Cyanoacrylate is the generic name for a family of fast-acting adhesives with industrial, medical and household uses. They include methyl 2-cyanoacrylate, ethyl-2-cyanoacrylate (commonly sold under trade names like "Super Glue" and "Krazy Glue"), and n-butyl cyanoacrylate (used in veterinary and skin glues). The related compound 2-octyl cyanoacrylate is a medical grade glue; it was developed to be non-toxic and less irritating to skin tissue. Cyanoacrylate adhesives are sometimes known as instant glues. The abbreviation "CA" is commonly used for industrial grades. The original cyanoacrylates (the chemical name for the glue) were discovered in 1942 in a search for materials to make clear plastic gun sights for the war, when a team of scientists headed by Harry Wesley Jr stumbled upon a formulation that stuck to everything that it came in contact with. However, cyanoacrylates were quickly rejected by the American researchers precisely because they stuck to everything.
