Cyanoacrylate is the generic name for cyanoacrylate based fast-acting adhesives commonly sold under trade names like SuperGlue and Krazy Glue, veterinary glues Vetbond and LiquiVet and medical grade skin glues LiquiBand, SurgiSeal, FloraSeal, Dermabond, and Nexaband. Cyanoacrylate adhesives are sometimes known as "instant glues". The abbreviation "CA" is commonly used for industrial grades.

Cyanoacrylate is a tenacious adhesive, particularly when used to bond non-porous materials or those that contain minute traces of water. It is also very good at bonding body tissue, and while this can be a bothersome (or even dangerous) side effect during everyday use, it has been exploited for the benefit of suture-less surgery.

Cyanoacrylates were invented in 1942 by Dr. Harry Coover and Fred Joyner of Kodak Laboratories during experiments to make a special extra-clear plastic suitable for gun sights. Although not appropriate for the gun sights, they did find that cyanoacrylates would quickly glue together many materials with great strength. Seeing possibilities for a new adhesive, Kodak developed "Eastman #910" (later "Eastman 910") a few years later as the first true "super glue."
