Description

1-Isocyanato-3-[(4-Isocyanatocyclohexyl)Methyl]-2-Methylcyclohexane is a specialized aliphatic diisocyanate monomer, known for its unique cycloaliphatic structure that imparts enhanced light stability and chemical resistance to final polymers. This compound is a critical building block for synthesizing high-performance polyurethane and polyurea materials, offering superior weatherability and mechanical properties. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking durable, non-yellowing products for demanding applications.

Application

• High-Performance Coatings: A key raw material for light-stable, aliphatic polyurethane coatings used in automotive clear coats, industrial maintenance paints, and aerospace finishes.
• Advanced Adhesives & Sealants: Used to formulate durable, flexible, and chemically resistant polyurethane adhesives and sealants for construction, automotive assembly, and marine applications.
• Specialty Elastomers: Serves as a crosslinker in the production of high-grade polyurethane and polyurea elastomers for rollers, wheels, and impact-resistant components.
• Optical and Electronic Encapsulants: Employed in potting and encapsulation compounds where clarity, UV stability, and long-term durability are critical for protecting sensitive electronic or optical devices.
• Composite Materials: Acts as a reactive component in the resin matrix for fiber-reinforced composites, enhancing interlaminar strength and environmental resistance.
• Waterborne Polyurethane Dispersions (PUDs): Used to synthesize aliphatic PUDs for environmentally friendly, low-VOC coatings and finishes on textiles, leather, and plastics.

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). This product is hygroscopic (moisture-sensitive) and must be kept under a dry, inert atmosphere (e.g., nitrogen or dry air) to prevent reaction with atmospheric moisture, which can lead to polymerization and loss of reactivity. Keep away from heat, open flames, and sources of ignition.
