Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylenediamine And Sebacic Acid is a high-performance polymeric amide derived from dimerized unsaturated C18 fatty acids, ethylenediamine, and sebacic acid. This specialized polymer offers unique properties such as excellent film-forming capability, adhesion, and chemical resistance, making it a valuable intermediate for demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance the durability and performance of their products.

Application

• Corrosion-Resistant Coatings: Acts as a key film-forming agent and adhesion promoter in high-performance industrial and marine protective coatings.
• High-Strength Adhesives & Sealants: Used as a polymeric backbone to improve flexibility, thermal stability, and bond strength in structural adhesives and sealants.
• Printing Inks: Serves as a resin component to enhance gloss, rub resistance, and substrate adhesion in specialty printing inks.
• Polymer Modification: Employed as an additive or co-reactant to modify the properties of other polymers, improving toughness and chemical resistance.
• Lubricant & Grease Additives: Functions as a thickener or performance additive to improve the viscosity index and extreme-pressure properties of lubricants.
• Textile & Leather Auxiliaries: Utilized in finishes and coatings to provide water repellency, softness, and durability to fabrics and leather goods.
