Water-based polyurethane floor coatings refer to paints formed by dissolving or dispersing polyurethane in water, characterized by coatings containing a significant number of urethane bonds. They primarily use polyurethane resin as the film-forming substance, combined with pigments, solvents, catalysts, and other auxiliary materials. These coatings exhibit wear resistance, water resistance, and excellent adhesion, making them suitable for tennis courts, standard running tracks, and similar applications.
