Smooth-On So-Strong Color Tints

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). So-Strong colorants are highly concentrated and offer excellent dispersion and consistent color. A very small amount will color a proportionately large amount of liquid urethane material. The more you add in proportion to the volume of liquid urethane, the more dramatic the color effect. Recommend loading range is .01% to 3% of total system weight. Do not overload the liquid urethane system or cure inhibition/oozing may occur.
