What is UV resin?

UV resin is a type of resin that hardens or cures rapidly when it is exposed to ultraviolet light or direct sunlight. Presented in transparent liquid form, it is characterized by its direct application from the container, without mixing components, and its ability to mimic the appearance of glass upon curing. Because of its ability to cure in minutes under the UV lamp, it has become a popular product in arts and crafts. In addition, it allows encapsulating objects and working in layers.

It is a must for our wargames and miniatures. It is perfect for artists and modelers who want to look for realistic ways to create water effects or toxic effects in their dioramas. They usually create a water effect of pure transparency, but there is also a fluor version that creates a fluorescent effect with a unique glow-in-the-dark result when approached with a UV flashlight. 

It has a gel-like viscosity and is applied directly to the base of the miniature. It has an ultra-fast drying time when combined with an ultraviolet flashlight, taking between two and four minutes. 

It should be noted that it will remain in a liquid state permanently until ultraviolet light or daylight hits it. While that happens, you can spread and rectify its application as needed. Once the desired shape is achieved, apply light on it to dry it completely and harden it. If after doing this you notice that it remains sticky to the touch, it is because there has been a problem with the UV light, either because of the amount or the intensity of the light. If the flashlight has very low batteries or if the flashlight is very dirty it could directly affect the curing.

It is advisable to apply a gloss varnish once it has dried as it gives a more striking effect to the original color generating more visual transparency as well as eliminating the sticky effect when it is not completely cured.

This product does not have to be mixed with any other component to harden, only ultraviolet light should be used. Sun curing is also possible and will take 5 to 10 minutes on a sunny day. This time is reduced to between 90 and 240 seconds by applying curing light. It can be tinted with different dyes available on the Green Stuff World website.

Advantages of Ultraviolet resin

Buy UV resin compared to epoxy, has many advantages that facilitate our work to create or replicate toxic or radioactive waste, among others.

These are some of them:

  • Ultra-fast drying when ultraviolet light is applied to it. Even in the sun, it will not take more than 10 minutes if it is directly hit. 
  • It does not shrink. There are other materials of similar characteristics that do shrink when drying, but in this case, the shape and the amount added to the figure will remain the same when it has dried. This makes us feel confident with the application and we do not waste the product, which is always welcome.
  • It is multi-layered. Whether you want to hide something or add volume, you can apply multiple layers on top of each other without leaving marks in between.
  • It can be easily cut, polished, and manipulated once cured. 
  • If air is trapped in it, it only needs to be heated a little to expel it before it has cured.

How to color transparent ultraviolet resin?

Coloring UV resin is a fairly simple process as it is thermosetting and does not need to be mixed to cure, unlike epoxy. To do it, it is only necessary to have a specific dye for this material of the desired color, available on the Green Stuff World website. The steps to color it are as follows:

  1. Place in a plastic cup the amount of product you need.
  2. Add the dye for resins. We recommend not to apply more than 5% of dye to the mixture, which is equivalent to one or two drops of the liquid.
  3. With a suitable spatula, mix until it is evenly tinted.
  4. Place the result on the mold, base, or diorama of your choice and dry.

The process of choosing the dye is vital for an optimal finish. It mustn't contain alcohol, because alcohol produces a chemical reaction with which it will lose several of its properties. Therefore, the best option is always to use the dyes offered by the same brand.

How to dry with a UV lamp?

This product is a type of polymer that cures or hardens when exposed to ultraviolet light. Curing time will depend on the intensity of your UV light and the amount of product used in the application. If we are using daylight, it could take longer.

Here is a general process for curing them:

- Prepare your work area: It dries quickly, so it's important to have everything you need ready before you start. Make sure you have a clean, flat surface to work on, and gather any tools or materials you will need, such as gloves, a UV lamp, and a mixing cup.

- Pour it: Once the base, diorama, or desired mold is ready, you can pour it into it. If you are using a mold, make sure it is clean and dry.

- Cure it: Place it under a black light lamp or a torch, or expose it to natural sunlight, until it is fully cured. This can take anywhere from a few minutes to an hour, depending on the type of ultraviolet resin you are using and the intensity of light.

- Remove it: Once it is fully cured, you can remove it from the mold or surface. If it is stuck, you may need to gently flex the mold or use a tool to pry the already cured part free.

If you are having trouble curing it, try adjusting the distance of the lamp or increasing the intensity of the light. You can also try using a different type of UV lamp, such as a flashlight or a nail dryer.

Is UV resin toxic to be used indoors?

Both the odor and toxicity levels are lower than traditional methods, making it more comfortable and pleasant to use. Although its use indoors is not potentially dangerous, it is necessary to maintain some precautionary measures during the process.

Before starting to work with this product, be sure to be in a ventilated area, as it can give off vapors during the curing process. In addition, to avoid direct contact, it is necessary to wear nitril gloves and, if the context requires it, even protective goggles and a painting mask.

Finally, the handling of this type of material should be done away from children or pets to protect them from possible splashes of the product, and it should be stored in a place that is difficult for them to access.

Tips for using ultraviolet resin

Since this is a special material, certain care must be taken with it.

For example, it should be in a dry and ventilated place, with a temperature between 18° and 25 °C. Extreme temperatures, whether hot or cold, could damage the material and its performance.

Once the product has been opened, it should be consumed within a maximum of 10 months.
