1. What is Rosin?

Rosin Chemistry

Rosin is a solid transparent substance. Rosin mainly consists of abietic acid with general formulae of C20H30O2.

Solubility

While Rosin is insoluble in water, it is soluble in organic solvents like alcohol, benzene, chloroform, Turpentine oil, and other organic solvents.
It is hard at room temperature and is very sticky at high temperatures.

Melting and Flammability

The melting point varies as per grade but it is semi-fluid at 100 degrees Celsius. irrespective, its melting point varies from 120 to 170 degree Celsius. It becomes flammable at temperatures above 190 degrees Celsius, so proper care should be taken care at such high temperatures.

Chemical Composition of Rosin

 Abietic Acid – C20H30O2

3. Rosin Treatment & Its Derivatives

Most of the time it is not suitable to apply gum rosin directly in the manufacturing process, rather it is modified and then used as a raw material in industries. Modification of gum rosin is done by hydrogenation, esterification, polymerized and glycerol, and disproportionate.
We call Rosin Modification as Rosin-Derivatives. They have a wide use in many industries.

4. Rosin Derivatives & Their Specifications

In India, rosin is obtained as the residual solid matter in the distillation of oleoresin gum, exudate of Pinus roxbur ghii and other allied pines species grown in India. It is a natural organic compound, mainly composed of resin and is soluble in organic solvents.
It is an important raw material used in the manufacturing of paints and coatings, inks, rubber, soap, paper, electronic industrial products, and rosin-derivatives, etc.
