You will learn how to use UV light to cure resin. But before you can understand how UV light cures resin, you need to know what is actually involved in curing it.
Resin is a material that goes from liquid to solid when exposed to ultraviolet (UV) or sunlight. Resin comes in two parts: the resin itself and a hardener that makes it turn solid (polymerize).
When the two parts combine, they form polymers and cross-link with each other. This reaction forms chains of molecules called polymers, which make the resin become a solid material.
You can use UV light to cure resin if it’s not properly cured by sunlight or if you simply want your project done faster than letting it sit in sunlight for days on end

Will UV flashlight cure resin?
You’re probably diligent about making sure your resin pieces are fully cured before moving on to the next step in your project—but did you know that using a UV flashlight will help speed up the curing process?
Using a UV flashlight for curing resin is a great way to achieve full cure in no time. In addition to helping the resin harden quickly, you’ll also end up with strong, clear pieces.
Best of all, it’s easy and inexpensive!
Can I use UV flashlight to cure resin?
The short answer is: yes, you can use UV flashlight to cure resin.
It’s true that there are many ways to cure resin with UV light, but using a UV flashlight is the most convenient and effective ones.
With it, you can easily focus on the target area for curing without getting in the way of other parts or damaging any parts of your work. So if you have a UV flashlight, then you should definitely make use of it as much as possible!
The long answer would be that there are several things that need consideration when deciding whether or not this is right choice for your project:
- UV Light Intensity
Can I use a UV light for epoxy resin?
It is important to note that UV lights are not to be used with epoxy resin. Epoxy resin does not cure with a UV light; it cures with heat or a hardener.
If you try to use the UV light on epoxy resin, your resin will just stay tacky and will never cure!
What type of UV light is used to cure resin?
UV lamps are typically placed in the printers to cure resin. The wavelength of UV light is the best energy source for curing resin. You can use blue or violet light, which are both forms of UV light, to cure your resin.
By exposing your build platform and your part to the UV light, you will allow the resin to start curing it in just a few seconds.
The UV light is emitted by the lamp in the printer and then shines onto your parts and cures them as they are being printed.
Do you need a UV light for UV resin?
A lot of people ask me if they need a UV light to cure their UV resin. The answer is “yes, you will need a UV light.”
Those who are working with UV resin have probably noticed that it has no smell and stays liquid for hours after being exposed to the air.
They may have wondered, “What do we need to activate this to make it harden?”
We will definitely need a special type of light: UV Light (or Ultraviolet Light). Without UV light, there is no way your resin can be cured.
UV lights are used for many different things. For example, it is used in our smartphones, some artworks, and sculptures, etc.
You don’t see these lights obviously because they are invisible to humans. However, we can see them when using special glasses or other devices like in movies such as Men in Black 3 or on TV shows like Breaking Bad.
Will black lights cure UV resin?
- The short answer is yes. But if that’s what you’re looking for, then why are you here? Maybe you’ve heard about black lights, or UV flashlights and resin curing. Maybe you’re curious what all the fuss is about. If so, we can help!
The long answer is: yes, a UV flashlight can cure resin. Black lights are a form of UV light that can be used to cure resin. Now before you run out and pick up the first light-emitting device with the label “UV” on it – stop.
You need to be aware of a few factors before using your conventional UV light source to cure resin whether it’s an epoxy or UV resin.
It’s important to know what kind of lamp you have, and how strong it is before using it as your curing tool. Try this experiment: take one part of your body (let’s say an arm) and expose it to direct sunlight for three seconds… yep, there’s a burn already forming on your skin, but it probably won’t show up until later today when the area turns red and gets progressively worse over time.
Now imagine if we exposed our entire body to direct sunlight for three seconds… wouldn’t that be awful?
To get technical for a second: sunlight contains both ultraviolet A (UVA), which has longer wavelengths than UVC rays and does not cause sunburn; ultraviolet B (UVB), which causes sunburn; and ultraviolet C (UVC), which has shorter wavelengths than UVA rays and does not reach the earth’s surface because our atmosphere blocks them out!
How long does it take for a UV light to cure resin?
You’re probably wondering if an UV flashlight can cure epoxy resin. You’re not alone. It’s a question that many DIYers are curious about and one that is discussed often on social media channels in the crafting community.
There are several factors to consider when trying to answer this question, such as: the type of resin you are using, how thick your project is, and what you are using it for.
The short answer: no, it won’t cure resin. The long answer: yes, it can be used to cure resin but only certain types of resins and in certain situations.
The most important thing is to understand why this method works or doesn’t work so you can determine whether this is a good option for curing your projects!
Why is my UV resin sticky after curing?
While it’s possible to cure UV resin with daylight, curing time can be a long process, so it’s best to use a UV flashlight. The amount of light needed to cure UV resin depends on the type of resin you’re using.
For example, a low powered UV flashlight may work well for jewelry or small hobby pieces but won’t be powerful enough for casting or other large projects.
You can also use LED light to cure UV resin, but these lights emit different wavelengths than the bulbs in a UV flashlight and won’t work as efficiently.
If your project was fully exposed during the curing process, leave it in the sun for another day or two before removing it from your mold.
There you have it, everything you need to know about using a UV flashlight to cure resin. While it is a great option, there are some drawbacks.
It may not be the best fit for every situation. In the end, what works best will depend on your personal preferences and needs. At any rate, I hope that this article has helped you out in one way or another!
