Description

Trimethyl-1 6-Diisocyanatohexane is a high-purity aliphatic diisocyanate monomer, essential for producing advanced polymers with superior light stability and mechanical properties. This compound is critical for formulators requiring durable, non-yellowing materials for high-performance applications. It is primarily used by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in specialty polyurethane synthesis.

Application

• High-Performance Polyurethane Coatings: A key raw material for automotive clear coats, industrial finishes, and aerospace coatings that require exceptional weatherability and resistance to yellowing.
• Light-Stable Adhesives & Sealants: Used in formulating adhesives for outdoor applications, laminated glass, and construction sealants where long-term clarity and durability are paramount.
• Specialty Elastomers: Serves as a building block for elastomeric materials used in gaskets, rollers, and sports equipment that demand flexibility and color stability.
• UV-Curable Resins: Employed in the synthesis of resins for inks, 3D printing, and electronic encapsulants that cure rapidly under UV light.
• Crosslinking Agent: Functions as an effective crosslinker for hydroxyl-functional polymers, enhancing the chemical resistance and hardness of the final network.
• Medical Device Coatings: Used in the development of biocompatible, durable coatings for certain medical devices, subject to stringent purity requirements.

Quality Control

Our Trimethyl-1 6-Diisocyanatohexane is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standard of 99% minimum and consistent performance. Certificates of Analysis (COA) with detailed specifications are provided for full traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Isolate from strong bases, acids, alcohols, amines, and water.
