NOVELTY - A heavy-duty anticorrosive coating comprises primer, intermediate paint, topcoat and graphene dispersion slurry. The primer comprises main primer and primer curing agent. The intermediate paint comprises main intermediate paint and intermediate paint curing agent. The topcoat comprises main topcoat and topcoat curing agent. The primer curing agent, intermediate curing agent and topcoat curing agent comprises aqueous silicone epoxy curing agent, hydrophobic agent, polysilazane and purified water respectively. The main primer comprises water-based silicone epoxy resin, wetting dispersant, defoamer, leveling agent, anti-flash rust agent, corrosion inhibitor, active zinc powder, mica powder, hydrated magnesium silicate, fumed silica and purified water. The main intermediate paint comprises water-based silicone epoxy resin, wetting dispersant, defoamer, leveling agent, mica iron oxide, hydrated magnesium silicate, fumed silica and purified water. USE - Heavy-duty anticorrosive coating. ADVANTAGE - The anticorrosive coating uses small layer of graphene dispersion slurry to compensate for the defects of water-based coating.
