Quality Control

Our Aluminium Phosphate Hydrate is produced under strict quality management protocols to ensure batch-to-batch consistency and compliance with relevant industrial standards. Each lot is subjected to rigorous analytical testing, including assay, impurity profiling, and physical characterization. A comprehensive Certificate of Analysis (COA) detailing purity, loss on drying, and other critical parameters is provided with every shipment to guarantee product integrity for your applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the material must be stored in a cool, dry place at a controlled room temperature (15-25°C) with low humidity. For long-term storage, consider using desiccants or a dry inert atmosphere to prevent moisture uptake and caking.
