Hi Paul: I recently purchased some clear epoxy  and Acrylic Poly UV Plus from your company. I have access to a UV chamber which simulates high altitude direct UV exposure. I thought you might be interested in my findings. I used a Masonite panel painted white and then coated with the epoxy. On half of the epoxy coated panel, I brushed on one coat of UV Poly and put it in the chamber for 644 hours at 50 C (the heat accelerates the exposure). Attached is a picture of the results. The masonite cracked a bit and separated due to a bit of wetness in the wood (unrelated to the resin). The epoxy  ambered dramatically within about 50 hours. After 644 hours, the UV Poly showed a slight bit of ambering from the original control but it is marginal at worst. The technician who ran the test said if it isn't yellow at 644 hours it is basically indestructible. I also tested several other 2-part resin products with the UV Poly and had the same result. You have a great product. I now feel secure knowing that my resin art, protected with the Poly UV Plus, will be archival and protected for long years. I will be ordering more soon!
