CA 2503997

A conduit such as a nozzle having its surface or a portion of its surface coated with a thin fluid-repellent layer is disclosed. The layer comprises or is produced from a fluorocarbon silane or a substantially aqueous emulsion. The emulsion comprises or is produced from (1) a fluorocarbon silane or its hydrolyzate, (2) water, and (3) optionally a surfactant, a silicon compound, a catalyst, or combinations of two or more thereof where the fluorocarbon silane has the formula Rf-(CH2)p-Si{-(O-CH2CH2)n-OR1}3 and the silicon compound can be a silicate or an organoalkoxysilane; Rf is a C3-18 perfluoroalkyl group or combinations of two or more thereof; each R1 is independently one or more C1-3 alkyl groups; p is 2 to 4; and n is 2 to 10.

L'invention concerne un conduit, tel qu'une buse dont la surface ou une partie de celle-ci est enduite d'une fine couche imperméable. Ladite couche comprend un silane fluorocarboné ou une émulsion sensiblement aqueuse ou est fabriquée à partir de ceux-ci. Ladite émulsion comprend ou est fabriquée à partir de : (1) un silane fluorocarboné ou son hydrolysat, (2) de l'eau, et (3) éventuellement un tensioactif, un composé de silicium, un catalyseur, ou des combinaisons d'au moins deux d'entre eux, le silane fluorocarboné étant représenté par la formule R¿f?-(CH¿2?)¿p?-Si{-(O-CH¿2?CH¿2?)¿n?-OR?1¿} et le composé de silicium peut être un silicate ou un organoalcoxysilane ; R¿f? représente un groupe perfluoroalkyle C¿3?-¿18? ou des combinaisons d'au moins deux d'entre eux ; Chaque R?1¿ représente indépendamment un ou plusieurs groupes alkyle C¿1-3? ; p vaut 2 à 4 et n vaut 2 à 10.? ¿
