Quality Control

Every batch of our anionic copolymer is manufactured under a strict quality management system. We ensure compliance with relevant industry standards through rigorous in-process and final product testing. A comprehensive Certificate of Analysis (COA) detailing assay, viscosity, pH, solid content, and other critical parameters is provided with each shipment to guarantee batch-to-batch consistency and performance.

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); the container must be kept tightly sealed after initial use to prevent moisture absorption and caking.
