To get you started, we offer the following colorant loading levels. Results may vary.
By Weight Using A Gram Scale: Add SO-Strong™colorant at a ratio of between 0.01% – 3% of the total weight (Parts A + B mixed) of the material being cast. Adding more than 3% by weight may cause cure inhibition.
By Volume Measured In Drops: Add 10 drops of SO Strong™ per 3 oz (88 ml) of mixed urethane material. If using a translucent material (like Smooth-Cast™ 325) you can use 1 drop to maintain translucency of the material.
Directions For Use: Store and use at 73°F / 23°C. Wear vinyl gloves to prevent skin contact. After dispensing the required amount of urethane material Parts A and B into measuring containers, add colorant to Part B and mix thoroughly. Combine Parts A and B into a mixing container and mix as directed by the urethane product technical bulletin.
Blending Colors: Combine different colors on a palette to create a custom color before adding to material as directed above.
The Pantone Color Matching System is most commonly used in the printing industry to communicate color. As it relates to Smooth-On color tints and pigments, the represented color is an approximation and people’s interpretation of these colors may vary. The user will determine suitability of a color or combination of colors for the rubber, resin, foam or other product used specifically for their application. Due to the variability in products that are being colored, application, color concentration and other factors, Smooth-On makes no warranty with regards to the color.
