Can I use epoxy as glue? – Epoxy is one of the most common types of adhesives and is used in various industries such as construction, manufacturing, and aerospace.
The incredible strength of epoxy comes from its chemical makeup that gives the adhesive a glue-like consistency.
Can epoxy be used as glue?
Epoxy is a type of adhesive that is made up of two parts: a resin and a hardener.
It works by chemically bonding the two components together through a chemical reaction, creating a hard, plastic-like material.
Because of this chemical reaction, epoxy can be used as an adhesive. Epoxy’s strength and durability make it one of the strongest types of glue available for household use.

Is epoxy glue the strongest?
Epoxy is also very strong. It’s stronger than normal glue, stronger than Gorilla Glue®, stronger than wood glue, and even stronger than Super Glue®.
You can use it to adhere to surfaces like wood, plastic, metal (including aluminum!), glass, and even concrete!
Is epoxy resin same as glue?
E-resins (or epoxy resins) and epoxy glues are two very similar materials that are often confused with one another.
They both have the same chemical formula, but their performance characteristics are different:
E-Resins
- Epoxy resins are used for general purpose adhesives and sealants.
- They’re great for making temporary repairs and bonding broken surfaces.
- This material is also great for fixing small holes where paint has peeled off.
- It’s also good for nailing wood to wood when you can’t use nails because of moisture.
Should I use epoxy or glue?
You may be asking yourself “is epoxy glue or super glue stronger?” You would be correct if you think of them as being the same.
Epoxy and super glue are both very strong adhesives, but their strength comes from different sources.
Super glues are cyanoacrylate based. They form a bond by chemically reacting with the moisture in the air between the two surfaces being joined together.
That is why they do not work well on underwater applications. Epoxies form a bond by chemically reacting with each other over time to form a solid plastic (like what happens when you mix two-part epoxy resin).
Epoxy is more expensive than superglue but it produces a much stronger bond than superglue and works on more materials than just plastic.
In most situations where you would use epoxy, it will produce a stronger bond than any other adhesive available at your local hardware store including wood glue and Gorilla Glue.
Is epoxy stronger than superglue?
Epoxy is a great adhesive. But it’s not always the best adhesive for every situation.
For example, if you’re fixing something that may experience a lot of stress or strain (like a broken coffee mug handle or the heel of your favorite shoes), maybe you should use superglue and some wood glue instead.
Epoxy is also much more expensive than superglue, so you don’t want to waste it on things that won’t take advantage of its durability.
The average tube of epoxy costs $5 while the average bottle of superglue costs $2-3. Also, epoxies are harder to work with because they need to be mixed together in equal parts before application and have a shorter curing time than other adhesives like silicone.
Is epoxy stronger than wood glue?
Yes, epoxy is stronger than wood glue. It’s quite a bit more expensive, too.
If you are building a joint that will not be subjected to shear forces and where appearance is paramount, I would use wood glue if strength is the only consideration, epoxy rules.
Epoxy has higher tensile strength and shear strength than wood glue.
However, in one study of glues used in cedar fence construction, epoxy was found to be weaker at holding the pieces together than other types of adhesive when tested on cedar alone.
It may have been that the moisture content of the tested boards affected the results.[1]
Is epoxy stronger than Gorilla Glue?
It is stronger than Gorilla Glue and stronger than wood glue. It’s also stronger than superglue, which can successfully join together many types of materials but typically is not as strong as epoxy in terms of sheer adhesive strength.
Epoxy can be used in place of glue, although it’s better to think of it as a “glue plus” option that combines the properties of polymer adhesives, sealants, and reinforcing fillers.
Is epoxy glue the same as super glue?
Epoxy is not the same as super glue. Epoxy is a resin, while super glue (cyanoacrylate) is an adhesive.
Epoxy is a thermoset plastic, while super glue is a thermoplastic. Super glues are cyanoacrylates, and epoxies are epoxies.
Epoxies are thermoset polymers that irreversibly cure and become hard plastic when mixed with their curing agent or “hardener” (typically an amine).
Super glues contain tiny molecules that bond very rapidly with the surfaces they contact, forming strong chemical bonds that can be difficult to break apart later.
They require little or no surface preparation prior to use and have concise working times but long setting times (usually 5 minutes).
Epoxies contain large molecules that bond very slowly, if at all without mixing a curing agent or base with its hardener.
This process creates heat and chemically turns the epoxy into a solid polymer (plastic) bond once it cures, which usually takes several hours at room temperature depending on brand and mixture ratio of ingredients (resin to hardener).
Conclusion
Now that we have discussed the difference between epoxy and glue, we can say that, even though both are used to join two surfaces together, they each do so in a different manner.
Epoxy is like a super-strong liquid plastic that you mix. When it hardens, it will be as strong (or even stronger) than the material it’s being used on.
It really depends on what type of epoxy you’re using and what materials you’re joining.
Glue is not as strong and it acts more like an adhesive than a material.
Glue does not bond or join materials together as much as it simply sticks them together.
Glues act like an additional layer between two surfaces rather than creating one surface from two separate ones.
