Epoxy resin is a high-strength and durable material used to create jewelry, as well as some furniture. It’s a very versatile and easy-to-use material, with many great applications.
Epoxy glue is also known as epoxy adhesive or just epoxy. Epoxy glues are used for filling in cracks and gaps, bonding materials together, and repairing small items like broken ceramics. They are the strongest type of glue commercially available.
Let’s take a closer look at what makes these materials so special, what they’re used for, the differences between them, and how they compare to other adhesives like super glue.
Will epoxy bond to resin?
So, will epoxy bond to resin? The answer is yes. However, there are a few things you need to know while making your decision.
First of all, it is important to understand that epoxy resin and epoxy glue are two different products. Epoxy resin is a two-part mixture that when combined forms a hard clear plastic.
Epoxy glue on the other hand is a strong adhesive that can be used for a variety of applications including plastic repairing.
If you want to use epoxy glue with resin then this is one option for bonding the two materials together. When using an epoxy adhesive to stick these materials together it’s important to make sure that both surfaces are clean from dust or any other particles before starting the project.
This can be done with rubbing alcohol or another type of cleaner such as acetone (nail polish remover).

Is epoxy glue the same as epoxy resin?
Epoxy glue is a general term for a range of products. But epoxy resin is a specific type of epoxy glue, which is commonly used in the industrial profession. This article focuses specifically on the differences and similarities between epoxy resin and glue.
Epoxy resins are thermosetting polymers that can be cured with the help of certain chemical reactions (epoxidation). Epoxy resin is widely used for bonding and sealing purposes.
What Super Glue is best for resin?
- Epoxy super glue has a lot in common with super glue. The two work the same way; they’re both made from a formula that’s activated by heat, or sometimes just exposure to moisture.
- Both adhere to different materials (plastics and resin/glass), as well as different surfaces (paper, wood, metal). Usually, epoxy is used for bonding metals to other metals. Super glue will sometimes be used with models made of plastic rather than resin/glass or wood because it adheres better to plastic than it does to glass.
- Super glue has several advantages over epoxy. For some people, one major advantage is the price of super glue is usually much cheaper than epoxy. Another advantage is that super glue dries faster it sets much faster than epoxy. If you prime your model properly before you apply the first layer of paint over top, it’ll only take a few minutes for the whole thing to dry. That makes this technique a good choice if you need your model finished within an hour or two of painting.
Can you glue epoxy to epoxy?
The short answer is no. Epoxy will not stick to epoxy. The good news is that epoxy bonds well to almost every other material, including concrete, metal, and glass.
The surface must be clean and free of oils, waxes, dirt, and mold release agents for the epoxy to bond properly.
If it has been 24 hours since you applied your first coat of epoxy and you have ensured that the surface is clean, then the second coat should adhere just fine.
What will epoxy resin bond to?
Epoxy resin will bond to most clean surfaces. But first, let’s look at what epoxy is not compatible with:
- oil, grease, or wax
- Teflon
- plastic that contains wax or oil (such as old bowling balls)
On the other hand, epoxy does adhere to most plastics and metals. This includes:
- wood (even treated wood!)
- fiberglass
- concrete
- glass
Aside from these materials, epoxy resin adheres to a wide range of substrates such as ceramics, stone, and fabric.
What will epoxy resin not stick to?
You might be wondering, Is there anything epoxy resin won’t stick to? Well yes! Epoxy will not stick to polyethylene or polypropylene plastic.
Both are commonly found in things like cutting boards and soda bottles (Note: It is possible to bond polyethylene and polypropylene surfaces with a special primer, but it’s not worth the effort for most small-scale projects).
Epoxy also does not stick to polytetrafluoroethylene (PTFE) or “Teflon.” This means that surfaces coated with Teflon, such as nonstick cookware, will resist epoxy resin. Lastly, epoxy resin does not adhere well to silicone.
How do you glue epoxy resin together?
Step 1. If you’re using two-part epoxy adhesive, mix the resin and hardener until they are thoroughly combined.
Step 2. With a small paintbrush or similar instrument, apply a small amount of the epoxy to one edge of your piece.
Step 3. Align this with the corresponding edge of your other piece, press it into place, and repeat steps 1-3 for each section you want to join together.
Step 4. Once all sections are attached using the epoxy, use C clamps or tape along the edges to keep them from slipping apart while the glue dries. Check your epoxy specifications for exact curing times you may need to wait several hours at room temperature depending on brand and type of epoxy used.
Once fully cured, feel free to remove any remaining clamps or tape as desired before proceeding with finishing touches on your completed project!
How long will epoxy resin last?
Epoxy resin has a shelf life of about two years, but it is best to use it within one year of purchase. This way you can benefit from the full range of its properties and adhesive strength. Check out the date of manufacture on your product or contact the manufacturer or retailer if you’re not sure whether you’ve got an expired product on your hands.
- Most products will only last for about 2-4 years, depending on how well they are stored. That means that if you do get some that have been around for a while, you don’t have to worry about it much.
Conclusion
Ideally, you can see the difference between epoxy resin, and epoxy glue by now. Epoxy glue is not a good choice for bonding resin, but that’s not to say there aren’t any suitable options.
Superglue is often suggested as an alternative to epoxy resin for smaller projects where you only need to bond two pieces together.
It’s not as strong or durable as epoxy resin so it’s best used on smaller items like jewelry or figurines and crafts where you don’t need something that will last a long time.
However, if you want to be sure your project will be safe using superglue then it’s worth doing some tests first before going ahead with your project.
There are lots of ways to bond two pieces of resin together depending on the type of glue and surface area involved in the bond.
