Life Form is a poly addition cure RTV silicone rubber that vulcanises at room temperature. A and B components are mixed together at the correct ration of 1 : 1 to offer a thixotropic mixture that is ready to be applied directly to the body. Life Form will not stick to hair due to its unique formulation. Unlike other life-casting silicones that need a barrier or release agent applied to ensure a good release, which can obscure the detail.
