Gum Rosin

Gum rosin is an organic compound of monoterpene, turpentine and resin acid. Also known as colophony or rosin, it is a solid form of pine oleoresin from pine trees (mostly conifers). It is produced by heating fresh liquid resin in order to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from pale yellow to amber. Rosin is brittle at room temperature, but melts at higher temperatures. It is insoluble in water and soluble in organic solvents. Gum Rosin also has a faint piny odour. It consists mostly of different resin acids, especially abietic acid.

Gum Rosin

Gum Rosin can be found in Indonesia where it is derived from the distillation of Oleo Pine Resin. Different grades of gum rosin like WW, WG and X grade are available. Gum Rosin is also found in China where they are also produced from Oleo Pine Resin. The species of pine tree include P.massoniana, P.yunnanenisis P.meskussi and P.elliottii

Manufacturing Process

Gum Rosin

Gum Rosin is produced from the crude pine resin collected from pine trees. The resin is subjected to distillation and the distillation process is carried out in large copper stills. The volatile liquid terpene components would separate from the mixture as it vaporizes at a temperature between 100 to 160⁰C, leaving behind fluid rosin as the distillate. This fluid rosin is collected and purified by passing it through straining wadding. The condensate left behind is called turpentine oil.

Application and Use

Gum Rosin

Driven by the idea of providing top-quality Gum Rosin for our customers, we at Tradeasia International aim to organize and offer top-notch Gum Rosin that is widely used in several industries such as:

      • Electrical Product Industry, as an insulation material in electric equipment, cables, electric loop.
      • Metal Producing Industry, as a polishing agent because it can remove the oxidation films because of the weak acidity.
      • Adhesive and Sealants Industry, as an ingredient to enhance the strength, plasticity, and viscosity.
      • Paint and Coating Industry, because of the quality to dissolve easily in solvents such as turpentine, gasoline, and alcohol.
      • Paper Industry, as a sizing agent to improve the anti-abrasion.
      • Soap Production Industry, as a part of the grease because of the similar characters with fatty acid Synthetic rubber industry to enhance the plasticity, strength, flexibility, heat resistance.
      • Food Industry is using in the production of chewing gum after the conversion in hydrogenated.


Gum Rosin is an agricultural product that is distilled with pine trees. The color of the gum rosin was determined based on the standard Lovibond color which was classified according to its class XB, X, WW, and WG. The color difference is shown in the following image.
