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.
Intermolecular forces such as Van der Waals forces, hydrogen bonds, and dipole–dipole interactions are typically not sufficiently strong to hold two apparently conformal rigid bodies together, since the forces drop off rapidly with distance, [2] and the actual area in contact between the two bodies is small due to surface roughness and minor imperfections.
Cyanoacrylate adhesives may adhere to body parts, and injuries may occur when parts of the skin are torn off. [27] [28] Without force, however, the glue will spontaneously separate from the skin in time (up to four days). The glue can also cause chemical burns, and exposed skin should be washed with soap and warm water. [29]

Impact glue, contact glue, contact cement, or neoprene glue is a type of solvent-based adhesive which may be used to bond materials such as plastics, laminates, and metal or wood veneers. [1] The term "contact glue" come from the practice of applying adhesive to both surfaces to be bonded; the surfaces are joined once the solvent in the ...
There are two types of adhesives that harden by drying: solvent-based adhesives and polymer dispersion adhesives, also known as emulsion adhesives. Solvent-based adhesives are a mixture of ingredients (typically polymers) dissolved in a solvent. White glue, contact adhesives and rubber cements are members of the drying adhesive family. As the ...
