UV resin is a type of synthetic resin that can be used to make polyurethane foam. It is a colorless, highly combustible liquid resin.

Typically, some people are sensitive to UV resin.

Is UV Resin Toxic

However, if exposed to a small amount of this chemical, you are highly unlikely to experience any adverse side effects.

The adverse effects can be more severe in case of overexposure to significant levels of UV resin over a long period or if it comes into contact with your eyes or skin.

So, how toxic is UV resin? This article will address this question. Continue reading to learn more.

Is UV Resin Toxic?

Definitely YES! You need to understand some important facts before using UV resin. There are no known cases of toxicity caused by inhalation or dermal exposure.

However, if you ingest resin, it can cause nausea, vomiting, and diarrhea. You can also experience irritation to the skin and eyes in case of direct exposure.

Effects of Resin on the Environment

UV resin is a type of material commonly used to coat surfaces and protect them from damage. You can apply it on floorings, walls, furniture, countertops, etc.

When exposed to sunlight or UV light, it hardens to create a protective layer on the surface.

UV resin has various benefits for your home or business but also comes with some drawbacks. The following are five different ways resins  can adversely impact the environment:

  1. Resin is toxic to aquatic life. If brought into contact with water and sunlight, it can cause damage to fish and other aquatic animals in your pond or lake.
  2. Resin reacts with oxygen when exposed to air and water at high temperatures, which may lead to toxic fumes getting released into the air around your home or business premises. These fumes can irritate the body’s internal organs if inhaled.  They can also affect the growth of plants in the surrounding area and kill them off entirely if exposed for a long time.
  3. Resin production releases methane into the atmosphere. Methane is another GHG that can produce a warming effect that’s 23x more than carbon dioxide over 100 years! Methane is released into our atmosphere during the production of copolymer resins which reacts with oxygen or water vapor in the air.
  4. Resin production releases methane into the atmosphere. Methane is a GHG that contributes to global warming and climate change. It is produced when organic matter (such as trees) decomposes without oxygen. Producing resin requires lots of organic matter to be processed, which results in methane being released into the environment.
  5. Resin production releases volatile organic compounds (VOCs) into the atmosphere. VOCs are chemicals that quickly become vapors at room temperature and pressure. They include solvents, paint thinners, lacquers, gasoline, kerosene, and benzene. VOCs can cause eye irritation, headaches, and nausea if inhaled in large quantities. Long-term exposure may contribute to cancer or congenital disabilities in people.

Safety Precautions When Working with Resin

Working with UV resin can be a fun and rewarding experience. However, it is crucial to consider precautions to ensure you are safe while handling it.

The following are important safety tips to help keep you safe while working with this material:

Full Body Protection

One essential precaution when working with UV resin is to ensure that your entire body is covered with protective clothing. Wearing safety clothing helps protect the skin from the sun and any harmful chemicals and provides a barrier between you and the finished product.

Consider these full-body protection tips:

Always Wear Protective Eyewear

When working with UV resin, wear some safety glasses if you have sensitive eyes or if you wear contacts most of the time. It is one sure way of saving your eyesight from any potential damage or irritation that may occur from the ultraviolet radiation emitted by this material.

Use Chemical-resistant Gloves

UV resin doesn’t cause instant irritation in case of exposure to open skin. However, it can irritate your skin if you are highly allergic or sensitive to specific ingredients like dye or fragrance contained in resin.

To prevent this, wear gloves while working with resin or keep your hands away from your face while curing it so that nothing gets into your eyes or mouth accidentally (which could irritate).

UV Resin Fumes

When using UV resins, there are two main types:

Both types produce toxic fumes when heated, so it is important not to breathe them in or have them come in contact with your skin or eyes. These fumes can also cause damage to wood, metal, glass, and plastic objects if they come into contact with them while they are hot.

Ensure to use a respirator mask with a HEPA filter when handling the resin fumes or to cut your finished piece because dust particles produced during these processes can be harmful if inhaled.

Other Safety Precautions areas are listed below:

Don’t Eat or Drink While Using Resin 3D Printer Resin

It’s best not to eat or drink anything while working with UV resin. The chemicals in the material are not good for your body and could cause adverse effects if ingested.


Use caution when using UV resin in areas with low ventilation, such as basements or garages. The fumes produced by this material can quickly build up in these areas and potentially lead to serious health complications if not properly vented.

If you’re unsure how to ventilate your workspace safely, consider hiring an electrician or contractor to handle the job more professionally.

