Description

Fatty Acids, Tall-Oil, Polymers With Isophthalic Acid, Linseed Oil And Trimethylolpropane CAS NO 68991-79-7 is a specialized polymeric resin synthesized from renewable tall oil fatty acids, isophthalic acid, linseed oil, and trimethylolpropane. This unique formulation provides an excellent balance of flexibility, adhesion, and chemical resistance, making it a valuable component in high-performance industrial coatings and inks. It is primarily sought after by manufacturers in the protective coatings, graphic arts, and adhesive industries seeking sustainable, high-quality resin solutions.

Application

• Protective & Industrial Coatings: Used as a key resin in alkyd formulations for metal primers, maintenance paints, and marine coatings, offering excellent corrosion resistance and durability.
• Printing Inks: Serves as a binder in high-gloss, quick-setting offset and lithographic inks, providing superior pigment wetting and rub resistance.
• Adhesives & Sealants: Imparts flexibility and strong substrate adhesion in formulated adhesives and mastic compounds.
• Wood Finishes: A component in varnishes and wood stains, enhancing penetration, drying time, and final film hardness.
• Corrosion-Resistant Linings: Formulated into heavy-duty linings for tanks, pipes, and structural steel in aggressive environments.
• Overprint Varnishes: Used to create protective, glossy topcoats for packaging and printed materials.
