Quality Control

Our Ammonium Zinc Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance for industrial applications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical specifications is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation from atmospheric moisture.