Don’t Use Any Part of Your Body to Mould the Resin

Use tweezers or other tools to manipulate the resin instead of your hands when working with UV resin. It will help prevent burns from any spillage or splatter from getting on your skin.

Keep Any Leftover Product Away From Children or Pets

They may accidentally ingest small amounts while playing around with your work area or pieces of jewelry that are still drying after curing.

Maintain Cleanliness and Order

Ensure to clean up any spills immediately before they dry and become difficult to remove from hard surfaces such as countertops and floors.

Using Different Types of Resin

Resins are polymers that are used in the manufacturing of various products. They can be natural or synthetic, polymers or copolymers.

Resins come in multiple forms, such as mixtures, liquid solutions, and solid materials.

The resin itself is usually an organic compound that has been modified to create a polymer. This process may involve cross-linking, where chains of molecules are connected to form a network.

The uses for resins vary greatly depending on the type of resin being used. For example, some resins are used as coatings for wood or metal to protect them from wear and tear.

Others are used to create plastics or synthetic rubber. The most common resins include:

This resin is primarily used to create fiberglass insulation and marine plywood because it has a high thermal resistance and can withstand moisture damage.

It’s also available in different grades based on hardness and flexibility levels.

This resin type is often used in flooring because it provides excellent resilience and dimensional stability under constant loads.

Polyurethane Resin can maintain these characteristics over time without losing strength or elasticity. This can be primarily attributed to its increased potency, unlike other urethane foam compounds.

Acrylic resins are used to create high-quality prints with exceptional clarity. This material has excellent transparency and gloss, making it a favorite among artists and designers who want to create patterns with high definition. Acrylic resin is also easy to use and can be tinted with any color.

It is not as strong as polyester or epoxy resins, but it is cheaper than both types of resin.

This type of resin gives your object a hard finish that can withstand even harsh weather conditions like rain or extreme heat.

Epoxy resin is widely used by people who live in humid areas where they have to keep their belongings safe from moisture damage caused by rain or humidity.

The downside of using epoxy resin is that it takes longer to dry than other UV resins, so this may not be suitable for you if you’re working on an urgent project.

How to Deal with Toxic Substances

The resin can be easily used in a wide range of temperatures and environments without causing any severe damage to the human body or the environment.

However, many people have concerns about how to deal with toxic substances. So how do you deal with toxic substances?

As mentioned above, one essential way to maintain safety is to pay attention to personal protective equipment (PPE). For example:

Also, always read instructions carefully before using a product containing a toxic substance to know whether there are special instructions for its use (for example, avoid contact with eyes and skin).

If you have any doubts about whether a product is safe or not, stop using it immediately until further notice from a specialist who is better placed to offer recommendations and safety guidelines.

You don’t have to keep using something just because someone told you it was okay; always ask yourself if the product is safe or harmful to your health, then seek an expert opinion before purchasing the product.


Is UV Resin Safe?

UV resin is made from a combination of chemicals and UV light. As a result, it has a high concentration of monomers that can be harmful to your health if inhaled or ingested.

But the mixture of these ingredients also makes the resin so effective at what it does: hardening and setting quickly.

Is UV Resin Toxic Before/After Curing?

No! It is unsafe to handle the uncured resin directly or touch it with your hands. You should always wear gloves when handling uncured UV resin.

And after curing the resin, you should wash your hands thoroughly with soap and water before eating or drinking anything.

Do You Need to Wear a Mask When Using UV Resin?

You don’t need to wear a mask when using the toxic UV resin kit. However, if you want to avoid inhaling any vapors from the curing resin on the lamp or curing machine, you should wear a mask or respirator.

This is especially important if you use the cured resin indoors without sufficient ventilation.

Is UV Resin Safe to Use Indoors?

Yes, the UV resin kit is safe for indoor use because of its low odor and low VOC content (volatile organic compounds).

However, we recommend that you use your resin outside or in an open space or if indoors, the room should be sufficiently ventilated so that fewer fumes in the air may irritate your eyes or nose.

Is UV Resin Safe for Skin?

It is much safer to use UV resin with protective gear. The goal is to protect yourself from potential harm that may irritate you. However, it does take some time for your body to get used to this material, so expect some initial discomfort when using this product for the first time.


UV resin is an excellent product for any professional nail tech or at-home manicurist. You can use it to create 3D nails or add some extra bling to your designs.
