I had a potential customer in yesterday, looking to get some polyurethane printed. It is a polyether based polyurethane, or so he told me, I'm unfamiliar with it. So, we're looking for an ink that 1) will stick, chemical bond, and 2) be abrasion resistant, due to rough treatment. Any ideas? I know an air dry epoxy would be pretty tough, but I'm concerned about the abrasion resistance...
