Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Acetic Acid, Diethylenetriamine And Ethylenediamine is a complex, high-performance polyamide resin derived from unsaturated C18 fatty acid dimers and polymers, reacted with acetic acid and a blend of polyamines. This compound matters for its unique combination of film-forming, adhesive, and rheological modification properties, making it a versatile intermediate for demanding industrial formulations. It is primarily needed by manufacturers in the coatings, adhesives, and ink industries seeking to enhance product durability, flexibility, and chemical resistance.

Application

• Industrial Coatings & Paints: Acts as a reactive diluent, flexibilizer, and adhesion promoter in high-performance epoxy and polyamide curing agent systems for protective and marine coatings.
• Adhesives & Sealants: Used as a tackifier and rheology modifier in hot-melt, pressure-sensitive, and structural adhesives to improve bond strength and thermal stability.
• Printing Inks: Serves as a resinous component in solvent-based and overprint varnishes to enhance gloss, rub resistance, and substrate adhesion.
• Corrosion Inhibitors: Functions as a film-forming agent in protective coatings and oilfield chemicals to create a barrier against moisture and corrosive agents.
• Lubricant Additives: Employed as a viscosity index improver and anti-wear agent in synthetic and industrial lubricants.
• Foundry & Casting: Used in core and mold binders to improve sand cohesion and casting finish.
