How come Super Glue does not get stuck in its tube?
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.
Why don't super glue go hard in the tube?
Any of these types of glue need air to dry. If the tube is kept tightly capped it can't dry.
