Quality Control

Our production of this copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including solids content, viscosity, pH, and ionic character. A comprehensive Certificate of Analysis (COA) detailing these 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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption and potential lump formation.
