6 month UV yellowing test results

September 2016

FYI we have an updated blog post with new yellowing information... here's the link:

YOU ASKED: How is our new ArtResin formula better in terms of yellowing?

Atlas Labs in Arizona conducted third party unbiased accelerated weathering testing of 17 epoxy resin samples on the market. The result was that ArtResin came out on top!

See the data here:

NOTE: The info in the old test results below reflects our BETA formula, NOT the formula we currently sell as of March 2015!  Our current formula has unparalleled protection against UV damage!

We are continuing our search for a safer, clearer, epoxy resin with longterm protection against yellowing (UPDATE March 2015: We did it! We currently sell our proprietary epoxy resin formula on ArtResin.com)!  It has been a long process so far, trying to find the perfect epoxy resin for art, but we are being patient and working hard! Thanks for all of your interest so far.

The photo below shows the ArtResin BETA epoxy resin formula that we are developing, in its current form (NO VOCs, 1:1 mixing ratio, with HALS UV stabilizers), compared with another popular epoxy resin manufacturer's products. 

As you can see, ArtResin epoxy resin is visibly less yellow! 

TO BE CLEAR to the readers of this blog post:  This test was done in extreme conditions (outdoors 24/7), and normal use should not result in such extreme discoloring.

So how did we test it this time?
With 6 months of outside exposure in the hot Texas sun (including some hail, snow and 50 MPH winds!). All resins currently available on the market as of April 2013 will experience yellowing over time, so many products have a UV stabilizer added to them to minimize and delay this effect. We are testing alternative products because we think we can do MUCH better and we want to offer a better epoxy resin product with much better, longterm clarity! (Click here to view our non-toxic epoxy resin formula with exceptional protection against UV damage - available as of March 2015)In truth, an endeavour this large takes time, money and the motivation, not to mention first-hand knowledge of what artists want and need! So we're working diligently and trying to have patience.

We have an ASTM (American Society for Testing and Materials) number for our test so that our results can be reproduced by anyone, including you! A little info on the ASTM standards from their website: 

ASTM International, formerly known as the American Society for Testing and Materials (ASTM), is a globally recognized leader in the development and delivery of international voluntary consensus standards. Today, some 12,000 ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. ASTM’s leadership in international standards development is driven by the contributions of its members: more than 30,000 of the world’s top technical experts and business professionals representing 150 countries. Working in an open and transparent process and using ASTM’s advanced electronic infrastructure, ASTM members deliver the test methods, specifications, guides, and practices that support industries and governments worldwide.
