Description

2-Ethyl-2-[[[[[(5-Isocyanato-1,3,3-Trimethylcyclohexyl)Methyl]Amino]Carbonyl]Oxy]Methyl]Propylene [(5-Isocyanato-1,3,3-Trimethylcyclohexyl)Methyl]Carbamate is a specialized, high-performance aliphatic diisocyanate derivative. This compound is engineered to serve as a critical building block in the synthesis of advanced polymers, offering enhanced stability and tailored reactivity. It is primarily sought after by R&D and production teams in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science for creating products with superior weatherability and mechanical properties.

Application

• High-Performance Polyurethane Coatings: A key raw material for formulating automotive clear coats, industrial maintenance paints, and aerospace coatings that require exceptional gloss retention, chemical resistance, and UV stability.
• Specialty Adhesives and Sealants: Used in the synthesis of polyurethane prepolymers for structural adhesives, flexible sealants, and laminating agents where durability and adhesion under harsh conditions are critical.
• Advanced Elastomers: Serves as a crosslinking agent in the production of cast elastomers, rollers, gaskets, and impact-absorbing materials that demand a combination of toughness and elasticity.
• UV-Curable Resin Systems: Incorporated into oligomers for radiation-curable coatings and inks, contributing to fast curing times and excellent surface hardness.
• Modified Isocyanate Crosslinkers: Acts as a reactive intermediate to create blocked isocyanates or other derivatives used in heat-activated curing systems for powder coatings and composites.
• Pharmaceutical & Agrochemical Intermediates: Utilized in the research and development of active ingredients and drug delivery systems that require specific, stable urethane linkages.

Quality Control

Our production of this advanced chemical intermediate adheres to strict quality management systems. Every batch is characterized using advanced analytical techniques including HPLC, GPC, and FTIR to ensure consistent composition, purity, and reactivity. A comprehensive Certificate of Analysis (COA) detailing assay, isocyanate content, viscosity, and color is provided with each shipment, ensuring full traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C/59-77°F) under a dry, inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and premature polymerization. Keep away from heat, open flames, and sources of ignition.
