Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylenediamine, Hexamethylenediamine And Triethylenetetramine, Benzoates Propionates is a high-performance, multi-functional polymer derived from unsaturated C18 fatty acid dimers and polyamines, further modified with benzoate and propionate groups. This complex chemistry provides a unique combination of film-forming, emulsifying, and corrosion-inhibiting properties, making it a critical additive in demanding industrial formulations. It is essential for manufacturers seeking to enhance the durability, stability, and protective characteristics of their products across coatings, lubricants, and metalworking fluids.

Application

• Corrosion Inhibitors: A key component in formulating high-performance rust preventatives and corrosion inhibitors for metalworking fluids, industrial lubricants, and protective coatings.
• Lubricant Additives: Functions as an extreme pressure (EP) additive, friction modifier, and stabilizer in synthetic and semi-synthetic lubricants and greases.
• Coatings & Paints: Acts as a dispersing agent, flow modifier, and cross-linking component in industrial paints, varnishes, and epoxy coating systems to improve adhesion and chemical resistance.
• Metalworking Fluids: Used in soluble oils and synthetic coolants to provide lubricity, emulsion stability, and protection against tool wear and rust.
• Adhesives & Sealants: Serves as a tackifier and rheology modifier to improve the bonding strength and application properties of various adhesive formulations.
• Fuel & Oil Additives: Employed as a detergent and dispersant additive in fuel and lubricant packages to keep engines clean and improve performance.
• Polymer Modification: Used as a curing agent or chain extender to modify the properties of polyamides, polyurethanes, and other polymers.
