What is the synonym of glue?

Adhesive.


Why doesn't glue stick to the inside of its bottle?

Glue doesn't stick to the inside of its bottle because the inside surface of the bottle is typically made of materials that are resistant to the adhesive properties of the glue. Additionally, the design of the bottle's neck and opening are often smooth and non-porous, making it difficult for the glue to adhere.


Should two tubes that form a glue be a reactant?

No, the two tubes that form a glue typically act as a packaging and delivery system for the components of the glue, which then react once they are mixed together. The individual components of the glue inside the tubes are the actual reactants that form the adhesive bond.


What is inside of super glue?

Super glue typically contains cyanoacrylate, which is a fast-acting adhesive that bonds quickly to surfaces. It may also contain additives like stabilizers and thickening agents to improve its performance.


Why doesn't glue stick to inside of the glue bottle?

Another great and puzzling question. Why doesn't glue stick inside of the glue bottle. Glue on paper: As the glue connects with oxygen it becomes sticky and if left to dry in this oxygen it becomes hard and keeps multiple things together. Glue inside the bottle: Glue doesn't stick inside the bottle because the chemicals within the glue is triggered by oxygen (what we breathe) so when the glue bottle is opened it triggers the chemicals to make it sticky. That's why if a bottle if left out with no cap the glue becomes quite hard. Glue won't completely stick unless it's dried, and because inside the bottle, the glue is still air locked in and not dried, it doesn't stick.
