C9 Hydrocarbon Resin is a kind of Aromatic Hydrocarbon 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. Featured 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.
Paints mainly use C9 Hydrocarbon 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.
Mainly use C9 Hydrocarbon Resin with low softening points, the
resin has very good mutual solubilities with natural rubber
particles, No affect to the sulphurization of rubber.
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.
Usually, C9 Hydrocarbon 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.
C9 Hydrocarbon Resin has certain unsaturation property and can be
used as paper glutting agents, plastic modifiers etc.
