What is UV resin?
UV resin belongs to the group of synthetic resins. Compared to conventional epoxy resin, however, there are significant differences, especially in the way it is processed.
- UV resin cures completely within a few minutes with the help of a special UV lamp
- It can be used immediately without the need to mix it with a hardener
- Only thin layers can be cast
The advantages and disadvantages of UV resin
- The laborious mixing of resin and hardener is no longer necessary.
- The resin can be used for a very long time, as it does not cure without the aid of a UV lamp.
- Curing by UV light is completed within a very short time.
- The shelf life is only 6 months.
- The cast layers should not exceed 3 to 4 mm. After that, several layers should be cast for safety reasons
It is somewhat more expensive than conventional epoxy resin.
- A special UV lamp is required for curing. The UV radiation of the sun is only partly sufficient in our latitudes.
Application possibilities of UV Resin
Like any other material, fast drying resin has both advantages and disadvantages. However, there are some objects for which the use of UV resin is simply unbeatable.
- For smaller projects like resin jewellery and other small castings UV resin is the right choice
- UV Resin can be applied excellently on small areas for sealing
- Due to the short curing time the UV resin is practically unrivalled as an epoxy resin adhesive
Buy LED Resin: The best UV resin for your projects
From our UV resin comparison, the Limino UV Resin emerged as the clear winner thanks to its transparency and very good quality. Compared to other UV LED Resin it forms relatively few air bubbles and cures under UV light within a very short time. We were also convinced by the relatively low price for which this high-quality resin is available.
Other material needed for working with UV Resin
- A UV lamp or UV flashlight
- Casting moulds made of silicone in the desired size and shape
- Colour pigments or liquid ink for resin
- Additives such as glitter or mica flakes
- utensils for mixing resin and paint (mixing cup, stirrer)
- Package totally have 18 items
- It includes 1 sphere silicone casting mold, 1 cube silicone resin casting mold, 1 diamond silicone casting mold, 1 triangular pyramid silicone casting mold, 2 silicone casting mold measurement cups, 2 different crystal stone shape resin casting molds, 10 wood sticks
- Are made up of silicone, very flexible and easy to clean and it re-usable, not easily damaged.
- This resin mold kit includes: heart mold, round mold, ellipse mold, rectangle mold, square molds, tweezer, finger cots
- Very suitable for making resin coasters, jewelry holder, flower pot holders, bowl mat etc.
- Made of high-quality silicone, very flexible and durable, the finished product is very shiny and transparency
Guide for your first UV resin project
- First cover your workplace with foil or cardboard and put all the necessary materials within easy reach.
- If you want to use a colored resin, put some of the resin together with some liquid paint or pigment powder into a mixing cup and mix the two components carefully but thoroughly with a stirrer. Afterwards the resin can be poured into the provided silicone mould. If you want to work with crystal clear resin, the step of coloring is of course not necessary and the resin can be poured directly into the mold.
- Pour the UV LED resin in an approx. 3 mm thin layer into the silicone mould.
- A particularly beautiful effect is achieved by incorporated elements such as glitter particles, mica flakes, dried flowers or luminous pigments. These are placed either on or directly in one of the resin layers.
- The following part is the most important: Drying the resin layer under UV light. Here it is definitely worthwhile to invest a little more money when purchasing a really powerful UV lamp or UV torch. This is now held and maintained for a few seconds very close above the surface of the resin. To test if the layer is cured, you can check the condition of the surface with a toothpick in between.
- Repeat the steps to pour in resin and dry until you have filled your silicone mould.
As the resin is completely cured under the light source, the casting can be removed from the mould immediately afterwards.
Caution: The chemical reaction during the curing of the resin causes a strong heat development. Take care not to burn yourself on your workpiece.

What you should pay attention to when buying UV lamps
When purchasing a suitable UV lamp, the performance and the size of the interior should be the deciding factors. The output should be at least 4 watts. This is the only way to make use of the great advantage of UV resin, the curing within a few minutes, even for larger workpieces.
Hint: To cure unusual, bulky shapes or several pieces at the same time, it is important to ensure that the interior of the lamp is sufficiently large.
Basically, we recommend that you give preference to a UV lamp over a UV flashlight. These are simply much more practical to use, as you can simply hold or place your work piece under the light source to dry and do not have to hold it all the time. Furthermore, UV lamps usually have a much higher output than corresponding flashlights.
The curing time of UV Resin
The exact duration of the curing process depends on several external factors and also on the nature of the workpiece itself. If you have made a small jewellery pendant, then you will need on average 120 to 180 seconds each for the drying of the individual layers. If the layers are thicker or the work piece is larger, the curing time will of course be extended accordingly. External factors that influence the curing time include humidity or the ambient temperature.
Surface sealing with UV resin
If you want to seal the surface of a smaller area such as a paper surface or a very small stretcher frame, then this is possible without any problems with UV resin.
Make sure that you apply the first layer as thin as possible. A fine brush is particularly suitable for this purpose. If this layer is too thick, cavities or bubbles will form. These cannot be removed afterwards.
Tips & Tricks
- When working with UV resin patience is essential to achieve a perfect result. If you take enough time, pour thin layers of resin and harden them, you can prevent air bubbles from forming in the resin, which then have to be removed.
- If some air bubbles have formed in the resin, they can easily be removed with a hot air dryer. To do this, you run the hairdryer over the resin in quick movements. Be careful not to stay in one place for more than 1 to 2 seconds at most. As the heat can cause vapours to form, you should carry out this procedure in a well-ventilated room. It is also extremely important that you protect yourself with gloves, a face mask and safety glasses.
- UV resin is very sensitive to heat compared to normal epoxy resin. If it gets too hot, an acrid smell will develop. Therefore the temperature at the hot air dryer, if it is used, should be kept as low as possible.
- With the embedding of different elements in the resin, the risk of blistering also increases. In order to keep this as low as possible, you should make sure that the elements to be embedded are placed flat on the resin layer and pressed well into the uncured resin.
How to cure UV Resin without sun?
For a good curing result, you need around 4 watts to have a curing time of around 2-3 Minutes. The best suitable UV lamps are Nail curing lights or UV Flashlights.
How to color UV Resin?
The good news: You can use all kind of colours, that you also use for Epoxy Resin. These are basically: Epoxy Resin colour pastes, Alcohol Inks, Airbrush colours and pigments.
