Quality Control

Our production of this specialty polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each 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 room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. This material is moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture.
