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.
The image is face-mounted and stuck to the acrylic glass with a special sealant. Normally the mounted print is then placed on a carrier sheet. This is usually Aluminum. If the print has to be backlit, translucent materials such as acrylic can be used instead. The Diasec gel is neutral curing and has an inbuilt ultraviolet filter.
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde.
There are a wide variety of adhesives used for optical bonding processes. Three of the most commonly used are silicone, epoxy, and polyurethane. [1] Below are overviews of the pros/cons of each adhesive type. Silicone: The most commonly found adhesive in optical bonding processes that dates back to the 1970s as a solution.
The original patent for cyanoacrylate was filed in 1947 by the B.F. Goodrich Company [2] as an outgrowth of a search for materials suitable for clear plastic gun sights for the war effort. In 1942, a team of scientists headed by Harry Coover Jr. stumbled upon a formulation that stuck to everything with which it came in contact. [3]
Acrylic resin as pressure-sensitive adhesive. "Super glue" is a formulation of cyanoacrylate. Polymethyl methacrylate is the clear break-resistant sheeting sold as acrylic glass (or simply acrylic sheet) or under the trade name Plexiglas, Perspex, etc.
