Abstract:
A process, capable of commercial scale manufacturing of inexpensive, integral film product without the waste of die-cutting and which products are capable of use independent of a supporting structure on which they are formed, includes placing a mask over a substrate having a releasable surface, delivering a film-forming composition through the mask to form a raw shape on the substrate; removing the mask, and solidifying the raw shape into the integral film product disposed on the substrate. The mask has at least one aperture having a shape corresponding to the desired integral film product. The integral film product is arranged and configured to be removable from the releasable surface of the substrate for use independent of the substrate.
Abstract:
A method for applying a protective coating to selected portions of a substrate is disclosed. The method includes applying a mask to or forming a mask on at least one portion of the substrate that is not to be covered with the protective coating. The mask may be selectively formed by applying a flowable material to the substrate. Alternatively, the mask may be formed from a preformed film. With the mask in place, the protective coating may be applied to the substrate and the mask. A portion of the protective coating that overlies the mask may be delineated from other portions of the protective coating; for example, by cutting, weakening or removing material from the protective coating at locations at or adjacent to the perimeter of the mask. The portion of the protective coating that overlies the mask, and the mask, may then be removed from the substrate.
Abstract:
A liquid ejection head has recessed portions are formed in an ejection face, such that a distance d1 is between a center of an ejection opening in one recessed portion and an other-side side face of another recessed portion adjacent thereto on one side, where a distance d2 is between the center and a one-side face of another recessed portion adjacent to the one recessed portion on the other side, and where a distance x1 is between the center and a one-side side face of the one recessed portion, and a distance x2 is between the center and an other-side side face thereof. A central position of a bottom portion of the one recessed portion is positioned relative to the center, such that a relationship between distance d1 and distance d2 is the same as a relationship between distance x1 and distance x2.
Abstract:
A method for forming an electronic device having a multilayer structure, comprising: embossing a surface of a substrate so as to depress first and second regions of the substrate relative to at least a third region of the substrate; depositing conductive or semiconductive material from solution onto the first and second regions of the substrate so as to form a first electrode on the first region and a second electrode on the second region, wherein the electrodes are electrically insulated from each other by the third region.

Still further, a curable resin composition for surface protection, comprising (A) a polyfunctional (meth)acrylate, (B) a monofunctional (meth)acrylate, (C) a resin having a cyclopentadiene skeleton, (D) a photopolymerization initiator, and (E) a polar organic solvent.
Abstract:
A method for producing a substrate including a layer includes providing that the layer is a full or a partial surface macro-structured layer, applying a sol-gel solution in already structured form onto the substrate, and drying and/or baking, resulting in a sol-gel layer.
Abstract:
A system and method that can be used to cover a portion (e.g., a clear aperture) of an optical element (e.g., a lens) during coating of another portion (e.g., a circumferential portion) of the optical element. This can be done to protect the clear aperture during coating of an adhesive protection layer proximate a circumferential edge of the lens without damaging or altering the clear aperture. The method can include the following steps. An optical element is held so that a first portion of the optical element is covered and a second portion of the optical element is exposed. A first coating is provided on the second portion of the optical element. The optical element is released from being held. A second coating is provided on the optical element. The first and second coatings are removed from the second portion of the optical element.
Abstract:
Systems and methods are disclosed by which patterns of various materials can be formed on flexible substrates by a continuous roll-to-roll manufacturing process. The patterns may include metallic, transparent conductive, or non-metallic elements with lateral dimensions including in the range from below 100 nanometers to millimeters and with thickness dimensions including the range from tens of Angstroms to greater than 10,000 Angstroms. The substrate may be any material capable of sufficient flexibility for compatibility with roll-based processing equipment, including polymeric films, metallic foils, and thin glass, with polymeric films representing a particularly broad field of application. Methods may include the continuous roll-to-roll formation of a temporary polymeric structure with selected areas open to the underlying substrate, the continuous addition or subtraction of constituent materials, and the continuous removal, where necessary, of the polymeric structure and any excess material.
Abstract:
The present invention relates to an improved sealing composition and method. The sealing composition uses near equal amounts by weight or volume of a pre-polymer and curative. The mixture is applied by a portable spray apparatus using a mixing spray nozzle. For temporary sealing coatings using the present invention a releasing agent is applied to the surface to be sealed. The present invention is ideally suited to protect bath tubs, whirlpools, shower stalls, shower pans, tile, marble, glass, metal, hardwoods, other smooth, non-porous surfaces, and the like. The resulting protective coat from the present invention is impenetrable to ladders, boots, sheet rock, mud, paint, dirt, metal pieces, rocks, gravel, sand, grime which might accompany work on or around the surface to be sealed and thus protected. The present invention also provides a means to avoid scratching, nicking, marring, chipping, staining, painting, and abrading from these and a multitude of other external forces or objects. As a permanent coating, the present invention can guard against weather, water, sun damage, wind damage, or provide attributes specifically needed on certain surfaces such as improved traction for wet or water-exposed surfaces.
Abstract:
A protective material comprising a pre-polymer and a curative is applied to a finished surface. Near equal amounts of the pre-polymer and curative are mixed, pre-heated, and applied to the finished surface by a portable spray mixer apparatus having a disposable mixing spray nozzle. For temporary protection, a releasing agent is applied to the finished surface prior to application of the protective material. The short cure period of the present invention facilitates repeated, fast applications in construction sites to provide impenetrable protection for finished surfaces.
