Epoxy VS Super Glue-Which One is Best?

Epoxy VS Super Glue

Recently, I walked into a crafts store and couldn’t believe my eyes. There were plenty of glues on display, all coming from the best brands you can think of in this era.

Confused on which one to pick, I had to ask help from the storeman. While he did not give me a specific glue, he advised that i should pick glues under the brand Epoxy or Superglue.

According to him, these two types of brands produced the best glues in the industry. However, he could not point a finger on the one that outdoes the other.

As a result, I bought two glues each belonging to either of the brands and, used them on different occasions on my crafts. Plainly, the two types of glue, just like the storeman advised, are very effective on projects.

However, they are not entirely the same because of various factors.

To familiarize you with what I am saying and help you settle for what will work best for your project, here is an article independently explaining each of the glue before coming up with their detailed comparison. So let us get started with the Epoxy glue.

Epoxy  Glue

Epoxy is not like any ordinary glue out there. What do I mean? Well, most glue comprise a one system structure. However, the Epoxy glue, since it comprises the polyepoxide chemical compound, is a two-part system glue.

That means that it works through the use of resins as well as hardeners for effective results.

With this brief information, let us get into a deeper and perhaps easier understanding of the Epoxy glue by checking out some of its key features listed and explained as follows:

Adhesion power

One of the reasons why I was given the Epoxy glue is because of its strong bonding capabilities, and the glue did not disappoint in this aspect.

Primarily, Epoxy is the one glue that you use on your projects, and you do not have to worry about them coming off any time soon.

This is because of its two-part system where the resins and hardener, when mixed together, form an even stronger bond.

The higher the ratio mixture, the stronger the bond of your crafts.

The only problem is that mixing up the substances to come up with an excellent ratio is normally challenging for the novice and the newbies. You have to be a professional or seek help from a qualified person.

Excellent Formula

We all know that glues tend to behave awkwardly under certain conditions. Take the case of water, for instance. Most adhesives, while they get into contact with water, they gradually lose their strength.

Fortunately, the Epoxy is not one of these glues because of its waterproof formula.

That means that if you intentionally or unintentionally spill water on your Epoxy glues project, the craft will not get damaged. In fact, I tried hardening a piece underwater, and the glue worked out perfectly!


One of the reasons why Epoxy qualifies as a professional glue is because of the mixing aspect.

However, this is not the only reason why the glue fits as a professional glue. The other reason is because of its compatibility with various materials.

The glue is not only limited to handling a specific type of material.

You can use it on almost all materials, from wood to metal to glass and even plastic. What’s more, it is not only suitable for small and DIY projects. It is also ideal for large and complex crafts.

Super Glue

The other glue we are tackling in this article is the  Super glue, which is very popular among most people.

While we can go on and go describing this glue, let us get do that in the least way possible.

Super glue is a one-part system glue belonging to the cyanoacrylate compound family. As a result, it does not react by mixing resins and gardeners. Instead, it works exothermically.

That means that once placed on the respective material, it reacts with its surface to produce heat, which is responsible for the bond that transpires. Here are some of its key features.

Bonding power

One of the major things that we consider before buying glue is its bonding ability. Nobody wants a glue that will not stick to their material projects.

Luckily, Super glue had this factor while manufacturing their adhesives. This is because the bonding power of this glue is often reasonable.

This does not mean that it is weak, and it also does not mean that it is super strong.

It means that the strong ability of this glue is slightly strong and will work excellently on preferred materials. However, you have to be cautious of the time limit of the bond as it tends to loosen up as time goes by, but not soon.

Fast drying

Now, if you are looking to fix something really quickly, then Super glue is all you need.

After trying it out on a number of crafts, I can confidently affirm that this adhesive has a high drying capability. It will literally take a couple of minutes to set and about a day or less to completely cure.

Therefore, you do not have to worry about your projects getting in the correct shape on time once you have used Super glue and have followed all the guidelines as provided on the bottle or by the manufacturers of the brand.


Just like the Epoxy glue, the Super glue is also versatile. However, it’s versatility is quite unique. Remember, I said that the bond of the super glue is not as strong and may come out after some period, right?

This means that super glue is only versatile for small and DIY projects, especially those within the household. Moreover, the glue cannot work on a variety of materials.

It works on a limited number of materials, especially wood material.

Epoxy VS Super Glue

If you religiously went through the above section, then you can already point out a number of differences between the Super glue and Epoxy glue.

However, if you only focused on the point, you must be wondering if there is any difference between the two types of glues.

Whichever way you read the previous section, here is a chance to better understand the distinction between Epoxy and Super glue.

Yes, in this section, we get a little personal on Epoxy vs. Super glue by listing five of their differentiating factors and how they differ in each of the listed factors.

