Technical Document

Brief Overview

Gum Rosin Grade WW, or Water White Rosin, is a premium-quality resin derived from pine trees. The term "WW" signifies its water-white or pale yellow color, indicating a high level of purity. This grade is renowned for its clarity and transparency, making it a preferred choice in various industries.

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 Industry

Gum Rosin Grade WW is a crucial component in formulating adhesives for bonding applications in industries such as paper, wood, and packaging.

Ink Industry

Widely used in the production of printing inks, Gum Rosin Grade WW enhances adhesion strength and contributes to vibrant and clear colors.

Coatings Industry

In the coatings industry, Gum Rosin Grade WW is employed for its clarity and transparency, making it valuable in formulations for transparent coatings and layers requiring weather resistance.
