Quality Control

Our production of 2-Propenoic Acid, Polymer With Ethenylbenzene, Ammonium Zinc Salt adheres to stringent quality management protocols. Each batch undergoes rigorous testing for critical parameters including ionic content, polymer composition, viscosity, and residual monomers to ensure batch-to-batch consistency and performance reliability. 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
