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.

Abstract: A method for producing a low-molecular fluorine compound, including a decomposition step for heating a microwave absorber by the irradiation with microwaves in a reaction vessel provided with a carrier gas inlet and a decomposed gas outlet and then bringing the heated microwave absorber into contact with particles of a material containing a fluororesin to decompose the fluororesin into the low-molecular fluorine compound, wherein the carrier gas temperature TI (° C.) at the inlet is set to a temperature lower than the temperature TR (° C.) of the heated microwave absorber. Accordingly, a temperature difference can be provided such that the temperature of a produced gas discharged from the reaction vessel becomes lower than the temperature in the decomposition reaction system, i.e., the temperature of the heated microwave absorber.
