Description

1,6-Diisocyanatohexane is a key aliphatic diisocyanate monomer essential for the synthesis of high-performance polyurethane materials. Its primary value lies in providing excellent light stability, chemical resistance, and mechanical properties to the final polymer, making it superior to aromatic alternatives in applications requiring color stability and weatherability. This compound is critically needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing specialty polymers and cross-linking agents.

Application

• Light-Stable Polyurethane Coatings: A fundamental building block for aliphatic polyurethane dispersions (PUDs) and coatings used in automotive, aerospace, and industrial applications where resistance to yellowing and UV degradation is paramount.
• High-Performance Adhesives & Sealants: Used in formulating adhesives and sealants that require durability, flexibility, and resistance to environmental factors for construction, automotive assembly, and marine applications.
• Elastomers and Thermoplastic Polyurethanes (TPU): Serves as a core component in the production of elastic fibers, hoses, gaskets, and other molded parts that demand a combination of toughness and weatherability.
• Cross-linking Agent for Resins: Employed to cross-link hydroxyl-functional polymers, enhancing the hardness, chemical resistance, and overall performance of acrylic and polyester-based coating systems.
• Specialty Chemical Synthesis: Acts as a crucial intermediate in organic synthesis for creating ureas, biurets, and other derivatives used in further downstream chemical manufacturing.

Quality Control

Our 1,6-Diisocyanatohexane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical methods including chromatography and titration. A Certificate of Analysis (COA) detailing purity, isocyanate content, and key impurity profiles is provided with each shipment to ensure compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures recommended for diisocyanates (typically below 25°C). This material is hygroscopic (moisture-sensitive) and must be protected from atmospheric moisture to prevent polymerization and loss of activity. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and water.
