Super Glue and epoxy are two types of adhesives that are commonly used around the house or in industrial settings. These powerful glues are often chosen for their strength in DIY projects, as they offer a superior bond and versatile functions. But what is the difference when looking at Super Glue vs epoxy? And Which adhesive is best for which projects? Let’s take a deeper look into these two adhesives.

Super Glue vs Epoxy – What’s the Difference?
Both adhesives produce a pretty fast drying and powerful bond between a wide range of surfaces. So what is the difference between Super Glue and epoxy? Ultimately, the difference comes down to the way each glue cures.
Super Glue is a single component adhesive – meaning that it only comes as one substance. This is made from a substance called cyanoacrylate which hardens when it is exposed to the air. Epoxy glue is different in that it consists of two separate components that require mixing together. The first part is epoxy, and the other is a substance called hardener. When the two mix together, a reaction takes place which causes the epoxy to dry. This means that you only have a limited time to work with the adhesive before it hardens.
While both adhesives form a long-lasting and strong bond, there are some differences in how each one can be used. When comparing Super Glue vs Epoxy, both have a unique set of characteristics.
Properties of Epoxy vs Super Glue
Although both epoxy and Super Glue produce a strong bond, there is a difference in the type of strength that each one holds.
An epoxy adhesive has serious structural strength. This makes it a good choice for bonding gaps between two parts. Epoxy can hold a strong bond when there is resistance from any angle. When asking how strong is epoxy, you will need to understand the specific type of strength. Epoxy is often used in a variety of industrial settings. Epoxy is also often available in a putty form. This means that it can work as a filler as well as an adhesive – making it suitable for gaps, holes, and cracks. Once cured, epoxy can be sanded down to a smooth finish and coated.
Super Glue has a lower shear strength. Basically, this means that if you try to directly pull apart the two parts bonded, Super Glue will resist this. The glue will not be able to handle off-angle stress though. This makes it a good solution for fixing smaller items, and particularly things that dont move or support a load. As Super Glue dries to a clear finish, it is a good choice for various arts and crafts projects.
Super Glue vs Epoxy – Top Products
The best way to really understand the difference between these two adhesives is by comparing the two products next to each other. If you are looking for great quality glue, then these are two of the best options in each category.
Best Epoxy: GORILLA 2-Part Epoxy
When it comes to epoxy adhesives, Gorilla is the brand to choose from. This two-part epoxy glue offers a permanent, gap-filling solution for multiple surfaces. The provides an extremely durable bond for tough repairs and is completely solvent resistant.
The adhesive is packaged into an easy to use double-barrel syringe which makes mixing the components precise and convenient. This adhesive is quick-drying, dries completely clear, and is suitable for indoor and outdoor use.
Best Super Glue: LOCTITE Ultra Gel Control Super Glue
This instant adhesive is a fantastic choice for quick fixes on a wide range of surfaces. The glue is rubber-toughened and can resist shocks, impact, vibration, and extreme temperature. This glue works on metal, ceramics, rubber, plastics, leather, wood, and paper.
This Super Glue dries instantly so it doesn’t need any clamping. The finish is clear for all kinds of surfaces. This bottle is particularly clever, as it has a special side squeeze design. This makes it easier and more precise to control.
Using Super Glue Epoxy
When comparing super glue vs epoxy, you really need to consider how each substance is used. Epoxy has a wide range of forms and uses. It can be applied as a coating for various surfaces, molded to form models and crafts, used as an insulator for electronics, and it can even make floors.
As an adhesive, epoxy can work on a wide range of surfaces. Just be sure to check the specific manufacturer’s guidelines, as certain products may not work on some surfaces. Generally, an epoxy adhesive is used to bond items that are under greater force.
Super Glue does not have as many uses and is used in smaller doses. The basic epoxy vs glue comparison is that Super Glue is used more in crafting, doing quick fixes around the house, and joining together small parts. The finish of epoxy vs super glue is also an important consideration. Epoxy can dry to various finishes, from a clear glue-like finish to a thick putty. Super Glue dries thinner and completely clear. This makes Super Glue more suitable for finer details and items that require a perfect finish.
There is also quite a difference in working with and cleaning up, epoxy vs glue. When the epoxy has hardened, it is near impossible to remove. If you do remove it, it will likely damage the underlying surface. When the epoxy is still in a liquid form, it can be cleaned up with vinegar or acetone.
Super Glue is easier to clean up, which can be done once it is cured or still wet. You can simply wipe the glue away using acetone or gamma-butyrolactone. Super Glue also dries much faster and is more efficient to work with.
Frequently Asked Questions
How Strong Is Epoxy Adhesive?
Out of all the reactive adhesives out there, epoxy is considered the strongest. This is resistant to high temperature, UV light, solvents, and impact. Typically, epoxy can hold about 300 lbs of tensile strength.
Super Glue vs Epoxy, Which Is Better?
Both form a very powerful bond and are good for specific uses. The type you choose should depend on your project. Super Glue has less shear strength but is easier to use. Epoxy has better structural strength.
How Long Does Epoxy Glue Last?
This depends on the specific product and conditions. If epoxy glue is properly applied to a surface, it can last seemingly forever. This material forms an incredibly powerful bond.
The Super Glue epoxy debate should depend on the type of project the adhesive will be sticking together. Both options offer an excellent choice in their specific areas. If you are comparing epoxy vs Super Glue, there is no better and worse option. Both are powerful adhesives with their particular strengths.
