The emergence of superglue is an exciting thing. It solves various bonding problems for humans. In fact, super glue was discovered by accident.

In 1942, Dr. Harry Coover was making transparent plastic gun sights. Found that a formula can stick to everything that comes into contact. But this discovery did not help in making plastic gun sights, so he quickly abandoned his discovery.

In 1951, when Eastman Kodak researchers Harry Coover and Fred Joyner created the heat-resistant jet canopy, cyanoacrylates were re-discovered that Coover had created and decided to test it by spreading a layer of ethyl cyanoacrylate between two refractors prisms which quickly became bonded. It was now that Coover recognized the commercial value of the cyanoacrylate adhesive. and pushed forwards with his invention.


In 1958, Super Glue entered the market, initially called "Eastman 910", and later sold under the trade names "Super glue" and "Krazy glue".


In 1970, many adhesive manufacturers used Coovers cyanoacrylate formula to produce super glues, built their own brands, and sold super glues of their own brands.



In the beginning, this super glue was only used to bond objects of various materials and was not used on humans or animals.


In 1966, a professional surgical team conducted a field test on cyanoacrylate and found that this glue would not Degum due to the presence of blood or water, on the contrary, it will polymerize to form a seal, showing excellent hemostatic ability.

During the Vietnam War, Coover developed a disposable cyanoacrylate spray as a hemostatic agent. At that time, this cyanoacrylate spray saved many lives. Soldiers were injured on the battlefield and needed to stop bleeding immediately and be sent to the hospital. Otherwise, he will lose too much blood and die.


Today, this medical-grade superglue (n-butyl cyanoacrylate) is a liquid topical skin adhesive and is now approved for superficial wounds. It is suitable for suture lacerations within 5-0 on the face, arms, legs, and torso. It is widely used in circumcision surgery in Indonesia; it can also be used for wound healing and sterilization of animals.
