Description

Dimer Acid, Hydrogenated is a high-purity, saturated dicarboxylic acid derived from the dimerization and subsequent hydrogenation of unsaturated fatty acids. This process yields a product with exceptional oxidative stability, color retention, and resistance to degradation, making it a superior intermediate for demanding applications. It is a critical raw material for industries requiring high-performance polyamides, synthetic lubricants, and corrosion inhibitors. Key sectors that rely on this specialty chemical include polymer manufacturing, industrial lubricant formulation, and the production of high-grade adhesives and coatings.

Application

• Primary monomer for the synthesis of high-performance, flexible polyamide resins (hot-melt adhesives, printing inks, and plastic modifiers).
• Key ingredient in formulating synthetic lubricants and greases, providing excellent thermal stability and low pour points.
• Manufacturing of corrosion inhibitors and metalworking fluid additives for enhanced surface protection.
• Production of epoxy curing agents and plasticizers for improved flexibility and durability in coatings and sealants.
• Intermediate for specialty esters used in cosmetics and personal care products as emollients and thickeners.
• Base material for alkyd resins in high-quality industrial and decorative paints.

Quality Control

Our Dimer Acid, Hydrogenated is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for acid value, color, and composition. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as dimer content, monomer/trimer levels, and iodine value. We adhere to relevant industry standards and our quality protocols are designed to ensure batch-to-batch consistency and reliability for your critical formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize exposure to moisture and air.
