Quality Control

Our Kieselsure, Natriumsalz is manufactured under a strict quality management system. Production batches are analyzed against key parameters such as SiO2/Na2O ratio, density, viscosity, and solids content to ensure consistent performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing the specific grade's specifications. Our quality commitment supports compliance with relevant industrial standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. For long-term storage, ensure containers are sealed to prevent absorption of atmospheric moisture (carbon dioxide), which can lead to precipitation.
