Quality Control

Our Polymethyl-3,3,3-Trifluoropropylsiloxane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including verification of viscosity, fluorine content, and chemical purity. Certificates of Analysis (COA) documenting key specifications 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, well-ventilated area at room temperature (typically 15-25°C). Keep away from strong acids and incompatible materials. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
