General Information

P-537 is a very soft, 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-537 will require a paint coating to alleviate tackiness.
