Abstract

This invention is concerned with a process for bonding a durable low surface energy polymeric coating to a metal or oxide surface. The metal or oxide surface is first treated with an alkali, thereby maximizing the hydroxide ion concentration on the surface, and then in a rigorously dry state with a rigorously dry fluorinated material to form the polymeric coating. The fluorinated material has the formula EQU Rf -- O -- (CH.sub.2).sub.n -- SiX.sub.3 wherein Rf is a fluorinated lower alkyl group, n is an integer from 2 to 10, and X is a halogen, cyanide or alkoxy group.
