  • Publication number: 20180327297
    Abstract: A method for producing a glass article includes forming a glass sheet from a molten glass source and separating the glass article from the glass sheet. During the step of separating the glass article from the glass sheet, the water content of the atmosphere surrounding the glass sheet is controlled to be below a predetermined value. Such control of the water content of the atmosphere surrounding the glass article can effectively reduce the density of particles adhered thereto.

  • Publication number: 20180297889
    Abstract: Disclosed herein are methods for treating a glass substrate, comprising bringing a surface of the glass substrate into contact with at least one surface treatment agent for a time sufficient to form a coating comprising the at least one surface treatment agent on at least a portion of the surface. Also disclosed herein are glass substrates comprising at least one surface and a coating on at least a portion of the surface, wherein the coated portion of the surface has a contact angle ranging from about 20 degrees to about 95 degrees, and/or a contact angle greater than about 20 degrees after contact with water, and/or a contact angle less than about 10 degrees after wet or dry cleaning of the glass substrate.

  • Patent number: 9434641
    Abstract: A method for protecting a sheet surface by forming a discontinuous layer of a long-chain organic material having a main carbon chain comprising at least 12 carbon atoms and a hydrophilic group at one end of the main chain on the sheet surface. The protective layer is easy to remove using standard cleaning method, while providing satisfactory surface protection against particle contamination and scratches, at a very low coating thickness. The invention is particularly useful for protecting glass sheet surfaces during glass sheet finishing such as edge grinding and polishing. The invention is especially useful for the finishing and packaging of LCD glass substrates.
