<p>A composition for producing a water repellent surface on a substrate such as glass, plastic, metal, organic polymer coated substrates or inorganic coated substrates includes a perfluoroalkylalkylsilane selected from compounds having the general formula RmR'nSiX4-m-n where R is a perfluoroalkylalkyl radical, R' is a vinyl or an alkyl radical, m+n is less than 4, and X is a halogen, alkoxy or an acyloxy radical and a completely hydrolyzable silane or siloxane selected from silanes and siloxanes. The nonwetting property, as measured by contact angle of a drop of water on the substrate surface treated with the foregoing compound, is more durable than the nonwetting property of a surface treated with the same perfluoroalkylalkylsilane without the completely hydrolyzable silane or siloxane.</p> |
