Epoxy resin turns a yellow hue due to exposure to a myriad of elements. High temperatures, excessive amounts of water, and UV light can all cause the epoxy to change from clear to yellow in tint. Epoxy hardeners can also experience a yellowing discoloration that compounds the epoxy’s off-color issues.

What’s the difference between resin and epoxy?
Epoxy coating resin has a more viscous consistency as compared to casting resin. It dries or cures faster than casting resin. Compared to casting resin, epoxy coating resin has relatively shorter processing times. Epoxy coating is more resistant to mechanical influence as compared to casting resin.
Does resin jewelry turn yellow?
Once cured, epoxy resins change with exposure to UV light (as most things on earth do!). When UV light hits a resin coating, it degrades the epoxy polymers, causing ambering (i.e. a noticeable yellow discoloration). Even resin that may have started out crystal clear will soon turn a yucky yellow hue.
How long does it take for resin to yellow?
Artwork that is kept indoors will begin to discolor generally within 6 months to a year if it was coated in a resin product that contained only a UV stabilizer. If the resin did not contain a UV stabilizer at all, it will reach a dark yellowing much faster, within approximately 2-3 months.

Are epoxy table tops yellow?
Note that if the epoxy cured clear, but it’s on a table top that sits in direct sunlight, the UV exposure can make the epoxy turn yellow. To preserve the gloss and clarity of the epoxy finish, do not place items hotter than 125°F on the cured surface or it will discolor and distort.
How long does ArtResin take to cure?
Cure time refers to the amount of time it takes for the resin mixture to totally finish its chemical reaction and become its hardest state. The ArtResin epoxy resin cure time is 24 hours (hard cure), however you can touch the surface after about 8 hours without it feeling sticky. It reaches its full cure at 72 hours.
How do you whiten yellow resin?
Bleach is often used to whiten whites in your laundry, but it can also be used to remove the discoloring. Do not use straight bleach, as too much can cause the epoxy resin to soften.

Why does resin have a shelf life?
All solvent-free epoxies have essentially unlimited shelf lives so long as they are stored in sealed containers. The resin may crystallize or the hardener may darken (YELLOW) but this does not affect its performance. If the material is more than a year old do a test to satisfy yourself that it cures properly.
