Availability: In stock (19)

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.

Store and use Body Double™ SILK at room temperature (73°F / 23°C). Warmer temperatures will drastically reduce working time and cure time. Storing material at warmer temperatures will also reduce the usable shelf life of unused material. This product has a limited shelf life and should be used as soon as possible. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.

Safety - We recommend that you do a small scale test on the back of your hand to ensure that you have no allergic reaction to the mold rubber. If you notice any type of skin reaction, do not use this product. Body Double™ SILK is safe for skin application only – it should not be ingested. Do not use to make molds of the inside of the mouth. You can make molds of a smile - parted lips with teeth exposed, but closed together.

Avoid Open Eye Contact - In making a mold of the face, applying this silicone to closed eyes (after applying Body Double™ Release Cream to avoid encapsulating eye lashes) is common practice. At no time should this or any other Smooth-On material come in contact with open eyes.

Life casting is best done with at least three people. You will be working with materials that set up quickly. One person is the designated model and the others will mix and apply mold rubber and support shell.

Cure Inhibition - Contaminants on the skin may cause inhibition. Prior to applying Body Double™ SILK, skin should be clean, dry and free of make-up, cosmetics, skin creams, oils perfumes, etc. Do not apply rubber over skin coated with an aloe-based product, as this will cause cure inhibition. Do not use latex gloves. When using a bald cap, make sure it is latex free.

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.

RELEASING BODY DOUBLE™ SILK - Body Double™ SILK is designed to not encapsulate body or facial hair such as closely cropped beards, moustaches, eye-brows, pubic hair, etc. A release cream or additive is not required in most cases. If performing a full-head lifecasting, use of a non-latex bald cap is recommended. A small test application to determine suitability of release properties is recommended.

PRE-MIXING - Stir Part A and Part B thoroughly before dispensing.

After pre-mixing Parts A and B, dispense equal amounts into a mixing container (1A:1B) and aggressively hand mix, making sure that you scrape the sides and bottom of your mixing container to attain a uniform color and eliminate any color streaks
