Description

Cyclohex-1,4-Ylene Diisocyanate is a specialized aliphatic diisocyanate monomer used as a critical building block in high-performance polymer synthesis. Its rigid cyclohexane backbone imparts exceptional durability, chemical resistance, and low color to the resulting materials. This compound is essential for manufacturers in the coatings, adhesives, and specialty elastomers industries seeking to enhance product longevity and performance under demanding conditions.

Application

• High-Performance Polyurethane Coatings: A key raw material for producing light-stable, yellowing-resistant polyurethane coatings for automotive, aerospace, and industrial applications.
• Specialty Adhesives and Sealants: Used in formulating adhesives with superior bonding strength, flexibility, and resistance to moisture and chemicals.
• Elastomers and Castables: Serves as a crosslinker in the production of durable elastomers for gaskets, rollers, and other mechanical parts requiring toughness.
• UV- and Weather-Resistant Finishes: Integral to coatings for outdoor structures, wind turbine blades, and marine environments where long-term weatherability is critical.
• Advanced Composite Materials: Employed in the matrix resin systems for fiber-reinforced composites used in high-tech industries.

Quality Control

Our Cyclohex-1,4-Ylene Diisocyanate is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical methods including chromatography and titration. A Certificate of Analysis (COA) detailing specific results for purity, isocyanate content, and impurity profiles 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). 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 or gelation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
