Abstract: 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.
