This non-toxic, colorless, extremely fast-acting, strong adhesive in its pure form, can lift pounds per square inch. Over , uses for glue were sent in by customers. An example of one usage was when a college student cut their hand and should have gone to the hospital to get stitches but instead they used Krazy glue was used to seal the skin up.
Not so farfetched because during the Vietnam War, cyanoacrylate was proven valuable to military surgeons. Under battlefield conditions, they used it to stop bleeding and even close wounds. In , cyanoacrylate was rediscovered by Coover and Dr. Fred Joyner. Coover was now supervising research at the Eastman Company in Tennessee. Coover and Joyner were researching a heat-resistant acrylate polymer for jet canopies when Joyner spread a film of ethyl cyanoacrylate between refractometer prisms and discovered that the prisms were glued together.
Coover finally realized that cyanoacrylate was a useful product and in the Eastman compound was marketed and later packaged as superglue. Hot glue or hot melt adhesives are thermoplastics that are applied hot often using glue guns and then harden as they cool.
Hot glue and glue guns are commonly used for arts and crafts because of the wide range of materials that hot glue can stick together.

Select personalised content. It was discovered that cyanocrylate could be used in forensics. Fumes from the adhesive reacts with fingerprints and forms a white residue that reveals fingerprints on smooth surfaces.
These various applications of Krazy Glue demonstrates how specific uses for an invention can be discovered after it has been patented. Dermabond Kodak and a pharmaceutical company Ethicon got together to research how cyanoacrylate glue could be used for bonding skin.
During the Vietnam war, a cyanoactylate spray was used by medics to prevent wounded soldiers from bleeding to death. According to Coover, soldiers suffering open wounds during battle would often bleed to death before they got to a base hospital.
I asked what happened and he said that he cut it with a carpet knife accidentally and that instead of using a band-aid or other typical first-aid-type product, he sealed it with super glue.
When I sounded surprised at this, he told me that his doctor had told him once that super glue came about during Vietnam as a means of quickly closing wounds on the front lines where troops were under fire and had no time to bandage wounds in a more traditional manner.
It sounds plausible--after all it does say that it "bonds skin instantly. Super glue, Krazy glue, Eastman and similar glues are all a special type of glue called cyanoacrylates. Cyanoacrylates were invented in by Dr. Harry Coover of Kodak Laboratories during experiments to make a special extra-clear plastic suitable for gun sights. Six years later he pulled it out of the drawer thinking it might be useful as a new plastic for airplane canopies. Wrong again—but he did find that cyanoacrylates would glue together many materials with incredible strength and quick action, including two very expensive prisms when he tried to test the ocular qualities of the substance.
The use of cyanoacrylate glues in medicine was considered fairly early on. Eastman Kodak and Ethicon began studying whether the glues could be used to hold human tissue together for surgery. Soon afterward Dr. According to an interview with Dr.
