Quality Control

Our production of this anionic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solid content, viscosity, pH, and ionic character. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption and caking.
