Uvo Uv-resistant Colorants 9 Pack
UVO Colorants are concentrated, phthalate-free urethane color pigments that resist ultra-violet 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.
