This blog post is about how to protect epoxy resin from UV and other weathering factors. Epoxy resin is a clear, colorless liquid that cures into a hard, solid material when it comes in contact with an organic solvent and hardener. It has high resistance to chemicals, solvents, corrosion, thermal shock, and abrasion.
If you are looking for ways on how to protect your epoxy resin from UV rays then this blog post will guide you through the process of doing so!

Does Epoxy Protect Against Uv
While UV will not cause epoxy to fail, it can degrade the look of your concrete project.
This is especially true for outdoor applications that are exposed to a lot of sunlight and weather conditions. In order to protect it from fading or yellowing, you need an effective coating system such as our MasterSeal 275 Epoxy Resin Coating.
It’s one of the best coatings on the market because it offers protection against all types of environmental factors including UV radiation.
It’s highly durable and won’t fade or yellow over time.
Does Resin Block Uv Rays
UV rays are blocked by the epoxy’s ingredients, which create pigment. These pigments act as a shield against UV rays to protect your work surface and any objects placed on top of the resin.
However, this doesn’t mean that you don’t have to take precautions when using resin outside in direct sunlight or near windows where light may pass through them without being filtered out by glass.
This is because ultraviolet radiation can still penetrate most materials even if they aren’t transparent enough for our eyes to see through them easily.
In other words, just having something opaque isn’t going to stop all UV from reaching whatever it is that needs protection!
Does Sunlight Affect Epoxy
The sun’s ultraviolet rays can damage most materials, but it especially has a negative effect on epoxy.
Outdoor exposure to UV light is one of the primary causes of deterioration and degradation in epoxy resin. In fact, sunlight will cause your project to decay faster than anything else even water or air!
This means you need to learn how to protect epoxy from UV if you want your project to last as long as possible outdoors.
Does Epoxy Resin Fade In Sun
Epoxy resin does not have a tendency to fade in the sun, unlike some other products. However, it is still important to make sure that you are protecting your epoxy with enough sunscreen/sun protection as well as taking steps for proper UV protection.
How Do I Make Epoxy Uv Resistant
Epoxy resins are usually not UV resistant. However, if an epoxy resin is mixed with a hardener that contains additives to resist ultraviolet light (UV), then it can be made more durable and less likely to break down over time.
The relative amount of additives in the hardener can vary greatly, depending on where it’s purchased.
The best way to find out how well these types of UV-resistant epoxy resins are working for you is by testing them yourself.
Apply a thin coat onto some paper or other surface that will be easy to observe changes over time, then wait at least one month before checking up on your sample again.
What Finish Can I Put Over Epoxy
The answer to this question depends on what you want your final product to be. There are several different finishes that can be used for anything from a decorative look, such as paint or colored pencils, to an end-use like packing peanuts and stilts.
Can You Over Cure Resin Prints
depends on what type of epoxy system you are using. For example, if your UV source emits mostly short-wavelength light (e.g., under 400nm), then some amount of print curing can be done with visible wavelengths without actually initiating photoinitiators in the resin.
This means that while it won’t achieve 100% conversion, it will get pretty close and continue improving even after more exposure time, due to crosslinking occurring via heat generation from energy absorbed by the substrate at higher levels than would normally happen during an actual transition process initiated by a photoinitiator molecule absorbing photons within its absorption spectrum.
Will Uv Resin Cure Inside
UV resin is a liquid so it will cure in the bottle. But this takes quite some time to finish curing, and you need to do that under constant light exposure or UV radiation.
You can transfer your finished project into another container if you want to work on something else for a moment without having a cured part of the epoxy resin sitting there half-cured while you’re doing other things.
Can You Cure Uv Resin In Sunlight
Yes, UV resin can cure in sunlight as long as it is not exposed to the direct rays of the sun. In order for a full cure to occur, ultraviolet light needs to strike at an angle from above and diffuse through the epoxy layer.
Does Epoxy Need Sunlight
Epoxy resin does not need sunlight to cure and there is no specific type of light that speeds up the curing process. However, ultraviolet (UV) radiation from the sun degrades epoxy over time and should be avoided for this reason.
How Long Will Epoxy Last Outdoors
If you are unsure whether your project is outdoor-grade epoxy or not, check with the company that manufactured it to ensure that they recommend using an exterior grade as opposed to a lower quality indoor one.
What Materials Can Be Used To Protect Epoxy Resin From Uv
Any material that does not contain any phosphorous. In particular, plastics such as ABS and PVC are great choices because they will not discolor the resin in the sun or cause it to become brittle over time.
Also, metals like aluminum work well too! However, make sure you clean them thoroughly beforehand to remove any grime or oils so your surface is nice and smooth for a strong bond with your plastic.
Other options include wood items which may need a few coats of varnish if using raw lumber but this also works fine depending on what look you want after curing.
What Are Some Materials That May Not Work Well For This Application
Plasticizers and softeners such as polyethylene glycol (PEG) can leech out over time and cause the resin to become tacky.
Also, it’s best not to use anything containing sulfur or phosphorous because these chemicals will also break down the epoxy plasticizer causing problems like cracking and discoloration.
Can I Place Objects Directly On Top Of My Finished Project Once Cured
Yes, you can! Since our products cure fully under light they will be safe for indirect food contact after curing so feel free to add your artwork onto dishes, cookware, serving trays, and more!
