Superglue was originally discovered by America Scientists in 1942 when they needed to make transparent gun sights during the WWII. Superglue is basically the adhesive that you would probably turn to if you needed to really stick together anything in a flash – superglue bonds in seconds.

And truly, if you haven’t had a bit of a mess up with superglue on your hands and that awkward moment when you superglue two fingers, then you may have not just started truly living on this earth.

Is Superglue waterproof?

So, a lot of people usually pose this question, Is superglue waterproof? Firstly, the word super glue pertains to all the different types of cyanoacrylate (CA) adhesives. And usually, there are different kinds of this CA adhesives intended for specific applications. Super glue is able to make two materials bond quickly due to its rapid polymerization in the presence of water – which is usually the humidity that is present in the air.

Our regular super glues, are they actually waterproof? Can they take a swim in water and come out unscathed?

Actually, super glues are not waterproof, at best they can be said to be water-resistant and will survive the occasional splash or brief soak in water and still retain its bonding properties. This is chiefly due to the fact that, the bond joint in a super glue will weaken and break apart if it is constantly immersed or dipped in water.


On the other hand, this does not spell doom for you if you need to glue something that will be immersed in water, as I mentioned earlier, there are different kinds of Cyanoacrylate adhesives (the material for making super glue) and they are all intended for different applications and specific purposes.

Thus, there are Waterproof super glue purposes that were specifically made to do well in water and the bond is unaffected by water, so they can be used to bond materials that would be submerged in water. Waterproof superglues are made with special glue formulas that ensure that they remain unaffected by water or moisture in general – even if they are submerged in it.
Therefore, you need to ensure that you have the right kind of glue for a specific purpose.

If you would need to bond two materials together that does not come in contact with water, then you can use the regular glue. However, if you need to join two materials that will be submerged or immersed in water, then you should opt for waterproof superglue products.
