Abstract: A lubricating grease containing about 75 to 85% by weight of a liquid perfluoropolyether and about 15 to 25% by weight of a particulate boron nitride, preferably monomodal boron nitride having a particle size of about 7 to 10 microns; use of the lubricating grease for lubricating structures subjected to an oxygen-enriched environment and devices containing such lubricated structures.

Abstract: A composition useful for imparting durable stain repellence and soil release properties to textile substrates, a method for treating textile substrates using such composition, and the textile substrates obtained therefrom. The composition comprises: (A) at least one fluorinated ionisable polyurethane polymer (PUR) being free from perfluoroalkyl chains and comprising at least one fluorinated block comprising a fluoropolyoxyalkene chain, and at least one functional block comprising an hydrocarbon chain (RHC) having from 2 to 14 carbon atoms, said chain (RHC) comprising at least one ionisable group, said blocks being linked by urethane moieties of formula (I), wherein E is a divalent hydrocarbon carbon group; (B) at least one fluorocarbon polymer (F) comprising at least one perfluoroalkyl chain (Rf) linked by one or more ester moiety of formula (II) and/or urethane moiety of formula (III) and/or urea moiety of formula (IV); and (C) at least one crosslinking agent.

Abstract: The present invention relates to additives for lubricating oils and greases which endow said lubricating oils and greases extremely good performance characteristics under boundary lubrication conditions. Such additives are derivatives of monofunctional or difunctional perfluoropolyethers constituted by mercaptans, sulfides, disulfides, phosphines, phosphine-oxides and phosphoric acid triesters.
