Description

Fatty Acids, Tall-Oil, Polymers With Glycerol, Phthalic Anhydride And Rosin is a complex polymeric resin derived from renewable tall oil fatty acids, glycerol, phthalic anhydride, and rosin. This versatile alkyd-type polymer is engineered to provide excellent film-forming properties, adhesion, and chemical resistance for demanding industrial applications. It is a critical raw material for formulators in the coatings, adhesives, and ink industries seeking high-performance, sustainable resin solutions.

Application

• Industrial Coatings Binder: Used as a primary resin in air-drying and baking enamels for machinery, agricultural equipment, and metal primers, offering good durability and gloss.
• Printing Inks: Serves as a key component in gravure and flexographic inks, providing excellent pigment wetting, printability, and rub resistance.
• Adhesive Formulations: Acts as a tackifying and reinforcing agent in hot-melt and pressure-sensitive adhesives, enhancing bond strength and thermal stability.
• Varnishes and Overprint Lacquers: Imparts a hard, protective, and glossy finish to wood, paper, and other substrates.
• Caulks and Sealants: Contributes flexibility, adhesion, and weather resistance in construction and automotive sealant formulations.
