Quality Control

Our production of this advanced polymer intermediate adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including determination of NCO content, viscosity, amine value, and catalyst concentration. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry atmosphere (e.g., under nitrogen) to prevent premature reaction and degradation. Keep away from heat, sparks, and open flame.
