It is a thermoplastic, light yellow, low molecular weight, aliphatic resin. It provides excellent balance of tack, peel strength and cohesive strength, combined with light colour, low odour, and low volatility. In addition, it possesses low melt viscosity, low specific gravity, and good colour stability at compounding temperatures.
C5 petroleum resin is wildly used in the hot melt road paint industry, which can enhance the tenacity, rigidity and adhesive force of dope and form smooth paint surface, and also ensures the stable state of the resin in all seasons, and have a better mixing with rosin-like resin by adding auxiliary agent. In the mixing of top grade paint, it can form such features as water-proof, anti-ultraviolet radiation, anti-chemicals, and improve the brightness and dryness of the surface.
