UVO™ Colorants are concentrated, phthalate-free urethane color pigments that resist ultraviolet light. By adding a small amount of UVO™ to a Smooth-On epoxy, urethane rubber, plastic or foam product, these pigment dispersions will yield opaque castings (vs. SO-Strong™ color tints that can yield translucent urethane castings). For glowing fluorescent color effects, use Ignite™ colorants.
UVO™ colorants are highly concentrated, offer excellent dispersion and consistent color. A very small amount will color a proportionally large amount of liquid epoxy or urethane. The more you add in proportion to the volume of liquid material, the more dramatic the color effect. Recommended loading range is .01% to 3% of total system weight. Do not overload the liquid system or cure inhibition / oozing may occur.
