Epoxy and UV resin are the two resin kinds that are most frequently used in crafts. Both of them are liked due to their appealing enamel-like look. However, a lot of beginners exchange them without realizing the differences since they believe they function the same way.

What distinguishes UV resin from epoxy, then? Epoxy and UV resin will be compared side by side in-depth in this blog article. To help you choose the best resin for your upcoming project, we’ll discuss everything from cost to working time to cure time.

What is Epoxy Resin?

Epoxy resin is just a synthetic material that is frequently used as a sealer or adhesive. A basic resin and a curing agent are the two major components. These two elements react when combined to create a strong, resilient substance. Epoxy resin is often utilized in the building and car sectors as well as in crafts and hobbies.

What is UV Resin?

UV resin is a particular kind of synthetic resin that cures under ultraviolet (UV) light. With regard to composition and characteristics, it is comparable to epoxy resin. UV resin, on the other hand, cures when exposed to UV light; it does not require the application of a curing agent. This makes UV resin perfect for uses that need speedy curing, such as 3D printing.

A comprehensive table of comparisons between Epoxy and UV Resin

The following table compares epoxy and UV resin:

Product

Epoxy

UV Resin

Preparation

It is measured and properly combined with equal amounts of resin and hardener

There is no need to prepare; ready to pour

Hardening

Takes longer to harden, between 24 and 72 hours, when using hardeners.

UV light hardens the material in around 2 to 5 minutes.

Curing Time

Epoxy takes longer than UV resin to fully cure, generally requiring 24 hours or greater

UV resin cues significantly more quickly, often in 15 to 60 minutes

Durability

In terms of strength and durability, epoxy yields better results

UV resin isn’t quite as strong as epoxy, it still has excellent outcomes

Cost

cheaper in volume

Costly in terms of volume and extra UV torch/lamp costs

Chemicals

less resistant to chemicals

uses a lot of chemicals

Strength

Medium to high

Low

Fixative

Is fixable with acetone

Is fixable with Ethanol

Frequently asked questions

What makes UV resin and epoxy different from one another?

UV resin cures under ultraviolet light, whereas epoxy is a one-part resin that must be combined before curing. Epoxy is a two-part resin. Epoxy often outlasts UV resin and is more heat- and chemical-resistant. UV resin, on the other hand, has the benefit of being far less dirty and easier to handle than epoxy.

What advantages does utilizing epoxy offer?

Epoxy offers many benefits, including dependability, heat and chemical resistance, and simplicity of usage. Additionally, it cures transparency, making it perfect for tasks that call for a clean finish.

What benefits does applying UV resin offer?

The benefit of UV resin over epoxy is that it is considerably simpler to use. Since there is no need to combine two pieces, it is also less untidy. In addition, unlike epoxy, it cures fast when exposed to UV light, eliminating the need for waiting.

Final Thoughts

So there it is—a thorough table comparing epoxy and UV resins. As you can see, each has advantages and disadvantages, so which one is better for you depends on your own requirements. UV resin is likely the best option if you require a resin that hardens rapidly. Epoxy can be a better option, though, if you want a resin that is stronger and more resilient. Whatever option you select, just be sure to carefully adhere to the instructions to ensure the greatest outcomes.
