Petroleum resin CAS 64742-16-1 is named after its source of petroleum derivatives. It has low acid value, good miscibility, water resistance, ethanol resistance, and chemical resistance. It is chemically stable to acids and bases, and has the characteristics of good viscosity regulation and thermal stability. Petroleum resin is generally not used alone, but as a promoter, regulator, modifier, and other resins used together.

The performance and role of petroleum resin in different industries:

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

B. Rubber mainly uses low softening point C5 petroleum resin, C5/C9 copolymer resin, and DCPD resin. This type of resin has good compatibility with natural rubber particles and has no significant impact on the vulcanization process of rubber. The addition of petroleum resin to rubber can play a role in increasing viscosity, strengthening, and softening. Especially with the addition of C5/C9 copolymer resin, not only can the adhesion between rubber particles be increased, but also the adhesion between rubber particles and cord can be improved, making it suitable for high demand rubber products such as radial tires.

C. Petroleum resin in the adhesive industry has excellent adhesion. Adding petroleum resin to adhesives and pressure sensitive tapes can improve the adhesive strength, acid resistance, alkali resistance, and water resistance of adhesives, as well as effectively reduce production costs.

D. Petroleum resins are mainly used in the ink industry, including high softening point C9 petroleum resin and DCPD resin. Adding petroleum resin to ink can achieve color development, fast drying, brightening effects, and improve printing performance.

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

F. Other resins have certain unsaturated properties and can be used as paper adhesives, plastic modifiers, etc. 5、 Petroleum resin is a non hazardous material and should be protected from sunlight and rain during transportation; It cannot be transported together with spontaneous combustibles, strong oxidants, and strong acids. Petroleum resin should be stored in a ventilated, cool, and dry environment. The storage period is generally one year, and after one year, if it passes the inspection, it can still be used.
