Description

Triethoxy(3,3,3-trifluoropropyl)silane (CAS No. 86876-45-1) is a highly specialized organosilane compound with the molecular formula C₉H₁₉F₃O₃Si. This trifluoropropyl-functional silane is widely utilized as a coupling agent, surface modifier, and intermediate in advanced material synthesis. Its unique structure combines the reactivity of triethoxy silane with the hydrophobicity and chemical resistance imparted by the 3,3,3-trifluoropropyl group.

This high-purity reagent is particularly valuable for modifying inorganic surfaces (glass, metals, silica) to impart oleophobic and hydrophobic properties while maintaining excellent adhesion to substrates. The ethoxy groups enable facile hydrolysis and condensation reactions, making it ideal for sol-gel processes and hybrid material fabrication.

Packaged under inert atmosphere to ensure stability, our product undergoes rigorous QC testing including GC, NMR, and FTIR analysis to guarantee >98% purity. Available in quantities from 100mL to bulk drum sizes, with custom packaging options available for industrial users.

Application

This fluorinated silane is extensively used as a surface treatment for glass and ceramics to create oil- and water-repellent coatings. In polymer composites, it serves as a coupling agent between inorganic fillers and fluoropolymer matrices. The compound also finds application in the preparation of low-surface-energy coatings for optical and electronic devices. Researchers employ it to create superhydrophobic surfaces and as a precursor for functionalized silica materials.
