resistance and friction characteristics.
