Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylene Glycol is a polymeric ester derived from the reaction of dimerized unsaturated C18 fatty acids with ethylene glycol. This specialized chemical serves as a versatile intermediate and functional additive, offering unique properties of viscosity modification, lubrication, and surface activity. It is essential for formulators and manufacturers in the coatings, lubricants, and polymer industries seeking to enhance product performance and processing characteristics.

Application

• Coatings & Inks: Acts as a rheology modifier, dispersing agent, and flow control additive in solvent-based and high-solids coatings, printing inks, and varnishes.
• Lubricants & Greases: Functions as a synthetic base oil component or thickener, providing excellent thermal stability, lubricity, and water resistance.
• Polymer Additives: Used as a plasticizer, processing aid, or compatibilizer in various polymer systems to improve flexibility and reduce melt viscosity.
• Adhesives & Sealants: Imparts tack, improves adhesion, and modifies the rheological profile of hot-melt and pressure-sensitive adhesives.
• Metalworking Fluids: Serves as a lubricity agent and corrosion inhibitor in synthetic and semi-synthetic metalworking formulations.
• Personal Care: Employed as an emollient and viscosity-increasing agent in cosmetic and personal care products like creams and lotions.
