XP-268 is a very high durometer, high modulus, platinum-catalyzed, RTV-2 silicone rubber designed for casting polyurethanes and epoxies. 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. XP-268 offers outstanding chemical and heat resistance and the rigidity to withstand the expansion of most polyurethane foams.
