Resin and epoxy are two substances that have a lot of similarities, but they have a lot of differences too. Let’s break down the composition, advantages and disadvantages, uses, and cost of both so you can decide which one to use for your next project.
Is resin same as epoxy?
Resin and epoxy are both polymers, but resin is generally described as a polymer that is produced from natural sources.
It can be a thermoplastic or thermoset depending on its polymerization process. Resin is popular to use in woodworking because it has good adhesion, flexibility and strength.
Polyester resin and phenolic resin are two common types of resins used by hobbyists for this purpose.
Epoxy, on the other hand, refers to any type of polymer that contains two different monomers: an oxirane group (-O-I-) linked with another functional group via an ether linkage (e.g., epichlorohydrin).
Epoxies are usually rigid materials that are very strong when cured properly and have excellent chemical resistance properties due to their tightly crosslinked molecular structure (i.e., high molecular weight).

Why do you use epoxy or resin?
- Epoxy: Epoxy is used for bonding, coating and casting. It can be used to make jewelry, molds and models.
- Resin: Resin is used for casting and molding. It’s also frequently used in sculpture.
Is resin always epoxy?
Is resin always epoxy? Well, no, not exactly. While it’s true that epoxy is a type of resin, many people use the words interchangeably when they talk about the materials themselves.
In truth, these two compounds are very different from one another and have very different uses in industry.
Let’s start with what a resin is: Epoxy resins are thermosetting polymers that cure at room temperature or above (depending on their formulation), while synthetic rubbers are cured through vulcanization at lower temperatures—usually below 200°F.
A thermoset polymer is more like glass than a liquid; it will turn into a solid if you try to melt or dissolve it again after its initial formation process has taken place.
What is the best resin to use for molds?
Resin is the best choice for mold making. It’s easy to use, you can buy it from a hardware store, it’s cheap and you can use it in small quantities.
Epoxy also works well for making molds but is more expensive and requires mixing before use (so there’s some prep work involved).
What’s the best resin to use for crafts?
Resin is a type of polymer that’s been used in the craft industry for decades, but it wasn’t until recently that it became a household name.
Resins are generally used to coat objects and create molds. They’re also great for castings, sculptures, and other pieces of art that need a smooth finish. If you’re looking for something to use in your projects and aren’t sure which resin would be best, here are some helpful suggestions:
- Polyester
This resin is the most popular choice among crafters because it’s inexpensive and easy to use. It’s also very durable once cured (i.e., hardened). Polyester resin offers maximum clarity so that your finished product will look great no matter how intricate its design is!
- Epoxy/polyurethane – these two resins fall under one category because they have similar properties; however, epoxy cures more quickly than polyurethane so keep this in mind when choosing between them
Can you put fake flowers in resin?
Yes, you can put fake flowers in resin. You can also put other small items like seashells or coins into resin.
You can also use epoxy resin to make fake flowers as well as polyester resin, which is similar to epoxy but doesn’t have an exothermic reaction when mixed
What are the disadvantages of epoxy resin?
Epoxy resin is not biodegradable and is toxic. You should wear gloves and a respirator when working with epoxy resins, and you should not handle them bare-handed or without proper ventilation because they can cause irritation to the skin, eyes, nose, throat, lungs, and mucus membranes.
Additionally, epoxy resins are more expensive than other types of woodworking adhesives. This is partly because they’re sold in small containers that contain just enough for one project — so if your project doesn’t work out as planned (or if you want to do multiple projects), then it’s necessary to buy more supplies at full price rather than using leftover materials from previous projects.
Can I mix glitter in resin?
You can definitely mix glitter in resin, and you should! We recommend mixing it with epoxy, though.
There are a few different kinds of glitters you can use in resin: holographic, fine-spun, and microfine. The best all-around option is probably fine-spun because it has a lot of shine but also doesn’t flake off as easily when applied to your project.
After applying the glitter, allow your piece to cure overnight before handling it or using water on it (you don’t want any moisture getting trapped under the glitter and causing problems).
Then wash your hands thoroughly before touching or using any other surfaces that could be damaged by oil residue from fingerprints (like silverware).
Conclusion
I think the best thing to take away from this is that there are many different types of resin and epoxy. Some would say one works better for certain projects than others, but ultimately it comes down to what you want or need out of your product.
You should also keep in mind how much time you have available when deciding which kind will work best for your project.
