Technical Document

Brief Overview

Gum rosin, also known simply as rosin, is a natural resin obtained from pine trees, primarily those belonging to the genus Pinus. This resin is derived from the sap or oleoresin of the pine tree, which is obtained by making incisions in the bark. The most common species used for gum rosin extraction include the slash pine (Pinus elliottii) and longleaf pine (Pinus palustris).

Manufacturing Process

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 160°C, 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.

Adhesives and Glues

Rosin serves as a crucial ingredient in the formulation of adhesives and glues, providing tackiness and adhesion properties.

Ink Production

It is used in the manufacturing of printing inks, acting as a binding agent that enhances the viscosity and printing qualities of the ink.

Coatings and Varnishes

Gum rosin is a common component in the production of coatings and varnishes, contributing to the adhesion and gloss of the final product.

Rubber Compounding

In the rubber industry, rosin derivatives are employed in the compounding process, enhancing the properties of rubber products.

Paper Sizing

Rosin is used in the sizing of paper, contributing to water resistance and improving the printing characteristics of paper.
