Pre-mix before dispensing. Store and use all materials at or near 73°F/23°C. Quarry Tone® fillers must be kept dry. Use with adequate ventilation. Read and follow directions for resin used to mix with Quarry Tone® fillers. The following example features Smooth-Cast® 325 (A+B) mixed with Quarry Tone® powder. The powder must be thoroughly dispersed into a two component liquid resin or rubber to a uniform consistency.
Recommended Mix Ratio by Volume:
1A + 1B + 2 Parts Powder Filler.
By Volume Mixing & Casting Procedure:
Dispense 1 cup of Smooth-Cast® 325 Part B into a clean mixing container.
Dispense 2 cups Quarry Tone® powder into mixing container.
Mix thoroughly.
Dispense 1 cup of Smooth-Cast® 325 Part A into mixing container.
Mix for 30 seconds until all filler particles are dispersed and pour into rubber mold.
Guarding Against Moisture – All powders will absorb atmospheric moisture over time which will react with urethane resins. If you notice a moisture reaction between resin and powder or suspect that your Quarry Tone® powder contains moisture, you can remedy by spreading powder evenly over a metal cookie sheet at ¼” (0.6 cm) thickness and bake in oven for 4 hours at 150° F/60° C. Allow to cool before mixing powder with resin. Store powder tightly closed container in a cool, dry environment with a desiccant pouch (available at your local hobby/arts and crafts store). Replace used desiccant pouches every other time you open container.
