Quality Control

Our Zinc Dichromate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and compliance with relevant industrial specifications. Each lot is analyzed for key parameters including purity, heavy metal content, and moisture. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee product integrity and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong reducing agents, organic substances, and combustible materials. Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term stability. Keep container tightly sealed when not in use to minimize exposure to atmospheric moisture.
