C9 Hydrocarbon Resin, a type of aromatic resin, is a petroleum by-product of pyrolysis. C9 fraction, is produced by means of pre-treatment, polymerization and distillation processes. Key characteristics include low acid value; good miscibility; chemical stability against acid, ethanol, water, chemical resistance along with optimal adjustment of thermal stability and viscosity. Wide compatibility with different polymers and resins makes the series an excellent multi-purpose product. In appearance, C9 flake Petroleum Resin is a combination of yellow to dark brown color.The major application areas are paints and varnishes, printing inks, adhesives, rubber and elastomers, etc.
