Tech Specs

O-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. For glowing fluorescent color effects, use Ignite™ colorants.

Features

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. The more you add in proportion to the volume of liquid urethane, the more dramatic the color effect. Recommended loading range is .01% to 3% of total system weight. Do not overload the liquid urethane system or cure inhibition / oozing may occur.

User determines amount to add; If this is your first time adding color tint or pigment to a urethane system, you may want to test the color effect by adding a few drops to a small amount of urethane material and observe the outcome. It may take a few test castings to attain the desired color outcome.
