So-Strong Color Tints

Tints For Urethane Rubber, Plastic, and Foam

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. SO-Strong® colorants are highly concentrated, offer excellent dispersion and consistent color. A very small amount will color a proportionally large amount of liquid urethane material.
