Quality Control

Our Silicic Acid, Aluminum Potassium Sodium Salt is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Key parameters such as chemical composition, particle size distribution, and ion-exchange capacity are monitored. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at room temperature (15-25°C). The container must be kept tightly sealed after each use to prevent moisture absorption, which can affect flow properties and performance. Store away from strong acids and bases.
