Applications:
A. Paints Industry: In paint industry mainly use the high softening point of C9 aromatic hydrocarbon resin which can increase the gloss of paint and improve the adhesion, the hardness and the resistance ability of ac id and alkali.
B. Tire and Rubber Industry:
Natural rubber particles, and little affect on rubber vulcanization. Adding in rubber and tires, C9 aromatic hydrocarbon resin can increase the adhesion and the reinforcement and can also play as softener.
C. Adhesives Industry:
C9 aromatic hydrocarbon resin has good adhesion, added in the process of producing adhesives and pressure-sensitive adhesives can improve the adhesive bond strength, acid resistance, alkali resistance and water resistance, and also can reduce production costs effectively.
D. Ink Industry:
In ink industry, mainly use the high softening point of C9 aromatic hydrocarbon resin which can reach the effect of show color, quick-drying and brightening and improve printing performance, etc.
E. others, C9 aromatic hydrocarbon resin has unsaturated certain characteristic, can be used as paper glue, plastic modifier etc
Resins Characters:
C9 aromatic hydrocarbon resin is a petroleum by-product of pyrolysis C9 fraction which is produced by pre-treatment, polymerization and distillation processes. It is not a high polymer but a low polymer molecular weight between 300-3000.
•Light colored granule
•low acid value, good miscibility, water,ethanol and chemical resistance, the chemical stability against acid, the good adjustment of viscosity and thermal stability.
•Generally, C9 aromatic hydrocarbon resin is not used alone, but as promoters, regulators, modifiers used with other resin.
