      Purpose      1. Tire and rubber: the tire and rubber mainly uses coumarone resin of low softening point. Such resin has good intersolubility with colloidal particle of natural rubber, and it has no various effect on rubber vulcanizing process. When putting it in tire and rubber, this coumarone resin has the effect of viscosifying, reinforce and softening.   2. Oil paint: Oil paint mainly uses coumarone resin with high softening point.Glossiness of oil paint can be increased if putting this resin in oil paint, and meanwhile, it can increase adhesion, hardness, acidproof, and alkali proof of paint film. 3. Printing ink industry: Coumarone resin used in printing ink, is mainly resin with high softening point.        Packaging & Shipping  1. 25 kg plastic woven bag. 2. In 10 working days after receiving the prepayment or L/C
