ABSTRACT:
A method for reducing the chemical vapor permeability of a polyfluoroorgano resin substrate by coating its surface with a vinylidene dichloride copolymer is disclosed. The method produces a polyfluoroorgano resin substrate-vinylidene dichloride copolymer composite, for example a Teflon PFA pipe having its surface immediate to the environment treated with a vinylidene dichloride/vinyl chloride copolymer.
