There is only one epoxy resin formula available on the market that includes both UV and HALS stabilization: that product is ArtResin epoxy resin. ArtResin was developed specifically for use over artwork and craft projects, meaning it has been formulated to keep artwork beautiful and as the artist intended, over time. Any resin product that does not include both HALS and UV stabilization will, as a matter of scientific fact, amber and yellow over a period of a few months to a year (typically). A low quality resin product applied over artwork will deteriorate the work and decrease its value, leaving both artists and patrons frustrated and disappointed. In that sense, choosing to use a cheaper resin product is actually an extremely costly mistake.