Components and structure

Super glue and Epoxy glue are not from the same compound family. The Super glue categorizes under the cyanoacrylate compound family.

On the other hand, the Epoxy glue classifies under the polyepoxide compound family.

What’s more, the two have different glue structures. Primarily, the Epoxy glue is a two structured type of glue.

This is because it’s functionality depends on the use of the resins and the hardener. However, the case is not similar for the super glue as it has a normal glue structure that does not require the use of mixtures.

It is this difference in components and structure between the Super glue and Epoxy glue that leads to the existence of all the other differences below.

Bonding power

Directly linked to the first difference is the bonding power. Ideally, this refers to the strength that each glue has in terms of sticking materials together.

This is seen in the time the glues take to loosen and in the type of projects they can handle. Yes, both the Epoxy and the Super glue have very strong adhesion.

However, while compared against each other, then the Epoxy appears much superior to the Super Glue. Championing this statement are two factors.

Firstly, it is very rare for the Epoxy glue to loosen up once it is clamped and well dried. Unfortunately, there have been incidences of the super glue coming off after a certain period of time.

Secondly, Epoxy can be applied in all forms of projects beginning with the household ones down to the complex and professional crafts.

On the other hand, super glue cannot work well on such projects. It only works on small household crafts due to its strength capability. However, on these specific projects, it does the work excellently.


Both the Epoxy and Super glue are versatile. However, the degree of their versatility differs in terms of scale. While the Epoxy operates on a large scale, the Super glue is limited to small scale operation.

What this means is that the Epoxy glue can work in a wide variety of projects, including the minor to the complex ones.

Also, it is not very selective on the materials as it operates exceptionally in most materials. The Super glue, however, operates on limited materials and can only handle the minor projects.


I know you are wondering why the mechanism is listed here, yet most of you know that with glues, you only need to apply it on the surfaces and clump. Well, this is not the case for the Epoxy.

Since it has a dual structure, it works through mixing resins and the hardener, and this is what gives the glues it’s extraordinary strength.

Unlike the Epoxy, super glue normally works through exothermic reactions where the bonding power is generated once the glue meets the respective surfaces. That next difference between Epoxy and Super glue relates to ease of application.

Ease of use

Sincerely speaking, you will have a rough time using the Epoxy glue, especially if you are a beginner or a novice.

This is because unlike the super glue where you just open and apply on your materials, you have to apply some procedure when using the Epoxy.

Here, you will need to come up with the correct ratios of the resins and the hardener before you begin the application.

This is usually not an easy task unless if you are a professional. Therefore you want to undergo some classes or seek help before you can use the Epoxy glue.

Water resistance

Based on the review of the Epoxy glue, it is apparent that the glue is highly resistant to water. That means that you can use the glue in a watery area or in an area exposed to solvents, and it will not interfere with your crafts.

However, you can not try the same while working with the super glue.

This is because there is no mention of whether it is water-resistant or not, which only means that there is a possibility that the glue is not waterproof. Thus, you have to be very careful while using it around solvents.

Clean up

Whether a professional glue user or not, you are still human. That means you are prone to making mistakes while using your glue. If this occurs, you want to clean up the mess right quickly.

 Well, the same cleanup method for super glue is not the same as that for the Epoxy glue. Primarily, you will need acetone or vinegar to clean up any messes caused by Epoxy.

However, stay warned that the process will be even harder once the glue sticks. With regard to super glue, you can clean it up using acetone nail polish remover or gammabutyrolactone (GBL).


Both the Epoxy and Super glue are excellent glues. All you have to know is the materials and type of project you are using.

For the complex and professional projects, you are advised to go for the Epoxy glue. While handling simple projects, it is recommended to settle for the super glue.

This way, you will not worry about quality service. However, you have to keep in mind that both of these glues are very toxic and dangerous to human health.

As a precaution, you hence have to use these glues in a well-ventilated area and even put on some gloves to avoid any damages on your skin.

6 thoughts on “Epoxy VS Super Glue-Which One is Best?”

  1. I have used both in hobby crafts.
    CA glue is good for small non, weight effected parts (tiny display).
    I have notice though the parts will come apart. Keep a bottle handy.
    Epoxy, is more durable. Its never failed on parts handled frequently..
    Epoxy is harder to use, you need to mix small amounts, for small objects and dry time is longer. This makes for longer build and assembly times.
    I found out shelf life for unused epoxy is not long . the resin glue breaks down. and loses bonding power if left stored (softer).
    I prefer epoxy for bonding and long endurance (nothing has fallen apart after decades). Super glue (CA) has its place. fast good bond for immediate use. (but not as durable).
