What is UV Resin:

If you’re wondering what UV resin is and if it’s better than epoxy resin, then you’re in the right place. UV and UV led resin is an alternative to conventional epoxy resin. It belongs to Synthetic resins and is best used as a fast-curing resin. Unlike this resin, which needs a hardener, UV resin cures entirely within a few minutes by chemical reaction with the help of sunlight or a UV lamp. Additionally, it’s best to use fast-curing resin as it doesn’t need any hardener. As a result, UV resin or UV led resin is preferred for projects that need to be fast-tracked, such as architecture, jewelry making, or product design. In summary, if you’re looking for a resin different from conventional epoxy resin, UV resin is a great option.

What is Epoxy Resin:

Epoxy resin is a type of resin that is used in a variety of industrial applications. It is a type of reactive prepolymer and is composed of epoxide groups. These epoxide groups make this resin react with catalysts or co-reactants, leading to the resin’s various properties and applications. It is mainly used in industrial applications due to its high mechanical properties and resistance to chemicals and heat. It is also used in aircraft components due to its high thermal and chemical resistance.

Advantages of UV Resin

UV resin requires a short time – usually within minutes or seconds by a chemical reaction on UV lamps or sunlight. This makes it easy to use – just buy it, place it in direct sunlight or under a UV lamp, and let it do its job. Additionally, UV led resin is excellent for curved surfaces as compared to other types of resin. So, if you have difficulty deciding which resin to buy for your project, UV resin should be your go-to choice!

Disadvantages of UV Resin

There are a few disadvantages of UV resins. The UV resin is comparatively expensive compared to other resin types. Another downside of UV resin is that it is mainly used for a very thin layer, usually no thicker than 3 mm. Furthermore, the resin’s durability is not as high as other types of resin. In terms of finish, UV resin usually produces a less durable crystalline finish. Additionally, you will need a transparent mold to allow UV light to cure the resin. Lastly, UV resin needs a UV lamp to cure it, which can be expensive.

Long Time to Cure

UV resin and Epoxy both take time to cure but Epoxy takes about 1-12 hours to cure. Depending on the type of resin used, the cure time may vary. That’s why it is difficult to work with epoxy resin when you need to repair or craft something quickly.


Epoxy resin is expensive compared to other resins because it is a two-part system that needs to be mixed before use. Mixing the two parts is much more than the cost of the two individually.

Strong Fumes

The fumes from epoxy resin are quite strong and unpleasant to breathe in. You must wear a mask while mixing this resin or working with it. It also gives off a strong smell that may stay in your clothes for a long time. The fumes can also cause headaches and nausea.

Slippery When Wet

When you apply epoxy resin to a surface, it can get quite slippery when wet. It can be difficult to work with because it is tricky and hard to grip.

Poor UV Resistance

Epoxy resin does not perform well under direct sunlight. This means that you will have to do a lot of work inside, and you won’t be able to use the resin when needed.

Poor Water Resistance: When you mix epoxy resin, you will have to keep it in a dry environment. If there is moisture in the air, the resin will get contaminated and not perform well.

Can Cause Respiratory Illnesses

As we mentioned before, this resin emits toxic fumes when curing. These fumes can cause respiratory illnesses if exposed to them for extended periods. If you are working with this resin, it is important to make sure that you are wearing a respirator to protect your lungs.

Ripples Can Be Seen After Some Time

The other issue with epoxy resin is that ripples can be seen after some time. If you mix the resin properly, then the surface will be smooth. But if you mix it improperly, you will end up with ripples on the surface. If you want to avoid ripples, then you should mix the resin properly.

UV Resin vs Epoxy Resin

We hope you have got an idea about those 2 types of resin. Now we will focus on Uv resin vs epoxy resin. So let’s start-

Mixing and Curing Process

The biggest difference between these two resins is in their mixing and curing process. Epoxy resins are two-part resins that need to be mixed before use, whereas UV resins are one-part resins that can be used straight out of the bottle.

Epoxy adhesives need to be mixed in the correct ratio of the two parts before use. If not mixed correctly, the epoxy resin will not cure properly and will remain tacky. UV resins do not need to be mixed as they are already in the correct ratio and ready to use.

Curing Time

Epoxy resin’s curing time is more and also need heat to harden properly where UV resin’s curing time is very less. UV resins are cured with UV light and do not need any extra heat further.

Types of Projects

When it comes to large projects, epoxy resin is often considered the best choice as its thickness can withstand more pressure and be tougher than UV resin. On the contrary, UV resin is ideal for projects that need a flexible and durable finish with thin layers. UV resin is perfect for eyeglasses and ornaments where durability is key. Epoxy resin also has a higher maximum thickness compared to UV resin (1mm vs. .5cm).

When it comes to cost, epoxy resin is generally more expensive than UV resin. This is because the epoxy resin is a two-part system that requires the use of a hardener, while UV resin only requires one component. In addition, it usually has a longer curing time than UV resin, which means you will need to purchase more to complete a project. However, epoxy resin is typically more durable and longer-lasting than UV resin, so it may be worth the extra expense in the long run.


The main difference between the two resins is that epoxy resin is stronger and more durable than UV resin. Epoxy resins can be used for various applications, including coating floors and countertops and even repairing wood.

UV resins are not as strong or durable as epoxy resins but are much cheaper. UV resins are often used in crafts and models because they cure quickly under ultraviolet light. However, UV resin is not as heat resistant as epoxy resin, and it can yellow over time.

Shelf Life

In terms of shelf life, UV resin has a shorter shelf life than epoxy resin. This is because UV light will cause the photo-initiators in the UV resin to break down over time, resulting in a decrease in the quality of the resin. Epoxy resin, on the other hand, does not suffer from this problem as it is not exposed to UV light. Therefore, it has a longer shelf life.

Which Product is Best for You?

When picking between UV resin and epoxy resin, it depends on what you intend to use the resin for. UV resin is the better option if you need a quick curing time and a strong bond. However, if you are looking for a more durable product that can withstand high temperatures, then epoxy resin is the better pick. Ultimately, it all comes down to your specific needs and what you plan to use the resin for. Other factors to consider include price, ease of use, and toxicity.

Epoxy resin is more expensive than UV resin but is also more durable and long-lasting. It takes longer to cure, but the result is worth the wait. Epoxy resin is also more difficult to use, so it is important to follow the instructions carefully. This type of resin can be toxic if inhaled, so be careful to work in a well-ventilated area.

UV resin cures quickly when it exposures to ultraviolet light. It is not as strong or durable as epoxy resin, but it is much easier to use. It is also less toxic, making it a good choice for people with allergies or sensitivities. However, UV resin can yellow over time and may not be as clear as epoxy resin.
