摘要:
Described are compositions containing fluorinated polyether isocyanate derived silane compounds for treating substrates such as hard surfaces, e.g. ceramic and/or glass, to render them oil and water repellent, and stain resistant, articles having coatings comprising such compounds, and methods for applying such coatings.
摘要:
Foamable compositions comprise (a) at least one normally liquid, unsaturated perfluorochemical blowing agent compound selected from the group consisting of perfluoroolefin compounds, e.g., perfluoro(4-methylpent-2-ene), perfluoroaromatic compounds, e.g., hexafluorobenzene, and perfluorocycloolefin compounds, e.g., perfluorocyclohexene, the perfluoroolefin compounds optionally containing one or more catenary heteroatoms; and (b) at least one foamable polymer or the precursors of at least one foamable polymer. The compositions are useful in preparing polymeric, e.g., polyurethane, foams.

A method of treating a hydrocarbon-bearing formation with a fluorinated epoxide and a treated hydrocarbon-bearing formation. A method of making proppants is also disclosed, which includes combining a plurality of particles with a fluorinated epoxide. The particles comprise at least one of sand, resin-coated sand, ceramic, thermoplastic, clay, bauxite, nut or seed shells, fruit pits, or wood. A particle treated with a ring-opened product of a fluorinated epoxide is also disclosed, wherein the particle comprises one of sand, resin-coated sand, ceramic, thermoplastic, clay, bauxite, nut or seed shells, fruit pits, or wood.
摘要:
A method of forming an easy-to-clean metal or metallized substrate, the method comprising forming a layer comprising silicon, oxygen, and hydrogen on at least a portion of a surface of the substrate by plasma deposition; and applying an at least partially fluorinated composition comprising at least one silane group to at least a portion of a surface of the layer comprising the silicon, oxygen, and hydrogen; and an easy-to-clean article made by the method are disclosed.
摘要:
The invention relates to a dilutable, non-aqueous concentrate and an aqueous dilution used for aqueous delivery of fluorinated oligomeric silanes to a substrate, a method of treating a substrate with the aqueous dilution composition to render it oil and water repellent, and articles having coatings made from the aqueous dilution.
摘要:
A polymeric or oligomeric composition comprising at least one first divalent unit represented by formula: and at least one of a second divalent unit comprising a pendant phosphonate group —P(O)(OY)2 or a monovalent unit comprising a thioether linkage and a terminal Z group, wherein each Z group is independently —P(O)(OY)2 or —O—P(O)(OY)2. Rf is a perfluoropolyether group. Q is a bond, —C(O)—N(R1)—, or —C(O)—O—. R″, R′″, R and R1 are each independently hydrogen and alkyl having from 1 to 4 carbon atoms. X is alkylene, arylalkylene, and alkylarylene, wherein alkylene, arylalkylene, and alkylarylene are each optionally interrupted by at least one ether linkage. Y is hydrogen, alkyl, trialkylsilyl, and a counter cation. Methods of treating a surface using these compositions and articles with a surface in contact with these compositions are provided. Methods of making these compositions are also provided.
