Quality Control

Our production of this high-purity isocyanate adheres to stringent quality control protocols to ensure batch-to-batch consistency and reliability for sensitive polymer formulations. Every lot is characterized using advanced analytical techniques including HPLC, FT-IR, and titration to confirm identity, purity, and isocyanate content. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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, which can lead to polymerization or formation of solid urea derivatives. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, acids, and water.
