6-month UV yellowing test results Posted on 08 Apr 21:09 , 0 comments

We have an updated blog post with new yellowing information:

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

continue reading original post:




It's April 2013 (NOTE: These test results are for our BETA formula, NOT the formula we currently sell as of March 2015!  Our current formula is NON-YELLOWING!!) and we are continuing our search for a safer, clearer, non-yellowing epoxy resin (UPDATE March 2015: We did it! We currently sell only our non-toxic, non-yellowing epoxy resin on ArtResin.com)!  It has been a long process so far finding 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 epoxy resin that we are developing in its current form (NO VOCs, 1:1 mixing ratio, with HALS UV stabilizers), compared with ETI's EX-74 and Envirotex-Lite (currently these are the most common brands used in North America by artists - and the products that we currently sell and personally use in April 2013).

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, and normal use should not result in such extreme discoloring.

6 month artresin ex-74 test yellowing epoxy resin

So how did we test it this time? With 6 months of outside exposure in the hot Texas sun (including some hail, snow and 50mph winds!). All resins currently available on the market (April 2013) will experience yellowing over time, so many products have a UV stabilizer added to them to minimize and delay this unstoppable yellowing effect. We are testing alternative products because we think we can do MUCH better and we want to offer a completely non-yellowing epoxy resin product! (Click here to view our non-yellowing, non-toxic epoxy resin - available as of March 2015)In truth, it takes time, money and the motivation, not to mention first-hand knowledge of what artists want and need! We have an ASTM (American Society for Testing and Materials) number for the test so that our results can be reproduced by you!

A little info on the ASTM standards:
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.
