Abstract:
A cost-effective process for treating a concrete structure includes the following steps. A surface of the concrete structure is coated with an organo-silicon compound and the organo-silicon coated surface is covered so as to reduce atmospheric exposure of the organo-silicon compound while the organo-silicon compound migrates into the concrete structure.
Abstract:
A treated hem flange is disclosed. The treated hem flange includes an outer panel and an inner panel including first and second opposing surfaces terminating at a cut edge. The inner panel is positioned within the outer panel. The treated hem flange also includes an electrocoat applied to the inner panel surfaces and the cut edge to form inner panel coated regions and inner panel exposed regions. The treated hem flange also includes a plasma polymer coat applied to the inner panel exposed regions to form a barrier coating.
Abstract:
A corrosion resistant substrate is provided having a Cr(VI) free corrosion resistant two layer coating. The substrate is substantially comprised of aluminum, an aluminum alloy, magnesium or a magnesium alloy. A first wet chemical deposited inorganic passivation layer is directly positioned on the substrate and a second organic modified polysiloxane layer is directly positioned on the passivation layer.
Abstract:
A method for coating metal surfaces, in particular surfaces of wheels made of an aluminium alloy, in a multi-step method, wherein the metallic surfaces are first contacted with an aqueous composition predominantly containing silane/silanol/siloxane/polysiloxane and thereafter contacted with an aqueous composition predominantly containing at least one phosphonic compound.
Abstract:
A method of imparting a non-stick coating to a surface of an aluminum foil sheet, and the resulting foil sheet. The method involves coating at least part (preferably at least 40%) of an area of a surface of a metal sheet article (preferably an aluminum foil sheet) with a substantially solvent-free silicone oil at an average coating application rate in a range of 1.5 to 10 mg/ft2 of the coated surface area. The coated sheet article is then preferably coiled. The coated sheet article is then heated in the presence of air or oxygen at a temperature of 250° C. or higher for a period of time of at least 10 minutes. The treated surface is both non-stick and food-friendly.
Abstract:
[Problems to be Solved] To provide a curable organopolysiloxane composition, wherein the composition can be laminated directly on the surface of an epoxy resin anticorrosive coating film and can form an antifouling coating film which has improved antifouling performance compared to the conventional art.[Means for Solving the Problems] A two-liquid type or three-liquid type curable organopolysiloxane composition, wherein the composition contains at least an organopolysiloxane having at least two condensation reactive groups in the molecule (a1), silica (a2), an organosilane and/or a partial hydrolyzate thereof (b1), wherein the organosilane has functional group(s) capable of undergoing condensation reaction with the condensation reactive groups of the above organopolysiloxane (a1), and at least one kind of tin compound selected from the group represented by a predefined general formula.
Abstract:
Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol (N) of polymer solution to a substrate (30) and substantially simultaneously applying an energy source (38) to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame (38) that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.
Abstract:
The present invention refers to coatings produced by means of the deposit of thin films formed by plasma-activated chemical vapor deposition of volatile fluoridated cyclic siloxanes having the structure [RR'SiO].sub.x, where R is an alkyl group with 1-6 carbon atoms, R' is a fluorinated alkyl group with 3-10 carbon atoms, the carbon in the alpha and beta positions with respect to the silicon atom is hydrogenated and x is 3 or 4. These particular coatings are useful because of their properties of protection and insulation.
Abstract:
The present invention relates to method for the production of a thermal fixing roller which comprises steps of applying a silicone rubber layer to the surface of a shaft, thereby forming a silicone rubber roller, applying a polytetrafluoroethylene coating to the surface of the silicone rubber roller by immersing the roller in a polytetrafluoroethylene dispersion and rotating the silicone rubber roller in a plane inclined with respect to a horizontal plane, removing the silicone rubber roller from the polytetrafluoroethylene resin dispersion, drying the coating on the outside of the silicone rubber roller at a temperature of at least 500.degree. C. for 10 to 120 seconds, preheating the coating from the inside of the silicone rubber roller, thereby elevating the temperature of the coating to a temperature which is less than that of the melting point of the polytetrafluoroethylene resin, and baking the coating to a temperature which is at least that of the melting point of the polytetrafluoroethylene resin.
Abstract:
This application relates to omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Methods of making such omniphobic surfaces with hierarchical structures and uses thereof, including as flexible films that repel contaminants are also disclosed in the application.
