NOVELTY - Aqueous-based paint comprises 30-50 pts. wt. aqueous -based silicone modified polyurethane resin, 10-20 pts. wt. acrylic resin, 15-20 pts. wt. titanium dioxide, 1-3 pts. wt. titanate coupling agent, 1-3 pts. wt. graphene, 3-5 pts. wt. co-solvent, 0.1-0.5 pts. wt. wetting agent, 0.5-1 pts. wt. dispersant, 0.8-1.5 pts. wt. rheological additives, 0.5-1 pts. wt. aqueous-based crosslinking agent and 20-60 pts. wt. water. USE - The aqueous-based paint is useful for multiple substrates. ADVANTAGE - The paint: can avoid the rust problem caused by incomplete substrate treatment. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for preparing aqueous-based coatings for multiple substrates comprising (1) adding aqueous-based silicone modified polyurethane resin, acrylic resin, water-based crosslinking agent, and water into the agitator first, and stirring it evenly at a speed of 1000-1200 revoluitons/minute and (2) adding titanium dioxide, titanate coupling agent, graphene, co-solvent, wetting agent, dispersant, and rheological additive into the agitator, heating to 50-70 degrees C, ultrasonic treating with frequency of 700-800 kHz for 30-40 minutes and stirring evenly to obtain aqueous -based paint.
