C9 Petroleum Resin

C9 Petroleum Resin

Product Description: This product is made from cracked C9 raw material by thermal polymerization, it is yellow or light yellow granular solid, with good thermal stability, compatibility, water resistance, acid and alkali resistance.

Application: This product is mainly used as auxiliary in paint, rubber special adhesive, ink, printing and other industries.

What is C9 Hydrocarbon Resin?

C9 hydrocarbon resin is produced by C9 fraction by products of petroleum cracking through pretreatment, polymerization and distillation. It is a low polymer with the molecular weight between 300-3000.

It’s Featured by acid value, easy mutual solubilities, resistant to water, resistant to ethanol and chemicals.

It has a chemical stabilizing property to acid and alkaline, viscosity adjusting and thermal stabilizing. Generally the resins are not used independently but have to be used together with other kinds of resins as promoters, adjusting agents and modifiers.


Paint Industries

Paints mainly use C9 petroleum resin with high softening points, C9 petroleum resin can increase the gloss of paint and improve the adhesion and the hardness, anti-acid, alkaline- resistance, water-resistance.


C9 petroleum resins have very good adhesiveness, they can increase the adhesion of adhesives especially for hot-melt adhesive, pressure-sensitive adhesive, coating, etc.

Rubber and Tyre

Mainly use C9 petroleum resin with low softening point, these C9 resin has very good mutual solubilities with natural rubber particles, non-affect to the sulphurization of rubber.

Printing Ink

Usually use C9 petroleum resin with high softening point, they have color spreading, fast dry and brightening effects and will increase the printing properties.


C9 Petroleum resin has certain unsaturation property and can be used as paper glutting agents, plastic modifiers etc.
