Description

Bis(Hexamethylene)Triamine CAS NO 143-23-7 is a high-purity, linear aliphatic triamine with versatile reactivity, serving as a critical building block in advanced polymer synthesis. Its trifunctional nature provides superior cross-linking and chain extension capabilities, making it essential for creating durable, high-performance materials. This compound is primarily sought after by manufacturers in the epoxy curing, polyamide resin, and corrosion inhibitor sectors.

Application

• Epoxy Curing Agent: A key component in formulating high-performance, room-temperature or heat-cured epoxy systems for coatings, adhesives, and composites.
• Polyamide Resin Production: Acts as a monomer for synthesizing Nylon-type resins and other specialty polyamides with enhanced thermal and chemical resistance.
• Corrosion Inhibitor Intermediate: Used in the manufacture of oilfield chemicals and industrial water treatment formulations to protect metal surfaces.
• Polyurethane Catalyst: Serves as a reactive catalyst or chain extender in the production of flexible and rigid polyurethane foams and elastomers.
• Chelating Agent Synthesis: A precursor for creating complexing agents used in detergents, pulp/paper processing, and metal ion sequestration.
• Textile & Leather Auxiliaries: Employed in the synthesis of softening agents, dye fixatives, and other functional textile chemicals.
• Pharmaceutical & Agrochemical Intermediates: Used in organic synthesis to introduce amine functionality into active molecules.

Quality Control

Our Bis(Hexamethylene)Triamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis via GC or HPLC, to ensure it meets precise specifications for amine value, color, and moisture content. A comprehensive Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed-upon standards. We support audits and can provide material for customer qualification.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This product is hygroscopic (moisture-sensitive) and a strong alkali; containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from heat, sparks, open flames, and strong oxidizing agents.
