Fast-cure platinum-cure RTV-2 silicone for body molding

General Information

P-541 is an RTV-2 platinum cured addition reacted silicone. It was developed for use as a mold making material that can rapidly reproduce body parts. Due to the speed at which this material cures, it is not recommended for common mold making purposes. It is advised that the model apply Vaseline to the area of their body that is going to be copied. There are some instances where the silicone has pulled hair. If something other than Vaseline is to be used, a small amount of material should be tested, as some lotions can cause outgassing in your mold. P-541 has only a three to five minute work time and a demold of ten to fifteen minutes. Any deviation in heat from 70°F can either increase or decrease these times.
