Description

1-Isocyanato-3-[(2-Isocyanatocyclohexyl)Methyl]-2-Methylcyclohexane is a specialized aliphatic diisocyanate monomer, a key building block in the synthesis of high-performance polymers. Its value lies in its unique cycloaliphatic structure, which imparts exceptional light stability, chemical resistance, and mechanical properties to the final polyurethane or polyurea products. This compound is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop advanced materials for demanding applications.

Application

• High-Performance Polyurethane Coatings: Used as a crosslinker in automotive clear coats, industrial maintenance paints, and coil coatings where superior weatherability, gloss retention, and resistance to yellowing are critical.
• Light-Stable Adhesives & Sealants: A key component in formulating adhesives and sealants for construction, aerospace, and automotive applications that require long-term durability under UV exposure.
• Specialty Elastomers: Serves as a monomer for producing cast, spray, or thermoplastic polyurethane/polyurea elastomers used in industrial rollers, mining screens, and protective linings.
• Advanced Composite Materials: Employed in the resin matrix for fiber-reinforced composites, enhancing the inter-laminar strength and environmental resistance of parts for transportation and marine industries.
• UV-Curable Systems: Can be incorporated into oligomers for radiation-curable coatings and inks, contributing to rapid cure speeds and excellent film properties.

Quality Control

Every batch of our 1-Isocyanato-3-[(2-Isocyanatocyclohexyl)Methyl]-2-Methylcyclohexane is manufactured and tested under a strict quality management system. We ensure the product meets high-purity standards suitable for demanding industrial and specialty chemical synthesis. Comprehensive testing includes assay, isocyanate content, hydrolyzable chloride, and color (APHA). A Certificate of Analysis (COA) documenting all critical parameters is provided with each shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
