Super Glue was Invented by Accident, Twice - 0 views

super glue invented by accident

shared by Shelby Tenney on 09 Jan 14 - No Cached
  • Super Glue, also known as cyanoacrylate, was
  • originally discovered in 1942 by Dr. Harry Coover, who by the way died last month on March 26th, 2011
  • Nine years later, in 1951
  • ...8 more annotations...
  • Coover was attempting to make clear plastic gun sights to be put on guns used by Allied soldiers in WWII.  One particular formulation he came up with didn’t work well for gun sights, but worked fantastically as an extremely quick bonding adhesive.  Surprisingly, despite the commercial potential of such a product, Coover abandoned that formulation completely as it obviously wasn’t suitable for his current project, being too sticky.
  • canopies
  • for jet canopies
  • 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.
  • 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”.
  • Note: It should be noted here that while Super Glue was originally invented by accident thanks to WWII, it was not, as a popular urban legend tells, accidentally discovered by soldiers in WWII who then subsequently began using it to seal up battle wounds.  Rather, it was discovered as described above and didn’t hit the public market until well after WWII had ended
  • Interestingly though, according to its creator, Dr. Harry Coover, Super Glue actually was used  in the Vietnam War to help close up wounds on soldiers while they were being transported to hospitals to then receive stitches.  Today, a form of cyanoacrylate is often used in place of or in conjunction with traditional sutures.

Accidental Invention of The Post-It® Note - 0 views

shared by justin creed on 10 Jan 14 - No Cached
  • In 1968 a 3M scientist developed a reusable adhesive that didn't really stick. The glue he created could hold paper together, but wasn't strong enough to maintain the bond when pulled on. Unfortunately, the scientist was trying to make a super glue. It would take 12 years and a flash of 'eureka' to turn the glue that wouldn't stick into the Post-It Note.
  • While trying to improve the adhesive that 3M used for tape, Silver discovered a less sticky glue. Ordinary adhesives are flat, with a solid contact area for adhesion. It is this unbroken contact that makes glue so sticky. What Silver found was a glue that while quite sticky, could only be formed into individual spheres the thickness of a piece of paper. The spheres would only adhere to things tangentially, thus, the adhesive's total contact area was very small. The result was a tacky, reusable glue that held paper together well. Silver knew he was on to something, but wasn't sure how to market it.
  • In attendance at one of these seminars was a 3M scientist named Arthur Fry. Fry sang in his church choir, and to keep track of the hymns, he tore scraps of paper into strips to make bookmarks. Every Sunday a few would fall out of the hymnal, frustrating Fry. In a moment of 'divine' inspiration, Fry realized that Silver's glue might make the perfect temporary adhesive to hold bookmarks! At work, Fry gathered
  • ...5 more annotations...
  • scraps of paper and Silver's glue, and combined them to make sticky, but removable bookmarks. The bookmarks were popular and handy, but people didn't need more than a few of them.
  • In 1978 a team of 3M marketers flooded Boise, Idaho, showing everyone they could find the wondrous new notes. Post-It Notes were officially released to the public in 1980, and in 1981 they were named 3M's Outstanding New Product. Today there are over 600 products based on the Post-It concept. Arthur Fry is semi-retired from 3M, maintaining a part-time presence as a mentor. Spencer Silver retired in 1996.
  • When it became clear that Post-It Notes were viable in a commercial atmosphere, 3M's marketing went to work.
  • Fry quickly realized that his bookmark had applications as an adhesive note. Fry believed so strongly in his invention that when engineers told him that a machine didn't exist to manufacture the notes, he went home and built just such a machine in his basement. When he couldn't fit it through his basement door, he knocked the wall down. Now he had his manufacturing equipment, and a great product. The only thing he didn't have was the support of senior management at 3M. To overcome this, Fry sent samples of his notes to all the company's executives, who quickly ordered more samples. Management was quickly hooked, and their demand soon outstripped development's production capacity.

  • (NewsCore) - The man who invented Super Glue has died in Tennessee at the age of 94, The New York Times reported Sunday. Harry Wesley Coover Jr., who discovered the super-sticky adhesive by accident during World War II, died of congestive heart failure Saturday night at his home in Kingsport. Inducted into the National Inventors Hall of Fame in 2004, Coover was awarded the National Medal of Technology and Innovation last year by President Barack Obama. Super Glue did not make him rich, however, as it did not become a commercial success until the patents had expired. Son-in-law Dr. Vincent E. Paul said, "He did very, very well in his career but he did not glean the royalties from Super Glue that you might think."

  • They began in 1980, when a St. Paul, Minnesota, choir member's hymnal bookmarks kept falling to the floor. Chorist Arthur Fry, an engineer at chemical company 3M, joined forces with 3M scientist Spencer Silver, inventor of a peculiar adhesive that stuck poorly to surfaces. The glue provided perfect temporary fixes for paper scraps such as hymnal bookmarks
  • One year after 3M officially launched the Post-it Note, the packs of sticky paper raked in more than US$2 million in sales. Post-it Notes - available in 27 sizes, 57 colors, and 20 fragrances
  • In the 1940s, a Belgian chemist mixed carbolic acid and formaldehyde to create the first synthetic adhesive. Post-it Notes use a more recent innovation: Unlike the typical, featureless adhesive surface, the Post-it Note glue coats the notes with bumpy microspheres that limit the sticky area. The adhesive mostly consists of alkyl acrylate, a volatile liquid that dissolves slightly in water and completely in alcohol. More detailed ingredients remain private. The paper used to make Post-it Notes is certified by the Sustainable Forestry Initiative, a system founded by the U.S. paper industry. Although SFI certification ensures that a company has an environmental management system in place, most environmental groups prefer the international non-profit Forest Stewardship Council's more stringent performance-based environmental and social indicators.
