why the super glue is highly sticky? |
The major constituent of Superglue is a chemical called cyanoacrylate.Superglue needs to form these strong bonds in hydroxyl ions found in water. This makes applying superglue easy as almost all surfaces contain traces or a thin layer of water. As Superglue comes in contact with water it forms long, strong chains, which bind the two surfaces together almost immediately. Superglue forms an almost unbreakable, waterproof bond within seconds. |
