Description

2-Isocyanato-4-[(2-Isocyanatocyclohexyl)Methyl]-1-Methylcyclohexane is a specialized aliphatic diisocyanate monomer, a key building block in the synthesis of high-performance polyurethane polymers. Its unique sterically hindered cycloaliphatic structure provides exceptional resistance to UV light and weathering, making it critical for applications demanding long-term durability and color stability. This product is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings: A primary component in automotive clear coats, industrial maintenance coatings, and aerospace finishes where superior gloss retention and resistance to yellowing are required.
• Light-Stable Elastomers: Used in the production of cast elastomers and thermoplastic polyurethanes (TPU) for outdoor applications, such as seals, gaskets, and industrial wheels.
• Advanced Adhesives & Sealants: Formulated into structural adhesives and high-grade sealants that maintain flexibility and bond strength under prolonged exposure to sunlight and harsh environments.
• UV-Curable Systems: Serves as a reactive intermediate in the development of UV-curable resins for inks, overprint varnishes, and 3D printing materials.
• Specialty Crosslinkers: Acts as a crosslinking agent for hydroxyl-functional resins, enhancing the chemical resistance and mechanical properties of the final polymer network.
• Optical and Electronic Materials: Utilized in the synthesis of polyurethane-based materials for optical lenses, encapsulants, and protective films in electronic devices.

Quality Control

Our production of 2-Isocyanato-4-[(2-Isocyanatocyclohexyl)Methyl]-1-Methylcyclohexane adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, isocyanate content, and impurity profile analysis, to ensure consistency and high purity. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

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 sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture and CO2.
