Description

Rosin, Polymer With Glycerol And Tung Oil is a specialized modified rosin ester, produced by the polymerization of rosin with glycerol and tung oil. This chemical modification imparts enhanced thermal stability, improved adhesion, and excellent water resistance, making it a critical performance additive. It is primarily used in the formulation of high-performance industrial coatings, adhesives, and ink vehicles where durability and specific rheological properties are required.

Application

• Industrial Coatings: A key resin component in protective and decorative coatings for metal, wood, and plastic, providing excellent gloss, hardness, and chemical resistance.
• Adhesives & Sealants: Used as a tackifier and modifier in hot-melt, pressure-sensitive, and structural adhesives to enhance bond strength and flexibility.
• Printing Inks: Serves as a vital resin vehicle in gravure, flexographic, and lithographic inks, contributing to pigment wetting, gloss, and print fidelity.
• Rubber Compounding: Acts as a processing aid and tackifier in rubber products, improving compound viscosity and adhesion between plies.
• Polymer Modification: Employed to modify the properties of other polymers, improving compatibility, toughness, and adhesion to various substrates.
