Abstract:
A process and system for applying coating materials to glass edges of various profiles. The glass edge is coated by picking up the coating material from an applicator such as, for example, a roller, through precise independent or relative control of the spatial relationship between the edge of the glass article and the applicator to achieve desirable product attributes such as coating thickness, profile, coverage areas and consistency. Such spatial relationships include the gap distance between the roller and applicator, coating thickness on the applicator, applicator and/or glass speed, and the like.
Abstract:
This disclosure features a method of protecting glass sheets from scratching and staining. A first surface of polymer film is positioned in contact with a major surface of a glass sheet. An additional glass sheet is placed against the polymer film such that a major surface of the additional glass sheet contacts a second surface of the film. Both of the first and second surfaces of the film have a peel value of less than 50g relative to the glass sheets and a surface roughness Ra of greater than 0.5 micron. The method will prevent scratches on a glass surface from the bottom of the draw, during shipment between glass forming plants, as well as during shipment and handling in connection with customers of glass processing plants.
Abstract:
A method is described herein for packaging a plurality of glass sheets by: (1) coating a top surface of each glass sheet with a removable top protective film; (2) coating a bottom surface of each glass sheet with a removable bottom protective film; and (3) stacking the coated glass sheets next to one another such that the top protective film of one glass sheet is adjacent to the bottom protective film of another glass sheet. The top protective film and/or bottom protective film on each glass sheet has embossed features (e.g., rough features) formed therein which make it easier to separate one glass sheet from one another glass sheet because of the presence of air pockets caused by the embossed features located between the stacked glass sheets. The coated glass sheet and a container that can store a plurality of the coated glass sheets are also described herein.

Abstract:
This disclosure is directed to a continuous flow ion-exchange system and process (CIOX) in which a fresh molten salt, for example KNO 3 , is supplied a salt inlet end of a long channeled containment vessel and the used molten salt is removed from a salt outlet end distal from the inlet end of the channel. Glass article is loaded into at least one cassette, the cassette is placed in the vessel containing the molten salt and is translated from the salt outlet end to the salt inlet end. Cassettes containing glass articles are continuously placed into the vessel at the salt outlet lend and are removed as they reach the salt inlet end.
Abstract:
A protective paper or film and a method of protecting a glass substrate by applying the protective paper or film having a slip agent composition onto a surface of a glass substrate. The slip agent composition comprises at least one fatty alcohol as defined herein.
