Is super glue or epoxy stronger?

Welcome to our introduction to super glue vs epoxy. We’re going to explore the differences and similarities between them, what they are used for and when you should use them.

Superglue is a type of adhesive that comes in liquid or gel form. It is made from cyanoacrylate, a synthetic chemical compound.

It was discovered by accident by Dr Harry Coover Jr when he was working for Kodak on finding clear plastic gun sights for the US military during World War II in 1942.

Epoxy is also an adhesive like super glue but it comes in two parts. One part is made from resin and the other part from hardener.

When put together these two parts create a strong bond which makes epoxy one of the strongest glues around.

What’s the difference between epoxy and super glue?

Choosing between epoxy vs super glue can be a tricky decision. If you have been using super glue your entire life, it may seem natural to reach for it when you need to repair something.

However, in many situations epoxy may work better. Epoxies are actually a type of adhesive, but they are different from one-part glues like cyanoacrylates and polyurethanes.

Let’s take a moment to understand the difference between these two types of adhesives so that we can make an educated decision before beginning our next project.

Is epoxy or super glue better for plastic?

If you are gluing plastic, then epoxy is clearly the best adhesive for the job. Yes, super glue may work on some plastics in certain instances, but if you want to create the most secure bond possible then epoxy is your best choice.

This is because when it comes to plastic adhesion, epoxy creates an almost unbreakable seal while super glue has a tendency to weaken over time.

However, if you have a wooden project that needs building or repairing then super glue will be your most useful go-to adhesive.

While epoxy can also be used on wood projects and repairs, super glue is often better because it dries faster and works well with a wider variety of woods. Super glue can also be used effectively on metal surfaces such as stainless steel or aluminum.

Epoxy can also be used on metal surfaces but it creates a more temporary hold which can loosen over time due to exposure to heat or moisture.

Similarly, neither adhesive works particularly well with porous materials like concrete so if you plan to work with this kind of material then it’s better to use a different bonding agent altogether.

What types of glue are the strongest?

There are different types of glue, and each one has its own unique strengths. For example, super glue is stronger than epoxy. Epoxy is stronger than gorilla glue. And gorilla glue is stronger than wood glue.

Is 2 part epoxy stronger than Gorilla Glue?

No, Gorilla Glue is not stronger than epoxy. In fact, there are a lot of differences between these two products besides strength. Here’s how to decide which one is better for your project.

First, let’s take a look at the pros and cons of Gorilla Glue:

  • It dries slowly, allowing any mistakes to be fixed quickly
  • It can be applied to many different surfaces – wood, stone, metal, ceramic
  • Its adhesive strength is weaker than epoxy’s
  • It does not need a hardener or catalyst in order to cure
  • The cure time is dependent on the amount of moisture in the air

Now let’s compare Gorilla Glue with its cousin product, 2-part epoxy glue:

  • Epoxy glue has an extremely strong initial tack (the stickiness when you first apply it) and also long-lasting adhesive power.
  • Unlike Gorilla Glue, it needs a hardener or catalyst in order to cure. This means that once you mix the parts together they have a certain time limit before they become unusable.
  • Epoxy glue will bond almost anything except rubber and plastic. If used on these materials instead of Gorilla Glue they will dissolve into each other.

What happens when you mix epoxy and super glue?

As you can see from the above breakdown, the combination is not very strong and should not be used for any kind of structural support. However, in some cases, a more flexible bond may be desired.

The mixture does create a very good sealant as it is flexible and water-resistant. Although it is not waterproof, it does work well as an adhesive for woodwork or other applications where the parts being joined are subject to moisture or high humidity.

The mixture is non-toxic and should be safe for use around children. It is also non-flammable making it an ideal glue for many household projects around the home or workshop.

Since epoxies and super glues are both two-part adhesives that must cure before they are fully effective, their combined strength will vary depending on how long they have been curing when you test them.

The longer they cure together, the stronger they will be (although never quite as strong as using one or the other alone).

Can I use super glue on top of epoxy?

Epoxy is much stronger than super glue.

Epoxy is also much more durable than super glue and will last you longer. Epoxy has a high resistance to water, which makes it perfect for outdoor use and underwater use.

Super Glue is not waterproof or water-resistant, so using super glue outdoors or underwater is not recommended.

Which is stronger Gorilla Glue or Super Glue?

Super Glue vs. Gorilla Glue: Which is stronger?

Well, it all depends on the type of glue and the kind of bonding you need to do.

Super glues are mainly cyanoacrylates, which are fast-acting adhesives that form a strong bond between materials. However, superglues (like Gorilla Super Glue) have a very low tensile strength because they are not designed to keep things together under pressure.

This makes them ideal for materials that need to be held in place, but not subjected to stress. So if you’re using super glue to reattach your fingernail after an accident at work, you can expect it to stay where you put it but don’t expect that nail to withstand any heavy lifting!

On the other hand, Gorilla (Polyurethane) glue is made from a different chemical compound and is much stronger than super glue. It has a greater tensile strength meaning it can be used to secure items that will be subjected to stress or strain over time—so this type of glue is ideal for projects like repairing broken furniture legs or holding together cracked porcelain figurines.

How strong is super glue?

The strength of super glue also depends on the type of super glue. The most common type of super glue, and the strongest one, is cyanoacrylate.

Knowing this can help you choose which to use for your project, as it’s important to know how strong a bond you need between two surfaces.

Sometimes, epoxy is stronger in some applications than super glue. In fact, the strongest adhesives are epoxies.[8] They form very strong bonds with both plastic and metal surfaces and can withstand high temperatures and other extreme conditions once they’ve cured.[9]


Epoxy can be much more useful than regular super glue. Use epoxy when you are dealing with water, using materials that expand or contract, or working with a large surface area.

Super glue is great for small repairs and everyday use. The biggest advantage of super glue is that it is fast and easy to use, making it perfect for small projects and quick fixes.

If you’re working on a large project that needs an extremely strong adhesive, epoxy can be used as the base layer before applying super glue on top. Using the two adhesives together results in a stronger bond than either one alone.
