Description

3-[(4-Isocyanatocyclohexyl)Methyl]-o-Tolyl Isocyanate is a specialized aliphatic-aromatic diisocyanate monomer, a critical building block for high-performance polyurethane materials. Its unique molecular structure, featuring both a cyclohexyl and a tolyl isocyanate group, enables the synthesis of polymers with a superior balance of chemical resistance, mechanical strength, and weatherability. This compound is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop advanced, durable products.

Application

• High-Performance Polyurethane Coatings: Used as a crosslinker in automotive clear coats, industrial maintenance paints, and aerospace coatings for enhanced durability, gloss retention, and resistance to yellowing.
• Specialty Adhesives & Sealants: Serves as a key component in formulating structural adhesives, potting compounds, and flexible sealants that require strong bonding and environmental stability.
• Elastomer Production: Employed in the synthesis of cast, thermoplastic, and millable polyurethane elastomers for applications demanding high tensile strength, abrasion resistance, and low-temperature flexibility.
• UV-Curable Resins: Acts as a reactive intermediate in the production of urethane acrylates and other oligomers for fast-curing, low-VOC radiation-curable systems.
• Chemical Intermediate: Utilized in organic synthesis for the preparation of ureas, carbamates, and other derivatives with specific functional properties.
• Composite Materials: Incorporated into polyurethane matrices for fiber-reinforced composites, improving interfacial adhesion and overall material performance.

Quality Control

Every batch of 3-[(4-Isocyanatocyclohexyl)Methyl]-o-Tolyl Isocyanate is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards and customer-specific requirements. Comprehensive analytical testing, including assay, isocyanate content, and impurity profiling, is performed. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to guarantee traceability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and oxidation. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, acids, and water.
