Quality Control

Our production of Isocyanic Acid, 2,4,6-Triisopropyl-m-Phenylene Ester, Polymer With 1,12-Octadecanediol adheres to stringent quality management protocols. Every batch undergoes comprehensive analysis to ensure consistent isocyanate content (NCO%), viscosity, and hydrolyzable chloride levels meet strict specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed parameters.

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 material is moisture-sensitive (hygroscopic). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen or dry air) to prevent reaction with atmospheric moisture. Isolate from strong bases, acids, and oxidizing agents.
