UV-Resistant Pigments for Urethane and Epoxy
UVO™ Colourants are concentrated phthalate-free urethane colour 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 colour tints that can yield translucent urethane castings). For glowing fluorescent colour effects, use Ignite™ colourants.
UVO™ colourants are highly concentrated, offer excellent dispersion and consistent colour. 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.
