Product Description

Rosin is a non - volatile natural resin obtained from pine resin through different processing methods7. It is an important chemical raw material widely used in various industries7.

 

In the soap industry, rosin is cooked with soda ash or caustic soda to make rosin soap, which has good detergency, easy solubility in water, oil - dissolving property, and is easy to foam. In the papermaking industry, rosin and caustic soda are used to make rosin sodium soap, which is mixed with paper pulp and alum to improve the strength, smoothness, and water resistance of paper. In the paint and coating industry, rosin is easily soluble in various organic solvents and can form a film with luster, which makes the paint bright in color, dry quickly, and have a smooth film appearance. In the ink industry, rosin is mainly used as a color carrier to make inks more adhesive to paper. In the adhesive industry, based on rosin esters and hydrogenated rosin esters, adhesives are commonly used as hot - melt adhesives, pressure - sensitive adhesives, and rubber tackifiers. In the rubber industry, rosin is used as a softener to increase its elasticity, and disproportionated rosin potassium soap can be made into synthetic rubber. In the food industry, glycerides of hydrogenated rosin are used to make chewing gum, and a mixture of rosin and cottonseed oil is used as a hair remover. In the electrical industry, rosin is used to make insulating oil and insulating varnishes. In the building materials industry, rosin is used as a concrete foaming agent, floor tile adhesive, and binder for vinyl chloride asbestos tiles. In addition, rosin is also used as a flux in electronic welding to remove the oxide film on the metal surface.
