PZX-L is a new type of resin used in hot melt traffic marking paint. It can enhance the paint’s toughness, hardness and adhesion, to form a smooth surface; and by adding additive, it can make the resin stay in a stable condition during four seasons; also, it can mix well with the rosin resin. By mixing with high-end paint, it can make the paint film form water-resistant, UV resistant and chemical resistant characters, and can improve the surface’s brightness and drying property.
