Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical applications. Quality is verified through parameters including solid content, viscosity, acid value, epoxy equivalent weight, and glass transition temperature (Tg). A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your formulation requirements.

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 strong acids and organic solvents. For long-term storage, consider using under an inert atmosphere to prevent oxidation or moisture uptake, which can affect polymer properties.
