The reason it doesn't get stuck in the tube is the same reason a box of doughnuts aren't hard as hockey pucks when you first open the package. For superglue to work it needs air to make it hard, just like the doughnut. The chemicals react with oxygen to change the chemical structure so it becomes hard and sticks to whatever it can. With the doughnut, the water is pulled out by the rest of the air in the room and it becomes hard. We're taught in high school chemistry that things go from HIGH-LOW. The more dramatic the diff and the easier it can move from HIGH - LOW, the faster the change will happen.
Hope this makes sense Super glue cures in the presence of hydroxyl ions in water. No water or water vapor in the tube of super glue will keep the nozzle clog free.

∙ 13y agoGlue is made up of a substance that sticks to things and a solvent that keeps it liquid until you want it to stick. When you put glue on a piece of paper, the solvent gradually evaporates until the glue becomes sticky. When the glue is in a bottle, there is a space inside the bottle above the liquid that is full of air. So why doesn't the glue dry out? Well there's a limit to the amount of solvent that can evaporate to fill the space in the bottle. Once the space is full of solvent gas, no more solvent evaporates from the glue and the glue stays runny.

∙ 12y agoBecause glue bottles where designed to hold the glue, not to have it stick to it. If it did stick to the glue bottle, we would not be able to get the glue out of the bottle.

How come Gorilla glue does not get stuck in its tube?
Because there is no water in the tube, water is necessary to start the hardening process.
How come Glue does not get stuck in its tube?
Because there is no air in the tube, but if you open one and re-cap it, you admit air and it will harden eventually.

In stores in my area, Super glue costs anywhere between 1.95 for a tiny tube (1.9ml) to around $8 for a large size (12.5 ml). It's also in the 'dollar' stores for 1 dollar a 1.8 tube, but I don't know the quality of that. I hope to test that soon.
