A surface treating composition is shown and described herein. A surface treating composition comprises (i) a hybrid siloxane oligomer comprises organosilicon units wherein the oligomer comprises organosilicon units with fluoro-functional groups, and organosilicon units with other reactive functionality, and (ii) a perfluoro(poly)ether group containing silane compound. The surface treating composition can be employed to provide a hydrophobic and/or oleophobic surface coating on a surface of a substrate, which may impart other beneficial properties to the article. La présente invention concerne une composition de traitement de surface. La composition de traitement de surface comprend (i) un oligomère de siloxane hybride comprenant des unités d'organosilicium, l'oligomère comprenant des unités d'organosilicium comportant des groupes fonctionnels fluorés et des unités d'organosilicium comportant d'autres fonctions réactives, et (ii) un composé silane contenant des groupes perfluoro(poly)éther. La composition de traitement de surface peut être utilisée pour fournir un revêtement de surface hydrophobe et/ou oléophobe sur une surface d'un substrat, qui peut conférer d'autres propriétés avantageuses à l'article.
