Description
This high-performance platinum cure liquid silicone compound is used for creating skin effects, movie special effects, production molds, medical prosthetics, and cushioning applications.
Dragon Skin™ 10 MEDIUM is suitable for industrial applications within a temperature range of the cured product of -54°C to 232°C.
Features
- Time-tested material for skin and creature effects, offering infinite color effects with pigments or powders.
- The cured rubber is certified skin-safe.
- Easy to use with a mix ratio of 1A:1B by weight or volume. It can be thinned or thickened and cures at room temperature with negligible shrinkage.
- Flame rated, meeting UL-94 HB specification and B1 classification for the GB 8624-2012 Fire Test to Building Material and Products

Instructions
Safety
Use in a well-ventilated area. Wear safety glasses, long sleeves, and rubber gloves. Only use vinyl gloves as latex gloves will inhibit curing. Store and use at room temperature (23°C). Warmer temperatures reduce working and cure time.
Cure Inhibition
Silicone rubber may be inhibited by contaminants like latex, tin-cure silicone, sulfur clays, certain wood surfaces, newly cast polyester, epoxy, tin cure silicone rubber, or urethane rubber. Test compatibility with a small-scale test. Apply a clear acrylic lacquer to the model surface to prevent inhibition. Allow sealer to dry thoroughly before applying rubber.
Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.
Note: Even with a sealer, platinum silicones will not work with modeling clays containing heavy amounts of sulfur. Do a small scale test for compatibility before using on your project.
Applying A Release Agent
Not usually necessary, but Ease Release™ 200 can make demolding easier. Lightly brush the release agent over all surfaces with a soft brush, then mist and let dry for 30 minutes.
Measuring and Mixing
Pre-mix Part B thoroughly. Mix Parts A and B (1A:1B by volume or weight) for 3 minutes, scraping sides and bottom. Vacuum degassing is recommended. Pour mixture in a single spot at the lowest point of the containment field.
Curing / Post Curing
Allow rubber to cure for 5 hours at room temperature before demolding. Optional post curing: expose rubber to 80°C (176°F) for 2 hours and 100°C (212°F) for one hour. Allow mold to cool before using.
If Using As A Mold
Silicone rubber molds exhibit natural release characteristics. No release agent is necessary when casting wax or gypsum. Use Ease Release™ 200 when casting polyurethane, polyester, and epoxy resins.
Thickening and Thinning
THI-VEX™ is used for thickening. Silicone Thinner™ lowers viscosity but reduces tear and tensile strength. Do not exceed 10% by weight of total system.
Mold Performance & Storage
Physical life depends on use. Clean molds with soap solution and dry before storing. Store on a level surface in a cool, dry environment.
