Compatibility of Gum Rosin with Different Industrial Applications

Rosin goes by the name colophony ("resin from Colophon") or Greek pitch. Rosin is a solid form of resin that is sourced from pines and other plants, such as conifers. Fresh liquid resin is heated to eliminate the volatile liquid terpene components in rosin production. The gum rosin contains the residue from distillation of oleoresin from pine trees.

Rosin consists of several resin acids, especially abietic acid and has various colours, from the range yellow to black. The darker colour of rosin is usually called wood rosin, sourced from the solvent extraction of the stumps. Gum rosin has a semi-transparent appearance and a faint pinelike odor. This resin could become sticky when it's warm, because when at stove-top temperature rosin will melt.

The production of gum rosin is mainly from Indonesia, Southern China, Brazil, and the northern part of Vietnam. The major rosin suppliers are the People's Republic of China, Indonesia, and Portugal, so the future supply of this resin depends on the production in those countries. The use of gum rosin in industrial is diverse, this resin could be used in crude raw material figure or even in modified form. Paper manufacturing, soap industries, and lubrication oil are some typical applications of the crude raw material rosin. While the modified gum rosin contains a mixture of abietic and primary acids plus a small number of neutral compounds.

Food Stuff IndustryGum rosin is an ingredient for producing chewing gum. Hydrogenated rosin is the type of rosin that is used for producing gum rosin. It is a dominant variety from modified rosin that has a light color. Not only to produce chewing gum, rosin could also be used as an emulsifier, and could be a density adjustment agent for flavouring oils in beverages.

Paints and Coating IndustryFor the paint industry, rosin is the most common basic material. Rosin is highly soluble in organic solvents such as gasoline, turpentine thus it is widely used in paint industries. Rosin is used to produce various lacquers. Rosin can be converted into Lacquers by firstly converting it into resonate and refine it with dry oil and followed by mixing with volatile solvent.

Metal Processing IndustryIn the metal processing industry, rosin is used for soldering aid and metal polishing agent. Since rosin has a weak acidity matter, it could be useful for removing the oxidation film from metal surface and could erode the surface of the metal. Thus the reason why lots of soldering aid agents contain rosin.

Papermaking IndustryThe application of rosin is mostly found in the papermaking industry. Rosin played a great role as a paper sizing agent. The advantages of using rosin paper sizing agents are: rosin could prevent printing oil soaking and dispersing from the paper, it could improve the strength and smoothness of paper.

Synthetic Rubber IndustryDisproportionated rosin or DPR is the most common form of rosin that plays a major role in the synthetic rubber industry. DPR is used as the emulsifier in the production, making the improvement in the cohesion of rubber products. Making the supplier of synthetic rubber could increase their product's quality.
