Quality Control

Our 1H,1H,2H,2H-Perfluorodecyltriethoxysilane is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and GC, to ensure high purity and consistent performance. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all relevant specifications. Our quality system is designed to meet the stringent requirements of industrial and R&D applications, ensuring supply reliability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for long-term stability.
