Epoxy resin is a very popular material for bonding. It is often used in automotive, marine, and construction industries to form an extremely durable bond.
The curing time of epoxy resin can be affected by many factors including temperature, humidity, and atmospheric pressure.
This article will explore how UV light affects the curing process of epoxy resin with some helpful tips on how to get the best out of your epoxy project!
Can you cure any resin with UV light?
yes – you can cure any resin with UV light. However, it’s important to note that not all resins are created equal, so you will need to do some research before deciding which one to use.
There are a few things to consider when choosing a resin for UV curings, such as the wavelength of the light and the type of substrate you’re using.

Does UV light affect epoxy resin?
Epoxy resin can be cured with UV light, but the curing time will be shorter than if it is cured with heat.
The intensity of the UV light and the thickness of the epoxy resin layer both affect the curing time.
If you are using a UV lamp, make sure to check the manufacturer’s instructions to see how long it should take to cure the resin.
How do you cure resin with UV light?
In order to use ultraviolet light for curing epoxy resin, you need a photoinitiator. A photoinitiator is a type of catalyst that makes it possible for UV light to cure the resin into a solid.
There are many photoinitiators on the market and each one has its own advantages and disadvantages depending on how quickly it can initiate polymerization.
It’s important to know which specific initiator works best with your particular resin so you get them mixed perfectly without wasting any time or money in doing so.
In general, there are two different types of resins: thermosetting and thermoplastic resins.
Thermosetting resins have been around much longer than their counterparts but they also require more expensive equipment like induction lamps.
It’s much easier to use ultraviolet light with a thermoplastic resin because there is no need for special equipment.
can you use UV resin without UV light?
yes, you can use UV resin without using UV light. However, the curing process will be slower and it may not cure completely.
If you are looking for a faster cure time, we recommend using a UV light to help speed up the process.
does epoxy resin need uv light?
epoxy resins cure through a chemical reaction; this process does not require ultraviolet (UV) light.
instead, you must provide heat and/or pressure to the resin as it cures.
can you put uv resin over epoxy resin?
Yes, you can. As the two resins are different and do not react with each other in terms of curing, they will remain as separate materials.
This means that when an epoxy resin is used over another resin such as a UV or lacquer-based one it may result in some bubbling or cracking issues which might be difficult to fix afterward.
To avoid this problem always use either pure UV light, for instance, UV Resin cures at a much faster rate than traditional sunlight products and gives off no heat so there’s less chance of damage occurring from overheating while using the product indoors.
how long does epoxy resin take to cure under uv light?
Epoxy resins take a minimum of four hours to cure under uv light. This is the standard length of time that epoxies should be allowed to cure, however it can depend on the amount being used and what type of resin has been applied.
If there are other factors such as atmospheric conditions or high humidity, then this will also affect how quickly your product cures.
can you cure 2 part resin with uv light?
curing epoxy resin with UV light can depend on the type of resin that is used. Some resins are designed to be cured with UV light, while others may not be able to cure in this way.
It is always best to check with the manufacturer of the resin before attempting to cure it using UV light.
how to cure resin without uv light?
There are a few different ways to cure epoxy resin without using UV light. One way is to use a heat gun. You can also use an oven, or you can place the piece in direct sunlight.
If you are using a heat gun, make sure to keep a close eye on the resin and don’t let it get too hot.
If you are using an oven, set the temperature to around 150 degrees Fahrenheit and bake the piece for about 30 minutes.
If you are curing your resin in direct sunlight, make sure that it is in a sunny spot and that the piece will be exposed to sunlight for at least eight hours.
can you cure epoxy resin in the oven?
You can cure epoxy resin in the oven, but it takes a very long time. The process is simple enough: just follow your recipe and bake at 130°C for six hours or so.
But this will produce some pretty yellow-ish parts, due to heat damage on the colorant, as well as discolorations from any fillers present in the system (such as silica).
To avoid these issues especially when trying to achieve a light color with a white filler additive such as Fumed Silica it’s best to stick with curing under UV light instead of using an oven.
