To tint epoxy, simply use an epoxy compatible colorant and follow the manufacturer’s instructions. Typically, you would add a small amount of the colorant into the resin or into the blended resin and hardener. 2-5% loading level should have no significant effect on cure. A wide range of colorants, pigments, dyes and tints are compatible with MAS epoxies. Opaque pigments such as One-Shot Lettering Enamels, Mixol, K-Bond Color Pigments and most acrylic craft paints work well. We’ve also had great success with Gamblin Dry Pigments and Eye Candy mica powder, both metallic and flat, to get a marbled or colored effect with the MAS epoxy. Lastly, translucent dyes such as Transtint and Piñata Colors are also compatible with epoxy. Most acrylics are also epoxy compatible. Do not use water based paints or pigments like latex as they can cause foaming.
As with most projects, artwork especially so, each piece is unique. A quick small-scale compatibly test is recommended to make sure the colorant stays evenly dispersed and the epoxy cures properly. It should be noted, pigmented epoxy may be somewhat more UV resistant than unfilled epoxy, but should still be protected with a UV resistant coating for outdoor use.
