You may have heard of epoxy and resin, but you might not be sure what the difference is. They are both used for many applications like coatings, casting, jewelry making, and other craft projects.
Epoxy tends to be the go-to choice for many people because it’s easy to use and it comes in a wide array of different formulations.
The term “epoxy” can refer to any two-part plastic adhesive or coating that includes an epoxide group in its chemical makeup.
You can also think of epoxy as short for epoxide which is a particular type of oxygen molecule found in compounds like polymers and cyclic ethers.
Meanwhile, resin is a much more specific term that has multiple meanings depending on the industry it’s used in. Resin can simply refer to any liquid compound that hardens over time or at room temperature; one example would be tar paper in roofing materials.
Resin can also refer to materials that are extracted from living trees during sap extraction processes; this process is called tapping. In addition, resin can also refer to hydrocarbon compounds such as crude oil or petroleum products.
Is epoxy the same as epoxy resin?
Great question. Essentially, “epoxy” is the name for a system that consists of two parts: resin (Part A) and a hardener or curing agent (Part B).
Epoxy resins are thermosetting polymers that have exceptional strength, toughness and chemical resistance.

Are all epoxy resins the same?
Is there a difference between epoxy and epoxy resin? Yes, it’s important to know the difference so that you are using the appropriate product for your project. So let’s go over some basics.
The word “resin” is often used interchangeably with the word “epoxy,” but in reality, they are very different products. Epoxy itself is a general term used to describe a type of plastic material made from monomers and oligomers that have been reacted together to form long molecular chains that cure into a solid form.
In other words, epoxies are polymers: they contain many repeating units of smaller molecules called monomers or oligomers that bond together during a curing process (which can be heat- or chemical-activated).
Epoxies can come in several different forms: liquid, powder, or film (or any combination thereof). When two components are mixed together in equal amounts (a resin and hardener), this mixture is referred to as an epoxy system.
The resulting cured material is called an epoxy resin. Put simply, epoxy resin is a type of reactive plastic polymer containing epoxide groups.
Which is stronger resin or epoxy?
Epoxy and resin are both strong, versatile materials. However, epoxy is considered to be the stronger material of the two. It is more effective at bonding surfaces than resin. Epoxy is also more heat-resistant than resin and not as flammable.
What can I use instead of epoxy resin?
Here are a few things you can use instead of epoxy resin:
- Polymer clay – You can find this at stores like Hobby Lobby and Amazon, as well as some specialty craft stores.
- Hot glue – This is available at Home Depot, Lowe’s, and online. If you’re using hot glue to make your own sculptures, remember that it won’t actually dry all the way through—so if you want to be able to move it around a bit without accidentally breaking it, this might not be right for you!
- Butter – You probably have butter in your fridge right now! It works well with bread or pancakes too. Keep in mind that this option might get messy though…
- Water – Many people use water instead of resin when they make sculptures because it’s easier on the environment and cheaper than buying new epoxy or regular plastic epoxy.
Is epoxy resin expensive?
- Epoxy is a substance that can be used in different ways. When it comes to epoxy resin, there are many questions about product costs. It’s important to know what you’re buying and how much it should cost.
- Is epoxy resin expensive? The answer depends on the type of project you choose for your epoxy resin solution. You need to know what you need to buy before you can determine if the product cost is reasonable or not.
- The main difference between epoxy and epoxy resin (and why they are often thought of as the same material) is that one isn’t technically a material, while the other is a general term for strong adhesives used in many different fields/industries; however, they do share some similarities, including being thermosetting polymers with thermoset properties (such as curing at room temperature).
- Epoxies are generally less expensive than their counterparts due to having low viscosity levels (which means they flow slowly) along with higher heat tolerances when cured correctly – this allows them more flexibility in application methods such as potting compounds or casting resins where additional costs might otherwise be incurred by using other materials like polyester resins which require higher temperatures during processing (especially for small batches).
Which epoxy is best?
If you’re new to the game, it’s easy to feel like a fish out of water. All these different types of epoxy, what are they for? The short answer is that each type has a different composition and application. Here’s a breakdown:
- Epoxy resin: Epoxy resin (sometimes called casting resin) is usually used for coating applications as it cures to a very strong and hard finish.
- Fiberglass resin: Fiberglass resin is typically used in the construction of boats, and in creating smaller objects or pieces (like surfboards).
- Epoxy glue: Epoxy glue is really just an adhesive and will bond many things together including metal, glass, stone, and more.
- Epoxy putty: Epoxy putty can be used in place of fiberglass cloth to repair any cracks or broken areas. It’s also great for repairing almost anything made out of fiberglass as it “wets” into all the small crevices like fiberglass cloth would do if placed over any cracks or holes.
Whats the difference in resins?
To start, epoxy is the name of a type of resin. Resin itself is a mix of two or more chemicals that form a liquid plastic material.
Epoxy is a two-part resin that when mixed together forms an epoxy. Both resins and epoxies are used in a wide variety of applications but they have different properties.
Epoxy tends to be more expensive than standard resins and more difficult to work with due to the requirement to mix two parts together in order to use it.
However, it’s stronger than standard resins and has many other unique properties that make it useful for some projects over just using standard resins.
Can I mix glitter in resin?
Yes, you can use glitter in resin. If you are using the resin for casting, you can use glitter to decorate the inside of the mold. If you want to add glitter to the surface of the casting, you should use mica powder or a glitter medium.
Mica powders are pigments made from minerals that have been ground down into a fine powder and mixed with an oil-based medium and wax.
They come in a wide selection of colors and they have a very sparkly finish when used in resin projects. You can also purchase ready-made shimmery glitters (as opposed to chunky ones) which are called “glitter mediums.”
Conclusion
This article hopefully helped you to understand the difference between epoxy and resin. Both are two-component liquids that are mixed together for a chemical reaction that results in hard plastic.
Epoxy is used for bonding materials together whereas resin can be used as an adhesive or to coat over an object, making it appear to be embedded in glass or other material.
Resin is generally less expensive than epoxy, but there are some applications where epoxy works better and vice versa.
We recommend trying out a small amount of both to see which one works better for you. If necessary, you can also take advantage of our mixing service and try them out without investing too much time or money into your project.
