A method for coating large-area glass substrates, the method having the following steps: a) applying a water-soluble layer to at least one first predetermined region of the surface of a glass substrate, wherein at least one second predetermined region of the surface of the glass substrate remains free of the water-soluble layer; b) coating the surface of the glass substrate with at least one non-water-soluble layer; c) removing the water-soluble layer, wherein steps a)-c) are carried out multiple times in succession.

This disclosure features use of a paper or polymer film that includes a slip agent that can transfer to its surfaces. Once the paper or film is pressed against a glass sheet, this will leave a thin surface roughness of slip agent that can prevent or reduce glass surface scratches from other surfaces or particles during shipping or finishing (e.g., cutting to size, conveyance of glass), thereby improving the yield of glass shipments between glass forming plants and customers. The thin discontinuous layer of slip agent remaining on the glass surface can be washed off easily in subsequent washing processes. The paper or film can have the slip agent imbibed within the paper or coated on it as a surface member.

A method of making a strengthened glass article includes providing a flat glass article having a select contour and a glass surface covered by a protective coating layer. The protective coating layer is removed from the glass surface without touching the glass surface with any solid object. Immediately after the protective coating layer is removed from the glass surface, the flat glass article is subjected to an ion-exchange process to strengthen the flat glass article and improve the resistance of the flat glass article to subsequent damage.

A method of making a heat treated (HT) or heat treatable coated article. A method of making a coated article includes a step of heat treating a glass substrate coated with at least layer of or including carbon (e.g., diamond-like carbon (DLC)) and an overlying protective film thereon. In certain example embodiments, the protective film may be of or include both (a) an oxygen blocking or barrier layer, and (b) a release layer of or including zinc oxide. Treating the zinc oxide inclusive release layer with plasma including oxygen (e.g., via ion beam treatment) improves thermal stability and/or quality of the product. Following and/or during heat treatment (e.g., thermal tempering, or the like) the protective film may be entirely or partially removed.

A method includes heating a glass preform having a plurality of glass layers and drawing the glass preform in a distal direction to form a drawn glass sheet extending distally from the glass preform and having the plurality of glass layers. The drawn glass sheet is thinner than the glass preform. The drawn glass sheet can be rolled onto a collection spool. At least a portion of a glass layer can be removed from the drawn glass sheet. An exemplary glass sheet includes a first glass layer, a second glass layer adjacent to the first glass layer, and a thickness of at most about 0.1 mm. An exemplary ion exchanged glass sheet includes a thickness of at most about 0.1 mm and a surface layer that is under a compressive stress and extends into an interior of the glass sheet to a depth of layer.

A protected substrate includes a planar substrate having a surface and a burn-off temporary protective layer positioned over at least a portion of the surface. The burn-off temporary protective layer includes a wax, a polyolefin, a polyester, a polycarbonate, a polyether, or some combination thereof. The burn-off temporary protective layer is removable by a heat treatment process that does not substantially damage the surface. Various other protected substrates and methods for protecting a substrate are also disclosed.

Provided is a Low-E glass plate protection method capable of preventing or inhibiting Low-E layer alteration. In the protection method, a protective sheet having a substrate and a PSA layer provided to at least one face of the substrate is applied for protection via the PSA layer to a Low-E glass plate having a Low-E layer that comprises a zinc component. The method is characterized by using the protective sheet wherein the PSA layer is formed from a water-dispersed PSA composition and includes less than 850 g ammonia per gram of PSA layer weight.

Methods for marking glass sheets, preferably single-pane safety glass sheets.

The disclosure belongs to a field of a micro-nano processing technology, and more specifically, relates to a method and application of isotropic shrinkage of a three-dimensional micro-nanostructure. In the disclosure, the high polymer film is prepared by mixing the high polymer material and the solvent, and then spin-coating it on a surface of a substrate. Then, the high polymer film is etched to expose a portion of the surface of the substrate, and a raw material of a three-dimensional structure is processed into a target three-dimensional structure with an etched area as an initial processing position. Then, the target three-dimensional structure is subjected to a stiffness strengthening treatment, immersed in a solvent, and pyrolyzed and calcined to obtain an isotropically shrunk three-dimensional micro-nanostructure.
