Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylenediamine And Oleic Acid is a high-performance, polymeric fatty acid amide derived from unsaturated C18 fatty acid dimers and ethylenediamine, with oleic acid as a modifier. This specialized chemical offers exceptional performance as a rheology modifier, gelling agent, and corrosion inhibitor in demanding industrial formulations. It is essential for manufacturers in the lubricants, coatings, adhesives, and construction chemical industries seeking to enhance product stability, texture, and protective properties.

Application

• Lubricant & Grease Thickener: Acts as a primary or secondary thickener and structure modifier in lithium complex and other multipurpose greases, providing excellent thermal stability and water resistance.
• Corrosion Inhibitor: Used in metalworking fluids, industrial lubricants, and protective coatings to form a protective layer on metal surfaces, preventing rust and oxidation.
• Rheology Modifier for Coatings & Inks: Imparts thixotropic properties to solvent-based and high-solid coatings, printing inks, and adhesives, controlling sag and improving application characteristics.
• Adhesive & Sealant Component: Functions as a tackifier and rheology control agent in hot-melt adhesives, construction sealants, and caulks.
• Asphalt Modifier: Enhances the cohesion, elasticity, and aging resistance of asphalt binders used in road construction and roofing materials.
• Foundry Sand Binder: Serves as a core binder component in the foundry industry for mold and core making.
