Quality Control

Our Zinc Phosphate Hydrate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. The product undergoes rigorous testing for parameters including chemical identification, assay (zinc and phosphate content), moisture (loss on drying), and impurity profiles. Certificates of Analysis (COA) documenting compliance with agreed specifications are available for every batch shipped.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
