UV Resin Vs. Epoxy Resin [What’s the Difference] – ResinAffairs

Hello there, what’s up today? How are all your crafting funs going on?

I hope that you’re making it great as always!!!

By the way, I’ve seen that many of the audiences are stuck in the battle of UV resin vs epoxy resin. They might have literally heard of these two types and having a hard time choosing the best type of resin for their artworks.

Well, things aren’t much complicated, though!

Before we head on to solve this puzzle, let me just give you a simple note; “Epoxy” and “UV are just two small parts of the greater “Resin” family.

Difference between Traditional Epoxy vs. UV Resin

While epoxy and UV resins perform the same task, they’ve some noticeable differences. Understanding how they vary will help you choose the ideal type of resin for crafts.

Luckily, distinguishing them isn’t that hard. And I’ve actually accelerated the easiness way further with all the essential factors put up together in one place;

1. How They Look

The simplest way to distinguish between epoxy resin & UV resin is by looking at their packaging. Epoxies usually come in 2 parts; resin and hardener, whereas UV adhesives are available in a single bottle.

2. How They Work

UV resin involves in a photochemical reaction to cure. It’s ready to pour onto the mold and needs some kind of ultraviolet light treatment to set. You might use a UV Lamp or, put it under direct sunlight to start curing.

Epoxy, on the contrary, does not require any light treatment. It can cure even at room temperature since the hardener in it triggers the curing process.

3. Mixing Process

As we’ve mentioned above, an epoxy resin comes in 2 separate parts; a hardener and resin. Therefore, for the reaction to take place, you must combine these components in a certain proportion. This measurement is defined by the manufacturer. Some could be 1:1 or even some products require mixing in other ratios.

However, this is not the case with UV resin. It comes in a single bottle containing already mixed and ready-to-use material. You don’t have to go through the time-consuming mixing process. Instead, you can instantly jump into making beautiful DIY craftworks.

4. Curing Time

Epoxies tend to have longer curing than UV resins since they take about 24 to 72 hours. For this reason, epoxies are not ideal for urgent applications.

On the other hand, UV resin can cure for as little as 2 minutes. So, if you’re in a rush, they are the perfect option for you.

5. Versatility

When it comes to versatility, epoxies are more suited for a wide range of applications. You can make coasters, bookmarks, keychains, shaker charms, or even use them to finish coating your kitchen or bathroom countertop. So epoxy is suitable for tasks like casting in molds, craft decorations, surface protecting, and so on.

The same cannot be said for UV resins, though! They are more like to be designed for specific applications. It’s actually polymerized by ultraviolet lights to use for coating, bonding, or sealing surfaces.

6. Cost

As for the cost, UV adhesives are more costly than epoxies. Besides, if you live in areas where natural sunlight isn’t strong enough, this cost may go up further. That’s because you may be forced to buy a UV light, which is necessary to promote the curing of UV resins.

7. Shell Life

Lastly, UV resins have the durability of about 6 months. Contrarily, if epoxies are stored properly, they can last for a year. This clearly says that UV-made products are more long-lasting than its counterpart. So consider that and make sure you pick the best version for your art projects.


In fine, both UV resin and epoxy have benefits and drawbacks. However, regardless of the differences, they’re both effective and perfect on their own applications.

And hopefully, I was able to bring up their differences to you. I also hope that now you know what kind of resin to choose for your craft works and take on this fun hobby to the next level. You can try out both types without getting confused.

If you’re learning things by the way, I encourage you to try out both of these types. That’ll help you get acquainted with things to sort out your future works more accurately.
