NOVELTY - Aqueous amino stoving varnish comprises 30-40 wt.% aqueous based polyester resin, 1.5-2 wt.% solvent, 10-12 wt.% co-solvent, 0.3-0.6 wt.% defoamer, 2-3 wt.% dispersant, 2-4 wt.% carbon black, 0.3-0.5 wt.% wetting agent, 0.3-0.5 wt.% leveling agent, 1-2 wt.% adhesion promoter, 6-8 wt.% melamine resin, 0.4-0.6 wt.% graphene and remaining amount of deionized water. USE - The stoving varnish is useful in surface coatings for special devices e.g. high-temperature flue gas ducts. ADVANTAGE - The stoving varnish has high temperature resistance, quick heat dissipation, strong corrosion resistance and strong adhesion and toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aqueous amino stoving varnish comprising (a) mixing aqueous polyester resin, solvent, 1/2 of co-solvent, dispersant, carbon black, leveling agent, adhesion promoter, melamine formaldehyde resin, graphene and deionized water are uniformly to obtain a mixture, (b) adding defoamer and wetting agent to the remaining 1/2 of co-solvent, stirring and adding mixture to obtain a slurry and (c) adding the slurry into a oscillator and oscillating to a fineness of /~15 mu m to obtain an aqueous amino stoving varnish.
