Polyurethane floor paint is polymerized from polyether polyol, polyisocyanate, chain extender and vulcanizer, filler, anti-aging agent, etc. Polyurethane floor paint is widely used in floor construction cases due to its excellent physical and mechanical properties, excellent wear resistance, excellent chemical resistance, weather resistance and UV resistance. Polyurethane resin is the main component of polyurethane floor paint, giving it excellent physical and chemical properties. Pigments and fillers are used to adjust the color and increase the physical properties of the coating. Solvents are used to adjust the viscosity and construction performance of the coating. Additives are used to improve the leveling, anti-precipitation and weather resistance of the coating.
