Abstract | Aqueous coating compositions are provided comprising fluoropolymers that exhibit excellent stain release and stain resistance properties. In one embodiment, the compositions comprise little or no surfactant. In another embodiment, the compositions comprise a blend of a film-forming polymer comprising at least one pendent fluoro-containing functionality; and a non-film-forming polymer comprising at least one pendent highly fluorinated functionality. In another embodiment, the compositions comprise a blend of about 20 to about 98 percent by weight of a polymer comprising at least one pendent fluoroalkoxyalkyl functionality and about 2 to about 80 percent by weight of an oleophobic polymer. Coated articles and methods are also provided.
L'invention concerne des compositions aqueuses de revêtement qui comprennent des polymères fluorés présentant d'excellentes propriétés antitaches et de résistance aux taches. Dans une forme de réalisation, les compositions comprennent peu ou pas de tensioactif. Dans une autre forme de réalisation, les compositions renferment un mélange de polymère filmogène qui comprennent au moins une fonctionnalité disponible contenant un fluoro ; et un polymère non filmogène comprenant au moins une fonctionnalité disponible à forte teneur en fluor. Dans une autre forme de réalisation encore, les compositions comprennent un mélange d'environ 20 à environ 98 pour cent en poids d'un polymère comprenant au moins une fonctionnalité fluoroalcoxyalkyle disponible et d'environ 2 à environ 80 pour cent en poids d'un polymère oléophobe. Des articles revêtus et des procédés sont également décrits. |
