37 Fun Facts Where Does Super Glue Come From | where did super glue come from
- Super glue, that is a chemical compound, was accidentally invented by Dr Harry Coover in 1942. During World war 2, he was working on making clear plastic lenses to precise gun sights for soldiers. Unfortunately, cyanoacrylate(CA) was excluded as a material since it was extremely sticky. However, after 6 years, he realized that this chemical permanently glues anything. This chemical, CA, is what we know as super glue. - Source: Internet
- Glue is a gelatinous adhesive substance used to form a surface attachment between discrete materials. Currently, there are five basic types of glue. Solvent glues comprise an adhesive base mixed with a chemical solvent that makes the glue spreadable; the glue dries as the solvent evaporates. Most solvents are flammable, and they evaporate quickly; toluene, a liquid hydrocarbon made from fossil fuels, is often used. Included in this category are glues sold as liquid solders and so-called contact cements. - Source: Internet
- Cyanoacrylate is an acrylic resin that forms its strongest bond almost instantly. The only thing it requires to set is water. Since almost every object has at least tiny amounts of water on its surface, super glue does a super job of sticking most things together very quickly. - Source: Internet
- Some rock climbers use cyanoacrylate to repair damage to the skin on their fingertips. Similarly, stringed-instrument players can form protective finger caps (in addition to calluses) with cyanoacrylates. While the glue is not very toxic and wears off quickly with shed skin, applying large quantities of glue and its fumes directly to the skin can cause chemical burns. - Source: Internet
- The original super glue is not allowed to use to heal the cuts officially. But there is an alternative that was invented for a medical purpose. In 1998, FDA approved a 2-octyl-cyanoacrylate, an improved medical adhesive that was less irritating. As commercializing this new safer medical adhesive, we can expect fast recovery without stitching. - Source: Internet
- Over a decade later, Coover, who would become known as “Mr. Super Glue,” rediscovered the adhesive compound while researching heat-resistant polymers for jet canopies. Cyanoacrylate adhesives required no heat or pressure to stick items together and hold them permanently. Thus, in 1956, the patent for “Alcohol-Catalyzed Cyanoacrylate Adhesive Compositions/Superglue” was born. How’s that for a name? - Source: Internet
- The main ingredient in super glue is cyanoacrylate which is clear gel-like liquid. CA is acrylic resin rapidly polymerized when it reacts with hydrogen that is represented as ‘Nu+’ in the picture. When its exposure in presence of water, then it makes stronger and longer chain which is called poly-cyanoacrylate. Through this reaction, it transforms from liquid to solid, from the surface to deep inside. Due to humidity in the air, it can also explain why the glue harden when you forget to close the cap after use it. - Source: Internet
- On March 6, 1917, American chemist and inventor Harry Wesley Coover Jr was born. He is best known for having invented Eastman 910, better known as super glue. Super Glue is based on cyanoacrylates, a family of strong fast-acting adhesives with industrial, medical, and household uses. - Source: Internet
- Super glues typically come in liquid or gel forms. Liquids are best for penetrating cracks or fractures and generally dry faster than gels. Gels create a more flexible bond than liquids and their higher viscosity means less dripping, offering a more controlled application for projects requiring greater precision or vertical application, like building models or fixing delicate flatware. Loctite offers a range of super glues in both liquids and gels, customized for every job. - Source: Internet
- The cyanoacrylates actually have more uses that just in super****glue. Some of them can also be used to help stick wounds together, particularly in combat situations where temporary fixes for lacerations until stitches can be put in are often necessary. Different members of the compound class which are less irritating to the skin are used for this, such as 2-octyl cyanoacrylate. Cyanoacrylates can also be used in dentistry, to create some types of fillings. - Source: Internet
- Quality super glues come in a variety of application designs. Some use a patented side-squeeze design for a more precise utilization, even in tough-to-reach areas. Liquid-based super glue products feature a narrow nozzle for controlled and drip-free application and an easy-to-open cap with a metal pin for clog-free usage. - Source: Internet
- At this time, the chemical was not yet approved by the Food and Drug Administration because it had the potential to cause skin irritation. A derivative from the same chemical (2-octyl-cyanoacrylate) was approved in 1998 and functioned as a liquid bandage. Marketed under the names Dermabond and Traumaseal, these products pose less danger of irritation and bacterial infection and are available for civilian use. - Source: Internet
- But the adaptation of Super Glue by medics brought the change that was desperately needed. Super Glue served as a tissue adhesive which effectively saved wounded soldiers from bleeding to death: once applied on the bleeding injury, within seconds the broken skin would seal up and the bleeding would stop. Then, the wounded soldier would be taken to a hospital for proper medical care. - Source: Internet
