P-50 SILICONE RUBBER
P-50 is a two-component addition cure silicone rubber mold making material. It has a high durometer,
superb physical properties, minimal shrinkage and extreme chemical resistance making it an excellent
choice for prototyping, casting urethane foam and other plastics. P-50 cures at room temperature in
18-24 hours; however, the curing rate can be accelerated with Pt Accelerator at room temperature or
with heat.  P-50 is a good choice for Pewter casting due to its -60 to 600 degree F temperature range.
