P-50 is a high durometer, platinum-catalyzed, RTV-2 silicone rubber designed for casting
polyurethane and epoxy molds. It is easy to mix and de-air, and will cure with virtually no
shrinkage. The speed at which the rubber hardens can be dramatically accelerated with heat
or with Pt Accelerator at room temperature. Addition-cure two-component silicone rubbers
may show inhibition sensitivity. P-50 offers outstanding chemical and heat resistance and the
rigidity to withstand the expansion of most polyurethane foams.
