Description

trans-1,4-Cyclohexane Diisocyanate is a high-purity, aliphatic diisocyanate monomer essential for producing advanced polymers with superior light stability and mechanical properties. Its primary value lies in enabling the synthesis of high-performance, non-yellowing polyurethanes, coatings, and adhesives. This product is critical for manufacturers in the automotive, aerospace, and specialty coatings industries seeking durable, weatherable materials.

Application

• High-Performance Polyurethane Coatings: Used as a key raw material in the production of aliphatic polyurethane dispersions (PUDs) and coatings for automotive clear coats, industrial finishes, and exterior architectural applications, offering excellent UV resistance and non-yellowing characteristics.
• Specialty Adhesives and Sealants: Serves as a crosslinking agent in formulations requiring long-term durability, flexibility, and resistance to environmental degradation.
• Elastomers and Thermoplastic Polyurethanes (TPU): Employed in the synthesis of light-stable elastomers for automotive parts, gaskets, and industrial components that demand high performance under harsh conditions.
• Advanced Composite Materials: Used in the matrix resin for fiber-reinforced composites in aerospace and high-end sporting goods, contributing to lightweight and durable structures.
• UV-Curable Systems: Acts as a reactive intermediate in formulations for coatings and inks that cure rapidly under UV light, providing a hard, durable finish.

Quality Control

Our trans-1,4-Cyclohexane Diisocyanate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical testing, including assay by titration and isomer content by GC, to meet the stringent requirements of advanced polymer synthesis. A Certificate of Analysis (COA) detailing purity, isomer ratio, and impurity profiles is supplied with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 argon) to prevent reaction with atmospheric moisture and carbon dioxide, which can lead to polymerization or urea formation.
