Abstract
The present invention relates to an article comprising a polymeric substrate and a coating thereon comprising a complex of an ionic fluoropolyether and a counter-ionic agent, to a process for the production of a coating on a polymeric substrate comprising the steps of a) preparing a mixture of an ionic fluoropolyether or a precursor thereof and a counter-ionic agent of a precursor thereof and b) applying the mixture prepared in step a) onto the substrate, to the use of such articles for the manufacture of a garment, a filter element, a venting element or a protective enclosure, to the use of a coating composition comprising a complex of an ionic fluoropolyether and a counter-ionic agent for coating of a polymeric substrate, and to the use of a coating composition comprising a complex of an ionic fluoropolyether and a counter-ionic agent as an antimicrobial or antifungal coating of a substrate.
