Description

Fatty Acids, C18-Unsatd., Dimers, Tridecyl Esters is a high-performance synthetic ester derived from the dimerization of unsaturated C18 fatty acids and subsequent esterification with tridecyl alcohol. This chemical is valued for its excellent lubricity, thermal stability, and compatibility with a wide range of polymers and oils, making it a versatile functional additive. It is primarily sought by formulators in the lubricants, plastics, and coatings industries seeking to enhance product performance and durability.

Application

• As a synthetic lubricant base stock or performance additive in metalworking fluids, gear oils, and compressor lubricants.
• An effective plasticizer and processing aid for PVC and other polymers to improve flexibility and flow properties.
• A key component in the formulation of high-quality release agents and mold lubricants for rubber and plastic molding.
• Used as a corrosion inhibitor and friction modifier in industrial lubricant and grease formulations.
• Acts as a water-resistant agent and emollient in specialty coatings and cosmetic preparations.
• Employed as a compatibilizer and viscosity modifier in adhesives, sealants, and printing inks.

Quality Control

Our Fatty Acids, C18-Unsatd., Dimers, Tridecyl Esters are manufactured under a strict quality management system. Each batch is tested to ensure consistent chemical and physical properties, including acid value, saponification value, viscosity, and color. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong alkalis and organic solvents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
