Quality Control

Our Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Reaction Products With Chlorotrimethylsilane, Hydrochloric Acid, iso-Pr Alc. And Sodium Silicate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency, performance, and compliance with agreed specifications. Comprehensive Certificates of Analysis (COA) documenting key parameters such as viscosity, hydroxyl value, and silicon content are provided to guarantee product integrity for your industrial processes.

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/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent moisture absorption, which may affect product performance. Keep away from strong acids and bases.
