Keeping UV resin from yellowing is achievable through a combination of preventative measures and maintenance. To prevent yellowing, it is important to avoid over-exposure to UV light, especially direct sunlight, both prior, during and after the curing process.
Before curing, fill any potential open spaces in the resin with a UV protectant, such as a wax or VPA, to block out any potential UV light. When curing the resin, use opaque containers to keep out UV light while still allowing the UV light to cure the resin.
Repeat this step when curing the second layer and once the UV resin is cured, always store your piece in a dark, dry place away from both UV light and heat.
Maintenance is another important factor in keeping UV resin from yellowing. Over time, UV light, chemicals and everyday wear and tear can all cause yellowing. To combat this, regularly clean and polish the resin with a mild soap and water solution, followed by a wax or VPA protectant that contains UV protectants.
Also, from time to time look for any places on the resin that may have worn away and refill with a UV protectant to ensure that the resin does not become exposed to UV light. Adhering to these recommendations will help ensure that UV resin stays clear and yellowing-free.
What type of resin does not turn yellow?
UV stabilized polyester resins are a type of resin that is specifically designed not to turn yellow over time. This type of resin prevents the oxidizing effects of light, thereby protecting the material from developing a yellow hue.
Additionally, this resin also is resistant to thermal degradation. UV stabilized polyester resins are often used in the fabrication of boat hulls, decks, and other areas that may be commonly exposed to direct sunlight.
They provide a strong, durable surface that is resistant to abrasion, chemicals, and the elements.
How long does it take for UV resin to yellow?
UV resin can yellow over time, especially when exposed to direct sunlight for long periods of time. The amount of time it takes for UV resin to yellow depends on how often it is exposed to sunlight, environmental conditions such as humidity, and the type of UV resin used.
Generally, cheaper resins will yellow faster than higher quality resins. Non-porous surfaces, such as plastic, can also help to prevent or slow down the yellowing of UV resin. In general, it usually takes 1-2 years of direct sunlight exposure for UV resin to start yellowing.
Does all resin yellow over time?
No, not all resins yellow over time. Resin is largely dependent on what ingredients are added to make it. If a resin manufacturer adds an ingredient that helps prevent yellowing, then the resin will not yellowing over time.
The yellowing of resin is caused by a few different factors. The first being the amount of UV light the resin is exposed to. UV rays can cause resin to yellow, especially if it is exposed to long periods of direct sunlight.
Another factor that can cause yellowing is reactions with certain chemicals, such as those found in some cleaning products. If a resin is exposed to these chemicals or not cured in the right way, then it can yellow.
Finally, if a resin has a high concentration of sulfur, then it can also yellow over time. In order to prevent yellowing, it is important to select a resin that is UV-stable and that has been made with ingredients to prevent discoloration from air exposure.

Does polyester resin yellow?
Yes, polyester resin can yellow over time. Over exposure to sunlight, extreme temperatures and other environmental factors can cause the epoxy to yellow and degrade. If stored correctly, this degradation and yellowing can be minimized or eliminated.
To maximize the life of the resin, it should be stored in a cool, dark, and dry area. Additionally, using an appropriate UV protectant can further reduce the risk of yellowing and degradation.
Why did my resin turn yellow?
There can be several reasons why your resin turned yellow. The most common is due to exposure to UV light. Resin is very vulnerable to yellowing from UV rays and can change from crystal clear to an off yellow hue over time if not properly protected from UV radiation and/or extreme temperatures.
Aside from UV exposure, adding small amounts of unpigmented resin during the layering process or not stirring the resin thoroughly can also cause it to turn yellow. Additionally, some pigments can oxidize over time, leading to yellow discoloration.
If you have acetone and sandpaper nearby, try lightly sanding the discolored area to remove the yellow. Finally, if the yellow is due to oxidation, a couple of drops of household bleach may be able to help remove the yellow tint.

Will epoxy yellow in the sun?
Epoxy is an incredibly durable and reliable adhesive, making it one of the most widely used adhesives in industries such as automotive and construction. It is a kind of resin which when cured becomes very difficult to break.
The answer to whether epoxy yellow in the sun is yes. Sunlight exposure will eventually cause epoxy to become yellow and discolored over time. This discoloration is most visible on white or light colored epoxy, resulting in an unpleasant yellow or amber hue.
While epoxy’s UV resistance does not stop the discoloration from occurring, it does help to slow it down. Additionally, epoxy’s inherent strength and durable properties help to ensure its longevity in outdoor applications.
The best way to prevent the discoloration of epoxy in sunlight is by protecting it from the sun’s ray. This can be done by applying a UV-resistant topcoat, untreated polyurethane, or a specialized epoxy additive which contains UV inhibitors.
This will provide the epoxy a layer of protection and slow down the discoloration process. Additionally, avoiding direct and prolonged exposure to sunlight will also help keep the epoxy looking great and protect it from discoloration.
How do you fix yellow epoxy?
Fixing yellow epoxy depends on the type and location of the epoxy. If the epoxy is unfinished and found in a workshop, the most common form of epoxy being a two-part system, the yellow epoxy may be due to incorrect mixing or incorrect curing.
In either case, the entire mixture will need to be removed and new epoxy used as a replacement.
If the yellow epoxy is on finished surfaces such as countertops or bathroom fixtures, then it is likely caused by environmental exposure. This can be fixed by thoroughly cleaning the surface and applying a fresh protective coat with a UV-blocking sealant, such as an acrylic resin or epoxy.
It is essential to use products specifically designed for the type of surface the epoxy is on, and to follow all safety and application instructions provided by the manufacturer.
When reviving yellow or degraded epoxy surfaces, it is important to perform a thorough evaluation of the affected area, including checking for signs of microbial activity, prior to cleaning or repairing any surface.
If microbial activity is present, then all visible and accessible areas should be treated with an appropriate biocide prior to cleaning and repairs.
