SO-Strong^® colorants are highly concentrated, offer excellent dispersion and consistent color.

Set of 9 Colors includes: Black, Yellow, Brown, Purple, Green, Red and Blue, White and Flesh.

SO-Strong liquid urethane colorants can be added to any Smooth-On liquid urethane rubber, urethane plastic or urethane foam (do not use with Smooth-On silicones). They can be used to create a variety of color effects for a wide range of material applications.

A very small amount will color a proportionally large amount of liquid urethane material. The more you add in proportion to the volume of liquid urethane, the more dramatic the color effect.

SO‑Strong® tints can be combined with Metal powders, URE‑FIL® fillers, or CastMagic® powders to create amazing effects. You can create spectacular casting effects in a matter of minutes vs. hours or days for hand tooling and finishing. SO‑Strong® can also be added to Brush-On® urethane mold rubber to help ensure thorough coverage between layers over the model.
