Description

Oxydiethylene [4-[(4-Isocyanatocyclohexyl)Methyl]Cyclohexyl]-Carbamate is a specialized cycloaliphatic diisocyanate derivative, serving as a crucial building block for high-performance polymers. This compound is valued for its ability to impart enhanced light stability, chemical resistance, and mechanical properties to final materials. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced polyurethane and polyurea formulations.

Application

• High-Performance Polyurethane Coatings: Used as a crosslinker in formulations requiring exceptional weatherability, gloss retention, and resistance to yellowing, ideal for automotive topcoats and industrial maintenance paints.
• Light-Stable Adhesives & Sealants: A key component in the synthesis of polyurethane prepolymers for adhesives and sealants used in outdoor or UV-exposed applications.
• Specialty Elastomers: Employed in the production of cast elastomers and thermoplastic polyurethanes (TPU) that demand a balance of flexibility, toughness, and durability.
• Advanced Composite Materials: Functions as a reactive modifier in resin systems for composites, enhancing interfacial adhesion and overall performance.
• Pharmaceutical & Agrochemical Intermediates: Serves as a versatile intermediate in the synthesis of more complex molecules for active ingredient development.

Quality Control

Our Oxydiethylene [4-[(4-Isocyanatocyclohexyl)Methyl]Cyclohexyl]-Carbamate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, reactivity, and performance. Certificates of Analysis (COA) detailing key parameters such as isocyanate content, viscosity, and color are provided and available upon request to support your quality assurance protocols.

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) after initial opening to prevent degradation and maintain product integrity.
