Body Double™ SILK

Body Double™ SILK is a self-releasing platinum-cure silicone rubber that can be applied directly to the skin to make molds of the face, hands and other body parts. The rubber cures quickly and will reproduce excellent detail from any original model. Certified Skin Safe - Material is skin safe and certified by an independent laboratory. 

Body Double™ SILK will release from closely cropped hair-covered skin surfaces (short beards, mustaches, eyebrows, pubic hair, etc.). Release cream or Hyper-Folic™ are not needed when using Body Double™ SILK. Body Double™ SILK will last for many castings of almost any material including plaster, Matrix™ NEO™, wax, resins (Smooth-Cast™ urethanes, polyester, etc.) Body Double™ SILK has a working time of 6 minutes and a demold time of 20 minutes*.

*Depending on material temperature, ambient temperature and body temperature – see “Preparation” below for details.
