Many fellow tweeps, on Twitter, are posing this question on-line: Why doesn’t Super Glue stick to the inside of the tube? According to our on-site lab senior scientist the answer: Chemistry. Super Glue Corporation searches the world over to find metal tubes that are chemically compatible with our cyanoacrylates (also known as CAs or super glues). As long as no air, moisture, or other contaminants are present, and the metal in the metal tube is compatible with the super glue, then the super glue remains liquid throughout its shelf life.
Additionally, Super Glue Corporation uses custom resins for all super glue caps, tips, and bottles to ensure that caps won’t stick to the the super glues. If they ever do stick (once in awhile this might happen after a first use, when excessive amounts of a thicker viscosity gel super glue overflows into the cap) using a disposable towel moistened with acetone, to remove excess super glue, will quickly resolve that sticky issue, and the cap will twist on and off like new.
