Urethane Plastics
Technical Sheet - Adding Colorants and Fillers
COLORANTS
CU Pigments & UD Dyes are to be mixed with Urethane Resins (Rubber and Plastic) and are also compatible with Epoxy Resins. Mix the colorants into the B component until desired color is achieved. Recommended percentages for proper mixes are 1% ‑ 2% of the Total Mixed Weight (A and B combined) to component B. Mixing proportions greater than 2% may drastically affect physical cure.
Example: A B Pigment
Grams 100 100 2 = 1%
100 100 4 = 2%

FILLER
Many fillers are available in extending plastic mixtures. They are used for economics, color, texture, improved properties and thermal conductivity. The filler of your choice should be free of moisture which can react with the A (Isocyanate) side and cause foaming or a pitted surface. Mix the filler with one side or the other. A Jiffy Mixer may be required if the filler does not blend in smoothly resulting in a lumpy mixture.
