As we all know, resin variety is vast and diverse. Thus UV resin has been proved an effective choice in application by history, which can date back to ancient Egypt. There they first used sunlight to cure resin to coat the insides of their sarcophagi. Nevertheless, UV resin still plays a more significant role in various fields currently, like cosmetics, medicine, automobiles and more.
Without any further ado, let’s take a look at its definition
UV resin is a type of resin with a one-part, nonsolvent adhesive, which polymerizes and cures in a short time when exposed to ultraviolet rays (UV). And UV curing is also called UV bonding or UV coating. Thanks to its fast curing speed, ultraviolet rays resin has been widely used in jewery, eletronic parts, automative, wood, cable etc .
What Advantages does UV Resin have?
- Fast curing time
- Clear and glossy finish
- Low shrinkage
- Non-toxic and low odor
What are some polular application fields?
Jewelry making
Do you know: UV resin has been popular in jewelry making, such as pendants, earings and other jewelry pievces. The main reason is that it can help achieve clear, glossy and durable coatings.
Lens making
Generally the whole process is easy. Firstly, just clean the mold and then pour the resin into the mold. Then put the mold under a ultraviolet rays lamp to cure the resin. Finally remove the lens from the mold. Done.

Step 2: Cure with the UV lamp after the coating. And it should be done within three minutes.
Step 3: Apply further layers as you wish and cure accordingly.
Step 4: Done.
UV resin VS epoxy resin
1 Difference in components:
UV resin is a one-part resin which is instantly ready for use.
Yet, epoxy resin offers 2-part epoxy resin because it consists of a resin and a hardener.
2 Curing
With regard to curing way, UV resin cures by the use of ultraviolet rays, while Epoxy resin cures without other aids.
3 Layers
UV resin requires thin layer. As we know, its maximum layer thinkness is 1 mm, but epoxy resin allows its thickness up to 5cm per casting.
4 Small areas VS large areas
Ultraviolet rays resin is always suitable to apply on small areas because it needs a ultraviolet rays lamp to cure. And epoxy resin can also be applied on large areas, such as indurstrial floors.
Frequently asked questions
So what is the best way to color UV resin?
There are several ways to colour the resin.
1 Add liquid paint or pigment powder to the resin in a mixing cup and mix them carefully.
2 Add a few drops of expoxy resin pigment to the resin
3 Add colored powder and mix it thoroughly.
4 Add crystal transparent epoxy resin dye
5 Add a few drops of black alcohol ink and then add the pigment powder. This can achieve a dark and rich color.
How to prevent air bubbles from forming in UV resin?
I know, Bubbles can be really frustrating when it comes to resin. Many friends have asked about this question. Here are some tips for preventing air bubbles in the use of UV resin.
1 Done’t use wooden mixing tools. There are two reasons. One is that wooden tools usually contain air themselves. The other is that wooden tools have textured surfaces which can create bubbles.
2 Use plastic mixing tools.
3 Also, you can allow 5 to 10 mins for the mixed resin to rest before pouring into the mold because in this case, bubles can rise to the surface.
4 Softly and carefully mix to avoid introducing air into the mixture.
5 Apply thin layers each time.
6 Pop surface bubbles after poring into the mold
7 Warm up the space/oven-safe molds to reduce surface tension.
