Ultra-soft platinum-cure RTV-2 silicone for animatronics

General Information

P-573 is a specialty platinum cured silicone designed for animatronics where small, precise movements of the robotics are required. This material is not designed for most animatronic applications. Please refer to other Silicones, Inc. silicones for a wider range of materials. P-573 is mixed 10 parts base to one part activator by weight; deviations from this ratio will cause changes in the physical properties.
