Description

Cyclohexane, 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethyl-, Trimer is a specialized, high-performance aliphatic polyisocyanate trimer derived from isophorone diisocyanate (IPDI). This compound matters for its excellent weatherability, light stability, and chemical resistance, making it a critical building block for durable, high-quality coatings and adhesives. Industrial formulators and chemical manufacturers in the coatings, elastomer, and specialty polymer sectors need this product to develop advanced polyurethane systems that require superior performance under demanding environmental conditions.

Application

• High-Performance Coatings: A key crosslinking agent in automotive clear coats, industrial maintenance paints, and coil coatings where exceptional UV resistance and gloss retention are paramount.
• Light-Stable Polyurethane Dispersions (PUDs): Used in the synthesis of aqueous polyurethane dispersions for wood, plastic, and textile coatings that require non-yellowing properties.
• Specialty Adhesives & Sealants: Imparts durability and flexibility in high-end construction, automotive, and aerospace adhesive formulations.
• Elastomers and Casting Resins: Serves as a hard segment component in the production of light-stable, abrasion-resistant polyurethane elastomers for technical parts.
• UV-Curable Systems: Incorporated as a reactive oligomer in radiation-curable coatings and inks to enhance mechanical properties and chemical resistance.
• Powder Coatings: Used in the formulation of exterior-grade powder coatings for architectural aluminum and automotive accessories.

Quality Control

Our Cyclohexane, 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethyl-, Trimer is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including NCO content determination, viscosity, color, and monomer content analysis. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to guarantee compliance with your formulation requirements.

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 (moisture-sensitive) nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent reaction with atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and water.
