Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Adipic Acid And Ethylenediamine is a polymeric amide resin derived from dimerized unsaturated C18 fatty acids, adipic acid, and ethylenediamine. This specialized polymer is valued for its excellent film-forming, adhesive, and hydrophobic properties, making it a crucial component in high-performance industrial coatings and inks. It is primarily used by formulators in the coatings, printing, and adhesive industries seeking to enhance product durability, gloss, and chemical resistance.

Application

• Primary component in high-gloss, chemically resistant industrial and protective coatings.
• Key resin for flexographic and gravure printing inks, providing excellent adhesion and rub resistance.
• Used as a modifier and film-forming agent in specialty adhesives and sealants.
• Employed in the formulation of overprint varnishes to improve surface protection and appearance.
• Serves as a rheology modifier and dispersing agent in pigment concentrates and masterbatches.
• Potential use in fiber sizing and textile finishing agents to impart water repellency.
