The performance and function of petroleum resin in different industries:

A. The paint mainly uses C9 petroleum resin, DCPD resin and C5/C9 copolymer resin with high softening point. Adding petroleum resin to the paint can increase the gloss of the paint, improve the adhesion, hardness, acid resistance and alkali resistance of the paint film.

B. Rubber mainly uses C5 petroleum resin, C5/C9 copolymer resin and DCPD resin with low softening point. Such resins have good mutual solubility with natural rubber particles, and have no great influence on the vulcanization process of rubber. Adding petroleum resin to rubber can increase viscosity, strengthen and soften. In particular, the addition of C5/C9 copolymer resin can not only increase the adhesion between rubber particles, but also improve the adhesion between rubber particles and cords. It is suitable for rubber products with high requirements such as radial tires.

C. The petroleum resin in the adhesive industry has good adhesion. Adding petroleum resin to the adhesive and pressure-sensitive tape can improve the adhesive force, acid resistance, alkali resistance and water resistance of the adhesive, and can Effectively reduce production costs.

D. Petroleum resins for inks in the ink industry are mainly high softening point C9 petroleum resins and DCPD resins. The addition of petroleum resin to the ink can play the role of color development, quick drying, brightening, and improve printing performance.

E. Coatings for road signs and road markings in the coating industry, petroleum resin has good adhesion to concrete or asphalt pavement, and has good wear resistance and water resistance, and has good affinity with inorganic substances, easy to coat, good weather resistance, fast drying, high firmness, and can improve the physical and chemical properties of the layer, improve UV resistance and weather resistance. At present, petroleum resin road marking paint is gradually becoming the mainstream, and the demand is increasing year by year.

F. Other resins have certain unsaturation and can be used as paper sizing agent, plastic modifier, etc.
