Super Glue, Krazy Glue, are names given to glues with a base called cyanoacrylate. There are dozens of these types of glues, with different stregths, viscosities(how thick or liquidy the product is) and many other varying qualities. Companies like Loctite have so many different types it is hard to keep track of.
Commercial types of cyanoacrylate became available to the general public about 20 years ago. Up to that point most would buy a tube of super glue or Krazy Glue and get to only use it once if that. Bottles of a commercial grade cyanoacrylate showed up mostly at trade shows, like home shows, fishing and boating shows and similar venues. One could see demonstrations of the glue bonding almost anything to anything.
These products(like Mister Glue) have been around for decades but now can be purchased in smaller amounts and can be used safely around the home or shop.
Cyanoacrylates react to minute amounts of moisture on the surface of the material that you are gluing. (No, wetting the surface is not a good idea.) I have seen some demonstrators claim that their glue reacts when you remove the oxygen. This would be called an "anaerobic glue". It appears that way as they are so quick to bond. BUT those claiming this do not understand the chemistry of cyanoacrylates. It is the surface moisture that they react to. Products that you may have seen that are cyanoacrylates and react to moisture are Mister Glue, Max One, The Last Glue, Miracle Glue, Super Glue and Krazy Glue. They are NOT anaerobic glues. The real point though is that these commercial versions of super glue are fantastic products.
