Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, solids content, hydroxyl value, and color are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are available for every batch upon request, supporting your quality assurance and regulatory compliance needs.

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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect product performance.
