1.Product Introduction：
C9 hydrocarbon petroleum resin is a kind of resin produced by C9 fraction,by products of petroleum cracking,through pretreatment,polymerization and distillation.It isn't a high polymer but a low polymer 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 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.
2.Application:
 A.paints
Paints mainly use C9 hydrocarbon petroleum resin with high softening points,C9 hydrocarbon resin added to paints can increase the final finishes of paints,the adhesiveness of paint films and the hardness.Resistance to acid and alkaline.
B.Rubbers
Mainly use C9 hydrocarbon petroleum resin with low softening points,the resin has very good mutual solubilities with natural rubber particles,No affect to the sulphurization of rubber.
C.Adhesives
The 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.
D.printing inks
Usually,C9 hydrocarbon petroleum resin which have high softening point are used for printing inks,they have color spreading,fast dry and brightening effects and will increase the printing property.
E.Others
C9 hydrocarbon petroleum resin has certain unsaturation property and can be used as paper glutting agents,plastic modifiers etc.