- The polymer super****glue forms is very strong, making the glue very difficult to tear apart once it has set. Intermolecular forces (such as Van der Waals forces) between the glue and the surfaces you’re attempting to stick together help hold it in place. Mechanical binding also plays a part: the glue can seep into small cracks and pores on the surfaces being stuck together, and when it solidifies this too becomes very difficult to pull apart. In truth, we still don’t know all of the details when it comes to understanding how glues stick surfaces together; though we have a general idea of the forces involved, the nature of these forces for particular glues still isn’t fully understood. - Source: Internet
- 4 Because the monomers are lighter than the polymer, they volatize upward and are piped out of the kettle into a second collector. The process is not unlike distilling, although the goal is a glue rather than an alcoholic beverage. In going from one vessel to the other, the monomers move through a series of cooling coils that allow them to become liquid. A second distilling might be performed for a high-quality product, and some manufacturers might even distill the monomers a third time. - Source: Internet
- So, how do the cyanoacrylates lend super****glue its stickiness? Simply put, these compounds can react with small amounts of water – even the amount of water present as water vapour in the air is enough to initiate a reaction. The reaction between a cyanoacrylate and water produces an intermediate ion which can go on to react with more cyanoacrylate molecules, eventually created a long chain of them all connected together – a polymer. This is different from many other glues, which form a bond as the solvent they are carried in evaporates. - Source: Internet
- Dear Straight Dope: I was talking to my brother-in-law the other day and noticed that he had a fairly bad cut on his hand, but it looked kind of weird. 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.” Is this true or just an urban legend? Scott Matheson - Source: Internet
- Everyone has used for super glue at least once when fixing a broken object. This plastic glue was not only used for the quick fix but also a medical product that saved lots of patients on the battlefield. Moreover, the interesting fact that reported by The Newyork Times, is that today professional athletes also use the super glue to seal their shallow cuts. - Source: Internet
- Superglue was initially discovered by accident. Dr Harry Coover, a researcher at Kodak laboratories, was trying to develop clearer plastics for use as gunsights during the Second World War when he stumbled across cyanoacrylates, the class of chemicals used in super****glue. However, due to their tendency to stick to absolutely anything, they were discarded as useless. - Source: Internet
- Super Glue (cyanoacrylate glue) is not actually a poisonous substance, but it is still extremely dangerous for your dog. If your dog ingests cyanoacrylate glue, it causes irritation, vomiting, coughing, and it may cause parts of your dog’s gums to be sealed shut. If swallowed, this glue can become a large mass in your dog’s esophagus, stomach, or intestines. While this may not be life-threatening at first, swallowing the glue that comes loose from the mouth or skin can cause an obstruction that can be fatal. If your dog has ingested or chewed on Super Glue, it is best to make a trip to the veterinarian quickly to be on the safe side. - Source: Internet
- Water-based glues use water as a solvent instead of chemicals. They work slower than chemical solvent glues; however, they are not flammable. This category comprises such glues as white glue and powdered casein glue, made from milk protein and mixed at home or in the shop. - Source: Internet
- Super Glue really is “super”. A one square inch bonding of Super Glue can hold around one ton. In fact, Super Glue has even been used to bond a small surface area of metal attached to a crane, which was then glued to the top of a car. The car was then lifted successfully by the crane without the bond breaking. - Source: Internet
- The story of super****glue might have ended there, but Coover was also involved in the rediscovery of cyanoacrylates several years later. This time, it was during research in the early 1950s into flame-resistant polymers for use in jet canopies. A research student working under Coover synthesised ethyl cyanoacrylate, and, in trying to measure the compound’s refractive index, accidentally stuck two glass prisms together. This time around, Coover realised the potential of the cyanoacrylates, and they were eventually developed into a super-adhesive glue that was made available commercially in 1958. - Source: Internet
- Super Glue was finally put on the market in 1958 by Eastman Kodak and was called the slightly less catchy name of “Eastman #910”, though they later re-named it “Super Glue”. Eastman #910 was soon licensed to Loctite who then re-branded it again to a somewhat uninspired name of “Loctite Quick Set 404”. Although, they later developed their own version, calling it “Super Bonder”. By the 1970s, numerous manufactures of cyanoacrylate glues had popped up, with Eastman Kodak, Loctite, and Permabond accounting for around 3/4 of all “Super Glue” sales. - Source: Internet
