Description

Isocyanatocyclohexane is a versatile aliphatic isocyanate monomer, a key building block for high-performance polymers. Its primary value lies in its ability to impart light stability, chemical resistance, and durability to polyurethane and polyurea coatings, adhesives, and elastomers. This product is essential for manufacturers in the coatings, automotive, and specialty chemical industries seeking to enhance product longevity and performance under demanding environmental conditions.

Application

• Light-Stable Polyurethane Coatings: Used as a crosslinker in automotive clear coats, industrial maintenance paints, and exterior wood finishes to prevent yellowing and degradation from UV exposure.
• High-Performance Elastomers: A key component in the synthesis of polyurethane and polyurea elastomers for applications requiring flexibility, abrasion resistance, and chemical stability.
• Adhesives and Sealants: Serves as a curing agent in formulations for construction, automotive assembly, and aerospace, providing strong bonds and environmental resistance.
• Specialty Chemical Intermediates: Acts as a precursor for synthesizing agricultural chemicals, pharmaceutical intermediates, and other fine chemicals requiring the cyclohexyl isocyanate functional group.
• Waterborne Polyurethane Dispersions (PUDs): Employed in the development of environmentally friendly coating systems with low volatile organic compound (VOC) content.
• Corrosion-Resistant Primers: Formulated into protective coatings for metal substrates in marine, infrastructure, and oil & gas applications.

Quality Control

Our Isocyanatocyclohexane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis by gas chromatography (GC), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its hygroscopic and 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.
