Quality Control

Our Zinc Metasilicate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Quality parameters including chemical purity, particle size distribution, and specific surface area are rigorously tested. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance protocols.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
