The Epoxy VS Super Glue Battle – Which One Wins?

​When something breaks at home, work, or school, we need the right tools for the job in order to fix it properly. The epoxy vs super glue debate has been raging for years. But ​how do you know which one to choose for your situation?

The use of adhesives is universal. Whether it’s for manufacturing heavy-duty objects or for fixing fine china at home, glue is almost a human necessity. And as users, we will always want the strongest, best glue ​we can get our hands-on.

However, along with the strength of the glue, we also need to consider the ease and ​convenience of ​it as well. This is especially true for common household work and other common repairs. Consumers want safe, easy-to-use glue for a very quick fix.

In this article, we’ll discuss the properties of two of the strongest glues out there, Epoxy and Super Glue. Many people actually swear by either of these, although professionals are probably more likely to use Epoxy​ than your mom would when she’s fixing her favorite vase.

Now, let’s consider the deciding factors of these two types of glue.

Epoxy Glue

Epoxy glue is actually a chemical compound called polyepoxide. For use, epoxy resins and hardeners must be mixed together in fixed ratios. The resin is an adhesive gel-like substance, that when mixed with the hardener, creates a very strong glue.

When should I use Epoxy?

Comparatively, Epoxy glue is much stronger. And strength is obviously a very, probably the most, important aspect to consider when buying glue.

The ratio of the hardener mixed with the epoxy resin determines how strong the glue will be. But using more hardener while making the adhesive stronger makes the dry process last long. At the end of the day though, you are getting glue that will last you a very long time.

The epoxy is also completely waterproof. As a matter of fact, this amazing glue can even harden underwater! Which is perfect for the manufacture and repair of so many useful objects.

It is also worth noting that epoxy glue is very tough to remove. Normally it is used to hold something permanently and it delivers! Thus, epoxy is used abundantly in industrial works and for fixing heavy-duty objects. Honestly, can you blame the users? This adhesive is seriously impressive.

​What are the Downsides of Epoxy?

And now for the cons! Epoxy glue, for one, is really only suitable for professional users, or at least people who are accustomed to using it a lot.

Mixing and getting the ratios right requires an understanding, or at least some guidance. That is why epoxy glue is specifically made for industrial use. Also, the large amount of time taken for the glue to set may not be ideal for everyone.

Super Glue

Super glue is actually a brand of glue, which is a form of the cyanoacrylate compound. This is found in tubes and is normally a watery liquid that works using exothermic reactions. Meaning, the glue reacts to the material put on and releases heat, which helps stick the objects together.

​When Should I use Super Glue?

Super Glue, on the other hand, is perfect for household use. It does not require any complicated mixing of ingredients. Determining which ratio works best is obviously tough and without professional knowledge, the work cannot be accomplished right.

At an emergency, you can pop the tube out, and just stick the broken objects together. The glue dries very quickly which adds to the comfort of its use.

​What are the Downsides of Super Glue?

On the other hand, Super Glue does not retain the strength and reliability that epoxy does. It can be dissolved easily and over long periods of time, can lose its strength.

To have an object once fixed come lose again, is definitely not preferable. Also, the exothermic reaction created by the super glue may be dangerous for the user. The release of heat could cause serious burns, and really, no one wants to risk that!

The fact that super glue is very runny and liquid is a hazard as well. A lot of the time, the glue drips down onto the user’s hands and causes skin damage. Also, the glue is not water-resistant at all, which, compared to the epoxy is quite an unimpressive trait.


1. Can Super Glue be used for industrial purposes?

No. It is really not a strong enough glue to hold heavy-duty objects. For this, Epoxy is your best bet.

2. What do I do when I get super glue on my skin?

This may be dangerous, so act quickly. Run cold water over the affected part and use a towel or your hand to rub the glue away. This will take a little time but once the glue starts to harden and cool, it will come off in flakes easily.

3. How long can I store glue?

Epoxy glue will last for around two years when kept in cool conditions. Super Glue won’t last too long but for an extended shelf life, keep the tube sealed, so no air enters.

​Final Thoughts on the Epoxy vs Super Glue Debate

At the end of the day, the decision is completely up to you. Whether you prefer to sacrifice the extremely reliable strength for better ease of use, it’s your call.

Or, if water resistance is an important aspect to your work, maybe a little mixing and testing won’t seem like ​much of a hassle. Plus, even though the strength of an adhesive is very important, you don’t want to get something that could potentially harm you.

This article has only pointed out the many differences and uses of the two types of glue. Hopefully, ​this information will guide you ​when you’re buying the right adhesive for your next job.
