Patent number: 7838475Abstract: A composition is disclosed which comprises an aryl perfluoropolyether, optionally a halogenated oil, and further optionally a thickening agent. The composition can be used as a lubricant itself or as an additive to an oil or grease lubricant and can withstand temperatures higher than 300° C. without decomposition. The halogenated oil can be a perfluoropolyether, a fluorosilicone, a polytrifluorochloroethylene, or combinations of two or more thereof. The thickening agent can be finely divided silica, boron nitride, clay, soap, poly(tetrafluoroethylene), clay, talc, silica, titanium dioxide, polydimethylsiloxane, polyurea, polyurethane, or combinations of two or more thereof.Type: GrantFiled: September 1, 2005Date of Patent: November 23, 2010Assignee: E.I. du Pont de Nemours and CompanyInventors: Jon Lee Howell, Alice Elizabeth Van Der Ende, Erik William Perez, Krista Lynn Laugesen

Publication number: 20100240557Abstract: A perfluoropolyether oil composition, which comprises a perfluoro-polyether base oil, preferably a thickener-containing perfluoropolyether base oil, and a fluorine-containing di- or mono-amide-based compound having a perfluoropolyether group, where 0.01 to 50% by weight of the amide-based compound, based on total weight of the base oil and the amide-based compound, is contained when the perfluoropolyether oil composition is used as a lubricating oil composition, particularly grease, and 0.01 to 90% by weight thereof is contained, when the perfluoropolyether oil composition is used as an electrode-coating agent for a cell. The perfluoropolyether oil composition shows a metal surface protective action against corrosive gases such as sulfide gases, etc. without deteriorating the abrasion resistance, and also shows a distinguished high temperature durability even in the presence of graphite or molybdenum disulfide.Type: ApplicationFiled: March 25, 2010Publication date: September 23, 2010Applicant: NOK KLUBER CO., LTD.Inventors: Yuji WATANABE, Yasumichi KIDO, You DOI, Miyuki HASHIDA, Toshio NITTA, Tatsuya HASHIMOTO, Akira OTANI, Jiro YURIMOTO
