Description

(2,4,6-Trioxotriazine-1,3,5(2H,4H,6H)-Triyl)Tris(Hexamethylene) Isocyanate is a specialized, multi-functional aliphatic isocyanate monomer. This compound is valued for its ability to impart high-performance characteristics such as enhanced durability, chemical resistance, and weatherability to polymeric materials. It is primarily sought after by formulators and manufacturers in the advanced coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for the synthesis of specialty polymers and cross-linking agents.

Application

• As a key cross-linking agent in the production of high-performance, light-stable polyurethane coatings for automotive, aerospace, and industrial applications.
• In the formulation of advanced adhesives and sealants requiring excellent flexibility and resistance to environmental degradation.
• As a reactive monomer for synthesizing specialty polyisocyanurate foams with improved thermal and mechanical properties.
• For the manufacture of elastomers with enhanced resistance to oils, chemicals, and abrasion.
• In the creation of UV-curable resin systems for coatings and inks, leveraging its multi-functional reactivity.
• As a building block for dendrimers and hyperbranched polymers used in advanced material science.
• For surface modification of materials to introduce isocyanate functional groups for further chemical grafting.

Quality Control

Our (2,4,6-Trioxotriazine-1,3,5(2H,4H,6H)-Triyl)Tris(Hexamethylene) Isocyanate is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay, isocyanate content, viscosity, and color determination, to ensure it meets precise specifications for high-performance applications. Certificates of Analysis (COA) documenting full compliance are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
