P-125 is a translucent, high tear strength, platinum-catalyzed, RTV-2 silicone rubber, whichwas designed for casting parts where visual inspection is required. It is easy to mix and de-air,and will cure with virtually no shrinkage. The speed at which the rubber hardens can bedramatically accelerated with heat or with Pt Accelerator at room temperature. Addition-curetwo-component silicone rubbers exhibit excellent chemical and heat resistance, but may showsome inhibition sensitivity. P-125 is extremely useful for prototype applications where superiormechanical properties are required.
