Hello! I’ve read the articles about the 3 kinds of resin: Epoxy, Polyester, and Polyurethane. I’m now confused when looking at the MasterCast artwork resin, and the TotalCast Clear Artwork resin. Both are called “Polymer Resin” in the description. Do these fall into one of the first 3 categories, or are they something totally different?
Great question! The MasterCast resin is an epoxy resin. The TotalCast resin is a ‘new generation polymer resin’. The exact ingredients are a trade secret, but it acts like an epoxy resin.
