Smooth-On's 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.
FeaturesColors - Black, Blue, Brown, Green, Orange, Red, Violet, White and YellowHighly Concentrated - 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.UV Resistant - Coloring resin to resist fading and yellowing from sunlight and other Ultra Violet light sources
