Description

Hexamethylenediamine (CAS NO 124-09-4) is a vital aliphatic diamine monomer, serving as a fundamental building block in the production of high-performance polymers. Its bifunctional nature, featuring two primary amine groups, makes it indispensable for creating strong, durable polyamide linkages. This chemical is essential for manufacturers in the polymer, coatings, and specialty chemical industries seeking to produce materials with excellent thermal and mechanical properties.

Application

• Nylon 6,6 Production: The primary industrial use, reacting with adipic acid to form the polyamide salt (nylon salt) for fibers, engineering plastics, and films.
• Polyurethane Catalysts & Chain Extenders: Acts as a curing agent and hardener in polyurethane systems, influencing foam properties and elastomer performance.
• Epoxy Resin Curing Agent: Used to cross-link and harden epoxy resins, enhancing chemical resistance and thermal stability in coatings and composites.
• Synthesis of Isocyanates and Diisocyanates: A key intermediate in the production of hexamethylene diisocyanate (HDI), a critical component for light-stable polyurethane coatings.
• Corrosion Inhibitors and Metal Treatment: Employed in formulations for metal surface treatment and as an intermediate for corrosion-inhibiting compounds.
• Agrochemical and Pharmaceutical Intermediates: Serves as a versatile building block in the synthesis of various active ingredients and specialty chemicals.
• Chelating Agents and Ion Exchange Resins: Used in the production of chelants for water treatment and as a monomer for certain ion-exchange resins.

Quality Control

Our Hexamethylenediamine is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, color, and moisture content. Our production adheres to relevant industry standards, and we support our global customers with the necessary regulatory documentation for their supply chains.

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 acids and oxidizing agents. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is between 15°C and 25°C.
