It has been shown that for obtaining hydrophobic coatings, it is reasonable to use fluoroalkylalkoxysilanes (FASs) with a longer fluoroalkyl chain than FAS-19, so that the F/Si molar ratio exceeds 5–6. It is proposed to purposefully change not only the chain length of oligomers, but also the structure of solutions from dilute colloidal solutions to structured gels, with the F/Si ratio being controlled. In the case of polycondensation of investigated fluoroalkylalkoxysilanes on a hydroxylated surface, a strong silicone framework is formed, which is chemically bonded to the surface and to fluoroalkyl chains oriented perpendicular to it
