Description

C18-Unsaturated Fatty Acids Dimers Polymers With Diethylene Glycol is a polymeric ester derived from the condensation of dimerized unsaturated C18 fatty acids with diethylene glycol. This specialized chemical is valued for its unique combination of hydrophobic character, flexibility, and film-forming properties, making it a versatile intermediate and functional additive. It is primarily utilized in the formulation of high-performance industrial lubricants, coatings, adhesives, and polymer modification. The CAS number for this compound is 68552-01-2.

Application

• Lubricant & Grease Additive: Acts as a viscosity modifier and tackifier in synthetic and semi-synthetic lubricants and greases, enhancing film strength and adhesion.
• Polymer Plasticizer & Modifier: Imparts flexibility and improves low-temperature properties to various polymers, including PVC, polyurethanes, and rubber compounds.
• Coating & Ink Resin Intermediate: Serves as a building block for alkyd resins and polyesters, contributing to improved gloss, adhesion, and water resistance in paints and printing inks.
• Adhesive & Sealant Formulation: Used as a component in hot-melt and pressure-sensitive adhesives to adjust rheology and enhance cohesive strength.
• Metalworking Fluid Component: Functions as a lubricity agent and corrosion inhibitor in coolants and drawing compounds.
• Textile & Leather Auxiliary: Employed as a softening agent and water-repellent finish for fibers and leather goods.
