Abstract:
A coating of an encapsulated electrophoretic medium is formed on a substrate (106) by dispersing in a fluid (104) a plurality of electrophoretic capsules (102), contacting at least a portion of a substrate (106) with the fluid (104); and applying a potential difference between at least a part of the portion of the substrate (106) contacting the fluid (104) and a counter-electrode (110) in electrical contact with the fluid (104), thereby causing capsules (102) to be deposited upon at least part of the portion of the substrate (106) contacting the fluid (102). Patterned coatings of capsules containing different colors may be deposited in registration with electrodes using multiple capsule deposition steps. Alternatively, patterned coatings of capsules may be formed by applying a fluid form of an electrophoretic medium to a substrate, and applying a temporally varying voltage between an electrode and the substrate. The process may be repeated to allow for deposition of full color displays.
Abstract:
The invention provides methods for producing flexible, stretchable, and/or elastic products comprised principally of material such as natural elastomers and other synthetic polymers. The method for producing stretchable products by spraying product material over a workpiece former, and method for creating perforated products by spraying product material over fibres in an upright position. The invention provides methods for making double sided fibre coating of the product and, or to at least coating the product surface on the side facing the wall without the need for removing the product from the wall.
Abstract:
A flexible metallic strip product including a ferritic chromium strip steel material having a coating of an electrically insulating layer of zirconia stabilized with yttrium, said coating being intended to receive a second coating of an electrically conducting layers is disclosed. This coating is very efficient as an electrically insulating layer in flexible solar cells and solid state thin film batteries because it has practically the same thermal expansion coefficient as the steel substrate.
Abstract:
The disclosed method relates to manufacture of a near net-shaped products such as ceramic containing products such as ceramic-metal composites. The method entails forming a mixture of a build material and a binder and depositing that mixture onto a surface to produce a layer of the mixture. An activator fluid then is applied to at least one selected region of the layer to bond the binder to the build material to yield a shaped pattern. These steps may be repeated to produce a porous whitebody that is heat treated to yield a porous greenbody preform having a porosity of about 30% to about 70%. The greenbody then is impregnated with a molten material such as molten metal. Where the build material is SiC, the molten metal employed is Si to generate a SiC—Si composite.
Abstract:
A method of fabricating electro-phoretic display is performed by the steps of: providing a first electrode substrate and a second electrode substrate disposed above the first electrode substrate in an electro-phoretic liquid, wherein the first electrode substrate comprises a substrate and a plurality of pixel electrodes disposed on the substrate; putting at least a charged micro-capsule between the first electrode substrate and the second electrode substrate in the electro-phoretic liquid; making the electricity of a portion of the pixel electrodes is opposite to the electricity of the charged micro-capsules for attracting the charged micro-capsules to above the portion of the pixel electrodes. Since the charged microcapsules are disposed on the pixel electrodes immediately and the micro-capsules corresponded to the same pixel electrode have a plurality of colorful charged particles with the same color, the electric-phoretic display fabricated by this method may not only have high reflectivity and transmittance, but also display a picture with single original color.
Abstract:
A formulation for a high performance Photoluminescent powder coat and a process by which a substrate is covered with multiple layers to give both photoluminescent and other advantageous qualities to said substrate. The first layer applied to the substrate is a retroreflective layer to provide retroreflective action to the second photoluminescent layer. A variety of translucent layers can then be applied over the photoluminescent layer to give such properties as antibacterial or antimicrobial action, non-slip surface or durability, and special textures. The layers can also provide such advantageous qualities as temperature resistance and electroconductivity or electrodissipation. Although this process has a variety of applications, it gives specific advantage to all forms of door hardware, both providing illumination for low-light conditions and advanced qualities such as heat or flame resistance.
Abstract:
The present invention relates to an aluminum wheel having high gloss and a method for manufacturing the same, and the method for manufacturing an aluminum wheel having high gloss includes the steps of: (i) coating a primary coating powder paints for increasing a flatness of an aluminum wheel having a rough surface and improving an adhesive force to a silver mirror coating surface, (ii) forming of silver coating layer forming a mirror surface having a high gloss and high reflectivity on the powder paints coated surface using a silver coating solution, and (iii) forming at least one transparent top coating for protecting the silver mirror surface and increasing an abrasion resistance and a saltwater resistance after the step (ii). In accordance with the present invention, an aluminum wheel having high gloss and high reflectivity can be manufactured in a simple processes and relative inexpensive cost.
Abstract:
A process for forming a release surface on a substrate includes applying a primer powder on the substrate to form a primer layer, applying an overcoat powder on the primer layer to form an overcoat layer, and baking the substrate after applying both the primer powder and the overcoat powder. The primer powder includes a tetrafluoroethylene/perfluoroolefin copolymer and a non-melt processible binder. The overcoat powder includes a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer.
Abstract:
A component subjected to wear during use includes a powder coating formed of a polymer selected from the group consisting of a polyamide, polyolefin, polyester, urethane, epoxy, acrylic, and mixtures thereof to provide improved wear resistance, enhanced cleanability, and reduced surface friction. Preferably, the component is for use in conveying product, such as in a conveyor system, and includes: (1) a metal core and a nylon powder coating; or (2) a stainless steel core and a powder coating. Most preferably, the coating is generally clear or translucent so as to give the appearance that the underlying component, which is typically made of metal, is neither coated nor made entirely of a polymer.
