Glue is one of the most inexplicable items of human life. Starting from the glue paper, wood glue, glue iron, and berbegai other types of glue. However, among all types of glue, there is one that has usability in many areas. The glue is super glue or also known as power glue or krazy glue. Super glue is used in various fields, ranging from for electronic purposes, aquarium, feorensik, wood, medical, to cosmetics. In other words, this super glue has penetrated into various fields. But, you know, this glue turned out to be a failed discovery.
Called failed because initially, the inventor of Harry Coover does not intend to make glue. In 1942, Coover had wanted to make a pistol pointing material of clear plastic. For that purpose, Coover and his team at Eastman Kodak examined cyanoacrylates. Unfortunately, this material is too sticky that it can not be used as the initial aim of the gun. Nine years later, Coover watched the Kodak chemists who wanted to make polymers for heat-resistant jet canopies. The team is back using cyanoacrylates. The results again show the material is too sticky. Over the course of time, Coover realized that he had found a unique adhesive. New in 1958, this adhesive is then marketed by Kodak under the name Super Glue. This adhesive then became famous during World War II. Initially, this super glue is used to repair pottery and clothing.
Furthermore, super glue ogled to be applied in the medical field. During the Vietnam war, the super glue became a lifesaver. “If a person has a large chest wound or open wound the biggest problem is stopping the bleeding so that it can take him to the hospital,” Coover told Kingsport Times News quoted from Popular Mechanics, February 2017.
“Many of the injured people died of blood loss, so medical personnel used a glue spray to stop the bleeding and take them to the hospital, saving lives,” Coover said. Although spelled out to save many lives, the US Food and Drug Administration (FDA) does not approve of the use of super glue in the medical field. The reason is, these super glue compounds can cause skin irritation that can develop into a serious problem. Surely this is then trigger the researchers found super glue for medical purposes. Several studies later proved that cyanoacrylates material could be safer and functional at wound closure than traditional sewing (wound sewing). In fact, this glue is said to be superior in the time it takes to close the wound, infection, and the end result on the skin. Not only that, inspired by the power of this super glue, Australian researchers also developed a similar new substance. “Just spray it (the glue) to the wound, even if it’s lung damaged or broken blood vessels or torn,” said Professor Anthony Weiss, professor of biochemistry at the University of Sidney.
As mentioned, the use of super glue almost touches all areas. One of them is forensic. Cyanoacrylate is used as a forensic tool to capture a latent fingerprint on a non-porous surface such as glass, plastic, and so on.
When warmed, this material produces smoke that reacts with invisible fingerprint residues. When the smoke meets with atmospheric moisture it forms a white polymer (polycyanoacrylate) on the fingerprint bulge. The bulge was then recorded. Fingerprints developed, on most surfaces (except on white plastic or something) can be seen with the naked eye. If the prints are not visible or bad, we can also increase their visibility by applying luminescent or non-luminescent coloring.
Super glue is also commonly used for aquariums. This is because of this super glue difference with the glue usually. If the glue usually attaches from the evaporation of the water of the object, then super glue would glue the object when interacting with water. The super glue bonding process is triggered because of hydroxyl ions (OH-) from water. Water here can come from the surface of objects in glue and humidity.
Super glue is also used in the beauty or cosmetics industry. This glue is usually used as a nail glue on artificial nails.
