The Ignite™ line of liquid fluorescent colorants is compatible with Smooth-On urethane rubbers, plastics, foams (rigid and flexible) and epoxy resins. The fluorescent or “glow” effect is maximized under ultra-violet light or “black light.” The most dramatic color effect is realized when an Ignite™ colorant is used with a clear or translucent rubber (such as Clear Flex™ 50) or plastic (such as Smooth-Cast™ 325 or EpoxAcast™ 690).

What makes castings made with Ignite™ colorants appear to glow? When you add Ignite™ fluorescent color to a urethane material, more ultraviolet light from the cured material is visible to your eye vs. castings made with SO Strong™ colorants. Castings appear brighter in ambient light and appear to glow under UV light (black light).
