Can you use a blacklight to cure resin?

Are you a resin enthusiast? If so, you need to know whether you can use a blacklight as a UV light. In this article, we will get into everything about curing resin with a blacklight.

What is Resin?

This is an organic compound that is generally used for different artistic stuff like jewelry making and woodwork. Resin contains monomers linked by covalent chemical bonds.

It has different forms and it comes in a liquid state when it’s fresh but it hardens after some time. There are different types of resins available in the market and each one serves a specific purpose.

It needs to be hardened properly before using it for any purpose as improper hardening may affect the end result of your work

While you may be tempted to use a black light, or ultraviolet light, to cure your resin or nail polish, it’s important to remember that not all ultraviolet lights are the same. Is a black light strong enough to cure resin?

The answer is no. Black lights are not strong enough to adequately cure resin.

Black lights emit UV-A rays, which are longer than UV-C rays. Because of their longer wavelength, UV-A rays do not have enough energy to cure resins and some nail polishes (which require a shorter wavelength than UV-A).

If you tried to use a black light with these products, they would never fully harden and would remain sticky.

Does any UV light cure resin?

You can’t just use any UV light to cure your resin. For example, the light in a tanning bed is way too intense to safely use on resin. The same goes for most blacklights and many LED lights. Be careful when selecting a UV light source!

You can use a blacklight to cure resin. However, certain conditions must be present first.

First, the resin you are using must be formulated for UV curing. In other words, it needs to say “UV resin” or something similar somewhere on the label. Otherwise, it will not work properly with any UV light source.

Next, you need to make sure that you are using a light that does not just say “blacklight” on it but actually emits ultraviolet (UV) light waves.

What most people call blacklights or blacklight bulbs are actually high-intensity visible light (HIVL) lights and do not produce any UV at all; they only appear dark purple due to a special coating inside the glass of the bulb itself.

Some manufacturers have begun labeling these bulbs as “ultraviolet lamps” now in an attempt to trick customers into buying something they don’t need, so if there is no mention of UV wavelengths or specific numbers like 365nm being emitted by your bulb then do some more research before making any purchases!

Will a 395nm UV light cure resin?

395 nm UV LED light. This is the exact item I bought on Amazon.

Yes, you can use a 395nm UV light to cure resin. It’s a little more complicated than using traditional UV lights, though, and it might not work for everyone. In this post, I’ll go over what exactly resin curing is, whether or not you can use a blacklight to cure resin, and how to use a 395nm light if you decide it’s something you want to try in your crafting.

How Does Resin Curing Work?

Resin curing is the process of turning uncured resin into fully cured resin by exposing it to UV rays and letting them react with the hardener in the resin mixture.

The end result is a hard plastic that won’t stick to your fingers or anything else you touch with. Of course, different kinds of resins require different kinds of hardeners, which means that each type of resin needs its own specific kind of UV light in order to cure correctly.

Since traditional blacklights emit 365 nm UV rays instead of the 405 nm ones required by most types of epoxy resins on the market today (though there are some exceptions), they usually won’t do much good for this purpose unless specifically designed for curing resins

Can resin dry without UV light?

Before you can use any UV light to cure your resin, you need to know what the difference is between hardening and curing. We want to cure our resin.

Hardening is when the resin changes from a liquid to a solid, but in order for it to be completely cured and fully hardened, you need it to change chemically. You can only do this with UV light exposure.

The good news is that there are different kinds of UV lights that you can use for this. Some of these include:

  • Sunlight – This works best if your project will be outdoors (most people don’t like working outside) because the sun has intense UV rays that work better than artificial sources. Make sure your resin artwork isn’t sitting in bright sunlight for too long as it could discolor or even melt your project over time!
  • LED Lights – These have been shown effective at curing epoxy resins and other types of adhesives depending on how close they are positioned to each other; however some LED lights may not emit enough ultraviolet rays so make sure when shopping around online or at stores what kind of power output they offer before buying them! If using an LED lamp just make sure it’s close enough without burning anything nearby like leathers or plastics.

Can a nail UV light cure resin?

Yes! A UV light designed for curing nails is a perfect alternative to a UV lamp. They typically cost less than $40 and they work just as well.

I’ve used both nail lamps and UV lights, and I’m here to tell you there is no difference between them for resin projects. The major benefits of using a nail lamp are:

  • A nail lamp can cure an entire small project in a minute or two. You don’t have to worry about which side of your piece the light will hit first or whether it will take hours to cure an entire project.
  • Nail lamps are easy to use, portable, and affordable (about $30). That makes them great if you do lots of small crafts with resin and need to move around your workspace often.

Can you use a UV light to dry resin?

Yes, you can use a UV light to cure resin.

However, not all UV lights are created equal! The wattage of the bulb is what determines how much resin you can cure with it. A higher wattage bulb emits more UV light per second and that means that you will be able to cure more layers of resin at once.

Remember that this is DIFFERENT from the power of the light itself. The power DOES NOT affect the amount of curing you can do in one go – only the wattage does this.

Does UV light cure resin faster?

Does UV light cure resin faster

Yes, you can use a blacklight to cure resin faster!

UV light is more effective than other types of light when it comes to curing resin. But not all ultraviolet lights are created equal.

Some lights expose the resin to UV rays for longer periods of time, increasing their effectiveness in the curing process. We’ll help you figure out how much UV light your project needs and which type of bulbs will work best for your needs.


The pros of using a blacklight to cure resin include:

  • You don’t need to buy new lamps or equipment.
  • The process is quick and simple.
  • It can be used for small objects such as jewelry since you can direct the light at the pieces from very close.

However, there are some cons as well:

  • A blacklight won’t work if your resin has built-in UV filters.
  • Blacklights are expensive if you need a lot of them to cover large surfaces.

In conclusion, using a blacklight to cure resin is effective, but it’s probably best used for smaller projects that require less coverage and more precision. I would recommend getting a dedicated UV lamp instead if you’re planning on doing larger scale work with epoxy resins that don’t have UV inhibitors in them.
