Quality Control

Our production of this advanced polymer intermediate adheres to strict quality management systems, ensuring batch-to-batch consistency and reliability. Key parameters such as epoxy equivalent weight (EEW), isocyanate content, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing purity and performance specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at a recommended temperature of 15-25°C (59-77°F). Due to its hygroscopic and light-sensitive nature, containers must be kept sealed under a dry atmosphere (e.g., nitrogen blanket) after opening to prevent moisture absorption and premature polymerization. Keep away from heat, sparks, and open flame.
