Quality Control

Our production of this polymeric additive follows rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. While it is typically supplied as a technical grade material, specifications are tightly controlled for key parameters such as active content, viscosity, pH, and ionic character. A Certificate of Analysis (COA) detailing these parameters is provided with every shipment to support your quality assurance processes.

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 alkalis and incompatible materials. The product has good shelf stability under these conditions; prolonged exposure to elevated temperatures or moisture should be avoided.
