Abstract

A composition and method are disclosed whereby a subsrate such as glass, plastic, metal, inorganic polymer coated substrate or inorganic coated substrate is provided with a durable non-wetting surface by treatment with a perfluroalkylalkyl silane in a solvent which together form a composition which initially wets the furface. Said perfluoroalkylalkyl silane is selected from compounds having the general formula RmR'nSiX4-m-n, wherein R is a perfluoroalkylalkyl radical, R' is an alkyl or vinyl radical, m + n is not greater than 3, and X is selected from the group consisting of halogen, alkoxy and acyl radicals. As the perfluoroalkylalkyl silane reacts with the surface, the remaining composition is repelled by the perfluoroalkylalkyl silane treated surface due to the difference between the surface tension of the solvent and the free energy of the treated surface, for expedient removal of the remaining composition from the treated surface.
