How plastic emulsion paint becomes water resistant after applying?

Water-based Polyurethane dispersions are a rapidly growing segment of the polyurethane coating industry to environmental legislations such as the clean air act or also due to technological advance. They are versatile and environmentally friendly coating materials that are available in a wide range of hardness and solid content. Their verstility and wide range of superior properties such as abrasion resistance, impact strength and low temperature flexibility are the driving forces to their continuously expanding usage in many applications.
