We are always trying to find the best epoxy, and often times we find that it turns yellow over time. Here are some of our favorite epoxies that do not turn yellow over time.
How do you keep epoxy from turning yellow?
You might be wondering why epoxy resin turns yellow. The answer is a little complicated, but here’s the gist:
- Epoxy resin will yellow over time. Epoxy resins are made from polymers that can degrade in sunlight, which causes them to yellow. This happens when the UV rays from the sun break apart the polymer chains and make them smaller by breaking off oxygen atoms. The resulting degraded compounds give off a yellow hue that makes your project look old and dingy before its time (plus it doesn’t help that most people use older epoxies with low VOC content).
- Epoxy resin will turn faster in direct sunlight than it will indoors or out of direct sunlight (I’m talking about light bulbs here) because there’s more exposure to UV rays with indoor lighting versus natural light outdoors so it needs less time before you start seeing discoloration

Does all epoxy resin yellow over time?
There are several factors that can contribute to epoxy resin yellowing. The first is the amount of epoxy you use. The more epoxy you use, the more yellowing you will have.
As a general rule of thumb, if you plan on using a lot of epoxy (more than 50%) in your project then it’s best to choose an amber-colored resin or one that is made with UV inhibitors.
This way, not only will your project last longer but it will also retain its intended color longer as well.
Another factor that affects how much an epoxy turns yellow is exposure to sunlight and ultraviolet light. The more exposed your project is to these things, the faster it will discolor over time (kind of like how we get wrinkles under our eyes).
To avoid this problem, keep your projects in shaded areas when possible so they won’t get too much sun exposure!
What is the clearest epoxy?
Epoxy resin is the main ingredient in most epoxy products. Epoxy resins are clear and colorless, but they can sometimes be tinted into a shade of yellow or orange.
The first step in determining whether epoxy turns yellow is to look at the product label to see if it contains any pigments. If it does, then you’ll need to keep your eye out for discoloration as you apply the coating over time.
If there are no colors added to your epoxy sealer or primer, then you should never have to worry about its color changing over time.
You may still see some slight discoloration when applying these coatings though since most epoxies (including black) contain some amount of metallic content that will likely cause them to darken over time
Does epoxy clear coat yellow?
First, it’s important to know that epoxy is susceptible to yellowing if exposed to heat for extended periods of time (more than 2 hours).
This means that if you’re trying to apply the clear coat during high temperatures (over 80 degrees), your decals may start turning yellow before they get fully cured or set properly.
Second, because UV rays tend to penetrate darker colors more easily than lighter ones, dark-colored pigments in your project will also absorb more heat and therefore be subject to faster degradation by temperature changes as well.
Finally, humidity levels can affect how quickly an epoxy job gets discolored by oxygen exposure; low relative humidity levels make it easier for the air around us (which contains small amounts of water vapor) hit us with its invisible moisture molecules when we step outside on hot summer days—the result being greater oxidation rates when compared with higher humidity environments where moisture content tends toward zero percent saturation values due to exclusively atmospheric pressure effects rather than human activities such as sweating profusely after running five miles without having drank water beforehand…
Does Famowood epoxy yellow?
No, Famowood epoxy will not be yellow. This is because it’s a two-part epoxy that is clear and UV resistant. It’s also water-based, so there are no solvents to yellow over time.
Is there a polyurethane that doesn’t yellow?
Polyurethane does not turn yellow because the chemical that causes epoxy to yellow is not present in polyurethane. Polyurethane is plastic, and it does not contain any free-flowing material that can oxidize and turn yellow over time. Therefore, you shouldn’t have to worry about your polyurethane turning yellow!
While this may be good news for all you polyurethane lovers out there (no more orange hands!), it’s also important to note that polyurethanes don’t harden as quickly as epoxies do—so if you’re doing something on deadline or need an immediate result, you might want to stick with an epoxy.
What is the difference between resin and epoxy resin?
Resin is used in the production of epoxy, which is a hard and strong glue that is used to bond two materials together. Epoxy resins are liquid or gel-like substances that cure over time with the help of catalysts (hardeners).
In contrast, resin is a solid material that has not been mixed with a hardener yet.
The main difference between resins and epoxies is their chemical structure—a resin is made up of long chains of organic molecules called polymers, while an epoxy contains shorter chains made up of different monomers.
How long does it take resin to yellow?
There are several factors that will determine how long it takes for epoxy to yellow. Some are dependent on the surrounding environment, while others are dependent on the resin itself.
The first factor is temperature. Epoxies usually have different glass transition temperatures (Tg), which is the point where they turn from a solid to a liquid.
If you’re working in a warm area, your epoxy could change state more quickly than if you were working in a cooler climate—so its color would begin discoloring before you expected it to!
Another factor is humidity; this makes sense because higher temperatures typically mean higher humidity levels as well, so it’s safe to say that if your area has high levels of both heat and moisture, then your epoxy will probably yellow faster than if those factors weren’t present at all!
A third factor is UV light exposure; some resins can be sensitive enough that even just one hour under direct sunlight could cause them to yellow faster than normal (and even turn brown!).
This means if there’s not much shade around where you’re working with resin or storing materials made from them (like patio furniture), then expect things like boats and cars made out of these materials may start looking old sooner rather than later.”
you should use epoxy to protect your furniture from yellowing and water damage.
