Quality Control

Our Calcium Borate Silicate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. The product undergoes comprehensive analytical testing, including assessment of chemical composition, particle size distribution, and moisture content. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect flow properties and performance. Keep away from incompatible materials.