- Cyanoacrylate glues were discovered at a Kodak lab in 1951 when two chemists, Dr. Harry Coover and Dr. Fred Joyner, tried to insert a film of ethyl cyanoacrylate between two prisms of a refractometer to determine the degree to which it refracted, or bent, light passing through it. Though the first conclusion of Coover, Joyner, and the other members of the lab team was only that an expensive piece of laboratory equipment had been ruined, they soon realized that they had stumbled upon a new type of adhesive. - Source: Internet
- Super glue was invented in 1942 by Dr. Harry Coover. He was part of a wartime research team at Eastman Kodak that developed clear plastics for use in precision gun sights. Coover and his colleagues unintentionally discovered a chemical compound of extraordinary stickiness, but they initially saw no use for it in their research. - Source: Internet
- While Super Glue + cotton or wool can create enough heat to cause a flame, Super Glue + other materials also will cause heat. This is thanks to the process of anionic polymerization that the glue undergoes as it bonds. Because of this, if you put enough Super Glue on your finger, you can actually burn yourself that way too, without any other materials necessary. - Source: Internet
- Two part glues include epoxy and resorcinol, a crystalline phenol that can be synthesized or made from organic resins. One part contains the actual glue; the other part is a catalyst or hardener. Two part glue is very useful for working with metals (automobile dent filler is a two part glue) but must be mixed properly to work well. - Source: Internet
- This phenomenon explains why a thin film of C.A. glue works better than a thicker one. A thinner glue can be squeezed so close to the material it is bonding that the electromagnetic force takes over. A thicker film permits enough space between the materials it is bonding so that the molecules can repel one another, and the glue will consequently not hold as well. - Source: Internet
- Nine years later, in 1951, now working at Eastman Kodak, Dr. Coover was the supervisor of a project looking at developing a heat resistant acrylate polymer for jet canopies. Fred Joyner was working on that project and at one point used the rediscovered Super Glue and tested it by spreading ethyl cyanoacrylate between a pair of refractometer prisms. To his surprise, the prisms became stuck very solidly together. This time, Coover did not abandoned the cyanoacrylate (Super Glue), rather, he realized the great potential of a product that would quickly bond to a variety of materials and only needed a little water to activate, which generally is provided in the materials to be bonded themselves. - Source: Internet
- Loctite super glues come in a variety of specialized applicator styles meant for every application, no matter how awkward. The applicator of Loctite Super Glue Ultra Liquid Control has a patented side-squeeze design for more precise gluing, even in tough-to-reach areas. The Longneck Bottle features a precision tip for controlled, drip-free, drop-by-drop application and an easy-open cap with a metal pin for clog-free usage. - Source: Internet
- The reaction with water is also the reason that getting super****glue onto your skin can easily end badly. As your skin contains moisture, it too can set off the polymerisation reaction. There’s a very good reason why super****glue packets warn you not to get it anywhere near your eyes or mouth! - Source: Internet
- C.A.s are produced in heated kettles that can hold from a few gallons to several thousand gallons; the size depends upon the scale of the particular manufacturing operation. - Source: Internet
- Super glues typically come in liquid or gel forms. Liquids are best used for cracks or fractures and generally dry faster than gels. Some gels, like LePage Super Glue Ultra Gel Control, create a more flexible bond than liquids. Their gel consistency means no dripping, offering a more controlled application for projects requiring greater precision or vertical application. - Source: Internet
- The finished product also is tested before shipping. Most important is shear resistance, a measure of the force necessary to break the holding power of the glue. Measures of shear strength commonly reach several thousands of pounds of force per square inch. - Source: Internet
- In its liquid form, cyanoacrylate consists of monomers of cyanoacrylate molecules. Cyanoacrylate itself is an acrylic resin which rapidly polymerizes in the presence of water. It forms long and strong chains and joins the bonded surfaces together. Cyanoacrylate is further used as a forensic tool to capture latent fingerprints on non-porous surfaces like glass as well as plastic. Cyanoacrylate glue was in veterinary use for mending bone, hide, and tortoise shell by the early 1970s or before. - Source: Internet
- Is it safe to use ordinary household cyanoacrylate glue as a medical glue? According to Reference 7, most cyanoacrylate glues not designed specifically for medical use are formulated from methyl-2-cyanoacrylate, since it produces the strongest bond. Not only can such glues irritate the skin, during polymerization they can generate significant heat, to the point of causing skin burns. I gather this is a problem only if a large area of skin is affected. But to err on the side of safety, you should tell your brother-in-law he should only use medically-approved glue, not the ordinary kind. And always be careful using it–I know families are supposed to stick together, but there are limits. - Source: Internet
