A water- and oil-repellent, antistatic composition comprises (a) at least one nonpolymeric ionic salt consisting of (i) at least one cation selected from the group consisting of monovalent metal cations, divalent metal cations, and organic onium cations, and (ii) at least one weakly coordinating anion, the conjugate acid of the anion having an acidity greater than or equal to that of a hydrocarbon sulfonic acid, and with the proviso that the anion is organic or fluoroorganic when the cation is a metal; (b) at least one fluorochemical repellency-imparting additive or repellent; and (c) at least one insulating material. The composition exhibits good antistatic and repellency characteristics.
Cette composition antistatique hydrofuge et oléofuge réunit (a) au moins un sel ionique non polymère, (b) au moins un répulsif, et (c) au moins un matériau isolant. Le sel ionique non polymère (a) est constitué d'un cation (i) et d'un anion faiblement coordinateur (ii). Le cation (i) appartient au groupe des cations de métaux monovalents, des cations de métaux divalents et des cations onium organiques. L'acidité de l'acide de conjugaison de l'anion (ii) est au moins égale à celle d'un acide sulfonique d'hydrocarbure, l'anion étant organique ou organofluoré lorsque le cation est un métal. Le répulsif (b) est un additif à base de composé fluoré conférant une résistance au mouillage. Cette composition se distingue par ses très bonnes qualités d'antistaticité et de résistance au mouillage.
