Description

3,3',3''-[(1H,3H,5H)-2,4,6-Trioxo-1,3,5-Triazine-1,3,5-Triyltris(Methylene)]Tris[3,5,5-Trimethylcyclohexyl] Triisocyanate is a specialized aliphatic polyisocyanate monomer derived from isocyanuric acid and isophorone diisocyanate (IPDI). This compound is engineered to provide enhanced weatherability, light stability, and chemical resistance in high-performance polymer systems. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to develop durable, color-stable end products.

Application

• High-Performance Coatings: As a crosslinking agent in automotive clear coats, industrial coatings, and coil coatings where exceptional UV resistance and gloss retention are required.
• Advanced Polyurethane Adhesives & Sealants: Used to formulate adhesives with superior bonding strength, flexibility, and resistance to environmental degradation.
• Light-Stable Elastomers: Serves as a key component in the production of aliphatic polyurethane elastomers for outdoor and demanding applications.
• Specialty Resins for Composites: Employed in resin formulations for fiber-reinforced plastics (FRP) and composite materials that require long-term durability.
• UV-Curable Systems: Acts as a reactive diluent or crosslinker in radiation-curable inks, coatings, and 3D printing resins.
• Waterborne Polyurethane Dispersions (PUDs): Utilized to synthesize PUDs with improved hydrolytic stability and mechanical properties for eco-friendly coatings.

Quality Control

Our production of 3,3',3''-[(1H,3H,5H)-2,4,6-Trioxo-1,3,5-Triazine-1,3,5-Triyltris(Methylene)]Tris[3,5,5-Trimethylcyclohexyl] Triisocyanate adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including isocyanate content, viscosity, color, and monomer content to meet precise customer specifications. A comprehensive Certificate of Analysis (COA) documenting purity, physical properties, and safety data is provided with every shipment.

Storage

Preserve in a tightly closed 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). 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 gelation or loss of reactivity. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and water.
