Body casting silicone rubber

Body Casting Silicone 22 is a skin-safe RTV-2 silicone rubber specially developed for applications where the material comes into temporary direct contact with the skin. This thixotropic silicone rubber is widely used for body casting, life casting, skin impressions and creating highly detailed body moulds where comfort and accurate detail reproduction are important.

Thanks to its soft and flexible properties, the silicone rubber feels comfortable on the skin and accurately captures even the finest details. Its thixotropic formulation ensures the silicone stays in place on vertical surfaces without sagging or running during application.

The silicone rubber is easy to use thanks to its 1:1 mixing ratio and short curing time. This makes it suitable for professional applications, workshops and creative home projects.

Key features of Body Casting Silicone 22

• Suitable for temporary skin contact.
• Thixotropic; will not sag on vertical surfaces.
• High tensile and tear strength.
• Excellent detail reproduction.
• Flexible and comfortable during use.
• Excellent ageing resistance.

What is skin-safe silicone rubber?

Skin-safe silicone rubber is a two-component addition-cure silicone specially developed for applications where skin contact and comfort are important. Unlike standard silicone rubbers, this formulation is suitable for temporary skin contact, making it ideal for taking impressions of hands, feet, faces and other body parts.

After mixing, the material forms a spreadable compound that can be applied easily to the skin. The silicone accurately captures fine details and forms a flexible, tear-resistant mould that can be carefully removed from the skin once cured.

How to use Body Casting Silicone 22 - for beginners and professionals

1. Thoroughly stir both components separately in their containers before use.
2. Weigh the base (component A) and hardener (component B) in a 1:1 ratio by weight (a maximum deviation of 5% is acceptable).
3. Ensure the mixing container and tools are clean, dry and free from grease.
4. Mix both components thoroughly, scraping the sides and bottom of the mixing container until a homogeneous pink colour is achieved.
5. Apply the silicone rubber to the skin within the 10-minute working time.
6. Please note: certain types of petroleum jelly, oils or other substances may inhibit curing. If in doubt, always carry out a small test beforehand.
7. Allow the silicone to cure completely, then carefully remove the mould from the skin.
