Synonym: Petroleum Resin C9

Molecular Weight: 74.92

CSA NO.: 68131-77-1

Specification:

Properties: C9 Petroleum resin is a kind of thermal plasticizing resin produced by C9 fraction,by-products of petroleum cracking, through pretreatment,polymerization and distillation, It is not a high polyer bat a low polyjer with the molecular weight between 300-3000. Featared by acid value, easy mutual solubilities, resistant to water, resistant to ethanol and chemicals. It has the chemical stabilizing propety to caid and alkaline, viscosity adjusting and thermal stabilizing. Generally ,the petroleum resins are used together with other kings of resins as promoters, adjusting agents and modifiers.

Usage:

- Paints: Paints mainly use C9 petroleum resins with high softening points, petroleum resins areadded to paints can increase the final finishes of paints, the adhesiveness of paint films and the hardness. Resistance to acid and alkaline. - Rubbers: Mainly use C5 petroleum resins with low softening points ,these kinks of resins have very good mutual solubilities with natural rubber particles, No affect to the sulphurzation of rubber. Rubbers added with pertroleum resins will increase the strength, adhesiveness and softening property. - Adhesives: Petroleum resins have very good adhesiveness, they can increase the adhesiveness of adhesives, resistance to acid, alkaline and water. Subsequently they will reduce the production cost. - Printing inks: Usually, The C9 petroleum resins with high softening point are used for printing inks, they have color spreading, fast dry and brightening effects and increase the printing property. - Others: Petroleum resins have certain unsaturation property and can be used as paper glutting agent, plastic modifiers etc.

Storage:

Petroleum resins are non-hazardous products , however the direct sunshine and rain shall be avoided daring transportation, They can not be transported together with self-flammable materials, Strong Oxidizers and strong acid. Petroleum resins shall be stored in dry and cool area, the storage period is one year, but they can be used again if they out still up to specifications by inspection after one gear.
