Quality Control

Our Ethylenediamine, Epichlorhydrin Polymer is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of key parameters such as charge density, viscosity, solids content, and residual monomers. Certificates of Analysis (COA) documenting compliance with agreed specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). Keep away from strong oxidizing agents, strong acids, and strong bases. The product is hygroscopic (moisture-sensitive); ensure containers are properly sealed after use to prevent moisture absorption and potential viscosity changes.
