Use Cases

Ideal for temporary molds of body parts like the face and torso. Suitable for casting materials such as plaster, wax, clay, and fast urethane resins. For soft, skin-like castings, use soft silicone rubber.

Instructions

Preparation

• Store and use in a dry environment at room temperature.
• Store in a cool area (15°C - 31°C) for 24 hours before use if the powder gets warm during storage/shipping.
• Use as soon as possible due to limited shelf life.
• Avoid moisture contact with unused powder.
• Ensure adequate ventilation during use.

Practice

• Practice by making a mold of a small object before attempting larger models.

Applying A Release Agent

• Does not stick to most surfaces.
• Use a release preparation to prevent mechanical lock to hair when molding the head.
• Apply cholesterol-based hair conditioner to hair-covered areas before application.

Measuring

• Mix 1 part water to 1 part powder by volume.
• Pack the powder firmly into the measuring cup.
• Adjust water level to change mixture consistency.

Water Quality

• High mineral content water may cause lumpiness or improper setting.
• Use distilled water if water quality is questionable.

Temperature Of The Water

• At 27°C (80°F), working time is 8 minutes, and demold time is 10 minutes.
• Warmer water cures faster; colder water extends working time.

Mixing

• Can be hand mixed, but best results with a power drill and mixer attachment.
• Mix for one minute to achieve a gel-like consistency.

Application

• Wet the model’s skin before applying.
• Apply a thin coating by brushing, smoothing by hand, or using a plastic spatula.
• Keep the model still until the material sets.
• Experiment with water amount for desired consistency.

Applying A Support Shell

• Once cured, a support shell is necessary.
• Gypsona brand medical grade plaster bandages are recommended.

Casting Into The Mold

• Cast into the mold within 4 hours following demold.
• Materials include plaster, wax, clay, and fast urethane resins.
• For soft castings, use soft silicone rubber.
