Quality Control

Our Potassium Silicate is manufactured under a stringent quality management system. Key parameters such as the SiO2/K2O ratio, solids content, viscosity, and density are rigorously controlled to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent caking or reaction with atmospheric moisture and carbon dioxide.
