The present invention provides liquid, destructible fluorinated nonionic surfactants that are water-soluble or dispersible, that are useful as stabilizers for emulsions, and that on curing as a layer on a substrate can provide the substrate with an oil- and water-repellent coating that is free of surfactant, the destructible surfactant comprising a fluorocarbylalkoxysilane having at least one polyfluorinated aliphatic group that is both hydrophobic and oleophobic and at least one, preferably two, polyoxyalkylene or other hydrophilic groups which can be cleaved from the hydrophobe by hydrolysis. More particularly, a fluorocarbylalkoxysilane comprises at least one polyfluorinated aliphatic group and at least one polyoxyalkylene group or other hydrophilic group, said fluorocarbylalkoxysilane being destructible by hydrolysis.

The invention further provides an aqueous composition for providing a substrate with an oil and water repellent coating comprising the fluorocarbylalkoxysilane of the invention as well as a process for providing a substrate with an oil and water repellent coating.
