Quality Control

Our Tetrakis-(4-isocyanatophenoxymethyl)-methane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, isocyanate content determination, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) 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 a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) to prevent reaction with atmospheric moisture and carbon dioxide. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
