How does super glue work?

Have you ever been on the brink of a DIY project, only to find out that fixing something requires more than just duct tape? That’s when super glue comes in handy.

But what is superglue and how does it work? Let’s take a look at this magical adhesive.

The Science Behind Super Glue

Super glue, also known as cyanoacrylate, is an adhesive that works by forming strong chemical bonds between materials. When two surfaces covered with super glue come into contact with each other, a reaction occurs that causes the molecules in the glue to break down into small pieces and form a rigid plastic bond between them.

The glue rapidly polymerizes, or hardens, when it comes into contact with the water molecules on the surface. This forms a strong bond between the two surfaces being joined. Superglue can be used to bond a wide variety of materials including metal, plastic, wood, and ceramics.

However, it is not recommended for use on flexible materials or for applications where the bond will be subject to stress or movement, as the bond may fail.

The process happens very quickly, usually within seconds of contact. This fast-acting quality makes super glue an ideal choice for quick fixes and repairs.

What Makes Super Glue So Sticky?

One of the reasons why super glue is so effective is because of its molecular structure. Cyanoacrylate adhesive contains molecules that are made up of three atoms; carbon, nitrogen and oxygen. Which are arranged in such a way that they fit together tightly. This tight bond makes it difficult for any other molecules to get between them, which gives the glue its remarkable strength and stickiness.

Another thing that makes super glue so effective is its ability to form tight bonds with porous surfaces. Unlike other types of adhesives, cyanoacrylate can bond with surfaces like wood or fabric without leaving gaps or air bubbles between them, which helps create a strong seal between two objects.
