Are you looking for an epoxy resin that does not turn yellow?
We have two news for you: one good and one not so good.
The good news is that there is a highly UV resistant epoxy designed for maximum yellowing resistance: Resin Pro.

Why does epoxy turn yellow?
The yellowing of the resin is usually due to the breaking of polymer chains due to exposure to UV radiation. This produces small molecules, usually yellow. To solve this problem, Resin Pro introduces UV filters or anti-UV additives that can "capture" UV energy and stabilize it.
Resin Pro have been developing resins with powerful UV filters since the beginning of their production and regularly test their resistance to yellowing under UV lamps in the laboratory.
Another precaution to protect the resin is to always use opaque bottles that "protect" the resin from direct sunlight to avoid breaking the polymer chains.
To confirm the performance of UV filters in Resin Pro epoxy resin, several comparative tests were carried out in laboratories.
In the attached photos are the test results for those who are looking for "Epoxies that do not turn yellow". Resins primarily for coating and molding were compared with resins from other manufacturers after 24 hours in a UV chamber. As a "different manufacturer", Resin Pro used one of the most popular epoxy brands in Europe in a blind test, trying to be as neutral as possible in the resin comparison.
The test results showed an excellent yellowing resistance of Resin Pro epoxy.
What is the exact output of the tests?
Resin Pro epoxy products will begin to show the first signs of yellowing:
• after 5 years in the absence of exposure to the sun
• after 1 year of being outdoors
Does this mean that you need to hide, for example, your jewelry made of jewelry resin in a box and not wear them? Not at all, built-in UV filters work in the product. You absolutely do not need to worry that the product will lose its attractiveness.
Also, if you color the resin or make it opaque, you will help extend the life of your piece by a few more years!
