GLASS SUBSTRATE ADHESION CONTROL

Abstract:

Methods of processing or modifying a glass substrate such as a glass sheet are disclosed. A method includes contacting at least one of opposing major surfaces of the glass sheet with a fluid applicator apparatus and a liquid etchant composition including acetic acid, ammonium fluoride, and water, the contacting conducted at a predetermined transfer rate of the liquid etchant to the at least one of the opposing major surfaces. The predetermined liquid transfer rate is controlled to adjustably texture the at least one of the opposing major surfaces and provide a textured major surface, wherein when the textured major surface and a planar surface are placed in contact, there is an adhesion force between the textured major surface and the planar surface, and wherein the adhesion force is within a target adhesion force range.
