P-541: is a rapidly curing, addition cure silicone for use in life casting. Due to the speed in which this material solidifies, it is not recommended for common mold making purposes. Cure time can be accelerated with heat such as a hair dryer. To ensure the comfort of your model, use a mold release, such as petroleum jelly, on the body parts prior to applying P-541.
