Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical tests including viscosity, solids content, color, acid value, and functional group analysis. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each 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 temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
