​​Why doesn’t Glue Stick to its container?

That strong smell that comes out when we open the tube’s cap is due to the solvents evaporation, so once they’re gone the glue sticks. If a superglue tube is left open for a long time (exposed to air, allowing the water to come in contact with the glue), it’s impossible (or almost) to squeeze it out and therefore sticks to the container. You may have noticed that super glue tends to dry out in its container more quickly than white glue. Super glue works differently than white glue. Instead of the polymers in white glue, super glue is made of a chemical called cyanoacrylate. This chemical bonds things together when it reacts with water vapor in the air.
