1H,1H,2H,2H-Perfluorooctyltriethoxysilane

Fluorinated alkyl silane. Long perfluoroalkyl chain — gives the lowest surface energy of the family and true oleophobicity. Eight-carbon (C8) perfluoroalkyl chain on a triethoxysilane anchor — shorter chain than the C10 grade, releasing ethanol rather than methanol on hydrolysis.
