Quality Control

Our Aluminium Sodium Orthosilicate Hydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets defined specifications for parameters such as assay, moisture content, and particle size distribution. 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 nature, the material must be stored in a cool, dry place with minimal humidity exposure. The recommended storage temperature is 15-25°C. Ensure the container is kept sealed after each use to prevent moisture absorption and caking.
