Petroleum resin (hydrocarbon resin) is a thermoplastic resin produced from the C5 and C9 fractions produced by petroleum cracking through pre-treatment, polymerization, distillation and other processes. It is not a polymer, but a low molecular weight between 300-3000 Polymer.

Petroleum resin is named because it is derived from petroleum derivatives. It has the characteristics of low acid value, good miscibility, water resistance and chemical resistance. It is chemically stable against acids and bases, and has the characteristics of good viscosity adjustment and thermal stability.

Petroleum resin is generally not used alone, but as an accelerator, regulator, modifier and other resins.

Petroleum resin is a newly developed chemical product in recent years. It has the advantages of low price, good miscibility, low melting point and resistance to water and chemicals.It can be widely used in rubber, adhesives, coatings, paper, ink and other industries and fields.

Application of C9 cold poly petroleum resin

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

2.Rubber mainly uses low softening point C5 petroleum resin and C5/C9 copolymer resin DCPD resin. This type of resin has good mutual solubility with natural rubber particles: it has no major impact on the rubber vulcanization process. Adding petroleum resin to rubber can increase viscosity, reinforcement, and softening.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 sub-strands. It is suitable for rubber with high requirements such as radial tires.

3.The petroleum resin used in ink is mainly high softening point C9 petroleum resin DCPD resin.Adding petroleum resin to ink can develop color, dry quickly, brighten, and improve printing performance.

4.Petroleum resin has good adhesive properties. Adding petroleum resin to adhesives and pressure-sensitive tapes can improve the adhesive force, acid resistance, alkali resistance and water resistance of the adhesive, and can effectively reduce production costs.

5.As a coating for road signs and road markings, petroleum resin has good adhesion to concrete or asphalt pavement, good abrasion resistance and water resistance, good affinity with inorganic substances, easy coating, good weather resistance, Quick drying, high solidity.
It can also 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 mainstream, and the demand is increasing year by year.
