Optical bonding is the use of an optical-grade adhesive to glue a glass to the top surface of a display. The main goal of optical bonding is to improve the display performance under outdoor environments. This method eliminates the air gap between the cover glass and the display. [2]
Liquid optically-clear adhesive (LOCA) is liquid-based bonding technology used in touch panels and display devices to bind the cover lens, plastic, or other optical materials to the main sensor unit or each other. These adhesives improve optical characteristics and durability. LOCA glue is often hardened using ultraviolet light.
If a sculpture is broken into several pieces, art conservators may reattach the pieces using an adhesive such as Paraloid B-72 or epoxy. If the sculpture is made of a transparent or semitransparent material (such as glass), the seam where the pieces are attached will usually be much less noticeable if the refractive index of the adhesive ...
As envelope adhesive. As wallpaper adhesive. As a primer for drywall and other substrates. As a gum base in chewing gum. [8] As a water-soluble support material for 3D printing, usually for the fused filament fabrication method. [9] As an adhesive for cigarette paper. [10] As the coating layer on Gouda cheese. [11]
The disadvantage of the lack of instantaneous bonding exhibited by many adhesives can be overcome by using a suitable fast-curing adhesive or a combination of a standard adhesive with a second, fast-curing adhesive (e.g. double-sided adhesive tape) or with another joining method, such as spot welding, rivets, screws, or clinching / press ...
Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
