Smooth-On Body Double Fast Set

Smooth-On Body Double is a long lasting 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 perfect detail from any original model – far better detail than any alginate! Body Double is skin safe and certified by an independent laboratory.

Body Double “Fast Set” for fast turnaround. Working time of 90 seconds and a demold time of about 7 minutes*.

Store and use Body Double™ 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. Mixing sticks should be flat and stiff with defined edges for scraping the sides and bottom of your mixing container.

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 release preparations or mold rubber. If you notice any type of skin reaction, do not use this product. Body Double™ 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 will cause inhibition. Prior to applying Body Double™ Release Cream, skin should be clean 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. If 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.
