Quarry Tone™ Granite FX Fillers are specially blended powders that can be added to some Smooth-Cast™ liquid plastics or liquid rubbers to create realistic stone effects in finished castings. There are 10 granite effects powders to choose from, each with its own particle size and color.
For best results, use Quarry Tone™ powders with a fast-curing translucent resin such as Smooth-Cast™ 325. The fast curing resin allows uniform filler dispersion throughout the finished casting. If the resin system is too slow, fillers may settle unevenly in the finished casting. Quarry Tone™ powders can also be added to translucent / clear silicone rubbers such as Dragon Skin™ or EcoFlex™ Series for granite-like props that are soft and flexible. Quarry Tone™ powders can also be blended to create additional finished effects.
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:
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.
Make your resin casting look like granite, sandstone, limestone or more
