摘要:
This invention relates to antisoiling compositions for antireflective substrates. More particularly, this invention relates to methods for depositing antisoiling compositions onto antireflective substrates. In particular, this invention relates to a method of depositing an antisoiling composition on an antireflective substrate comprising vaporizing an antisoiling composition and depositing the antisoiling composition onto an antireflective substrate. In another aspect, this invention relates to method of preparing an antireflective film stack comprising depositing an antireflective layer onto the surface of a transparent substrate and vapor depositing an antisoiling layer onto the surface of the antireflective layer. In yet another aspect, this invention relates to a method of depositing an antisoiling composition on an antireflective coated ophthalmic lens comprising vaporizing an antisoiling composition and depositing the antisoiling composition onto an antireflective coated ophthalmic lens.
摘要:
A composition comprising the condensation product of a least one fluorochemical polyether silane compound having a polyfluoropolyether segment and at least two hydrolysable silane groups per molecule, with one or more non-fluorinated compounds having at least two hydrolysable groups per molecule, and the reaction product thereof, is disclosed. The composition provides durable water, oil and stain repellency to a substrate.
摘要:
The invention provides a method of treating of a substrate by contacting the substrate with a fluorochemical composition that comprises a condensation product of a di- or tri-isocyanate and at least one polyether, the polyether being obtained as the reaction product of a fluorochemical substituted epoxide. Substrates treated in accordance with the invention have good stain release properties, particularly to oil stains or tea stains, so stains can be more easily removed from the treated substrate in a laundering procedure.
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.

An aqueous finishing agent for providing fibrous materials with a soft water and oil repellent treatment is provided. The finishing agent comprisesA) 25 to 65% by weight of a perfluoroaliphatic group-bearing water/oil-repellent agent (at least 5% by weight fluorine) in dispersion,B) 10 to 35% by weight of a dispersion of an emulsifiable polyethylene (density at 20.degree. C. at least 0.92 g/cm.sup.3, acid number at least 5) andC) 25 to 40% by weight of a fluorine-free dispersion of a soft-hand extender based on a modified hydrogen alkyl polysiloxane. A process for providing fibrous materials with a soft water and oil repellent treatment is also provided. The finishing agent provides fibrous material with excellent properties which are resistant to washing and dry cleaning and a particularly smooth, soft hand.
