Quality Control

Our Bis(Trifluoropropyl)Tetramethyldisiloxane is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all critical specifications. Our quality commitment ensures the material meets the exacting standards required for advanced industrial and R&D applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and potential concentration changes. Recommended storage temperature is 2-25°C.
