- Mixed Viscosity: Variable.
Use Cases
Ideal for lifecasting applications such as making molds of hands, faces, and other body parts. For reusable molds, silicone rubber is recommended.
Instructions
Preparation
- Store and use in a dry environment at room temperature.
- If the powder gets warm during storage/shipping, store in a cool area (15°C - 31°C / 60°F - 70°F) for 24 hours before use.
- Use as soon as possible due to limited shelf life.
- Ensure adequate ventilation during use.
Practice
Make a mold of your thumb or something small before larger models to gain experience.
Applying A Release Agent
- Will not stick to most surfaces.
- For head molds, use hair conditioner on hair-covered areas to prevent mechanical lock.
Measuring
- Mix 1 part water to 1 part powder by volume.
- Adjust water level to change consistency; less water for thicker, more for thinner.
- Avoid too much water as it may prevent curing.
Water Quality
- High mineral content water may cause lumpiness or improper setting.
- Use distilled water if necessary, heated to the correct temperature.
Temperature Of The Water
- At 27°C (80°F), working time is 5 minutes, demold time is 8 minutes.
- Warmer water speeds up curing, colder water slows it down.
Mixing
- Hand mixing is possible, but a power drill with a mixer attachment yields best results.
- Mix for one minute to a gel-like consistency, smooth without lumps.
Pouring Around An Object
- Pour around the model in a fixed position inside a container, ensuring clearance from the bottom and sides.
- Apply a thin coating to the model surface before pouring.
For Vertical Application
- Experiment with water amount for thicker consistency suitable for vertical surfaces.
Applying A Support Shell
- Use bandages to support the alginate mold after curing.
Casting Into The Mold
- Cast into the mold within 4 hours following demold.
- Materials for casting include plaster, wax, clay, and fast urethane resins.
