Description

2-Isocyanato-4-[(4-Isocyanatocyclohexyl)Methyl]-1-Methylcyclohexane is a high-purity, aliphatic diisocyanate monomer, a critical building block for advanced polymer synthesis. Its value lies in its ability to impart superior light stability, chemical resistance, and mechanical properties to the resulting polyurethane and polyurea materials. This compound is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking durable, high-performance formulations.

Application

• High-Performance Polyurethane Coatings: Used in automotive clear coats, industrial maintenance paints, and aerospace coatings where exceptional UV resistance and color stability are required.
• Light-Stable Adhesives & Sealants: A key component in formulating adhesives and sealants for outdoor applications, construction, and automotive assembly that must resist yellowing.
• Specialty Elastomers: Serves as a core monomer for producing aliphatic polyurethane and polyurea elastomers used in rollers, gaskets, and wear-resistant parts.
• Advanced Composite Materials: Employed in the resin matrix for fiber-reinforced composites, enhancing durability and weatherability in marine and wind energy components.
• Optical and Electronic Encapsulants: Used in formulations for potting and encapsulating sensitive electronic or optical devices due to its purity and reliable curing profile.

Quality Control

Every batch of our 2-Isocyanato-4-[(4-Isocyanatocyclohexyl)Methyl]-1-Methylcyclohexane is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for high-purity chemical intermediates. A comprehensive Certificate of Analysis (COA) detailing purity, isocyanate content, and impurity profiles is provided with each shipment to guarantee consistent performance and reliability for your formulations.

Storage

Preserve in a tightly closed, moisture-proof 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 and moisture-sensitive nature, containers must be kept under a dry inert atmosphere (e.g., nitrogen or dry air) after opening to prevent polymerization and maintain product integrity.
