| P-44 is a translucent, medium viscosity, high tear strength, platinum-catalyzed, RTV-2 silicone rubber, which was 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 be dramatically accelerated with heat or with Pt Accelerator at room temperature. Addition-cure two-component silicone rubbers exhibit excellent chemical and heat resistance, but may show some inhibition sensitivity. P-44 is supplied with 2 Activators: P-44A (1) is used for production molds, while P-44A (2) is used for casting clear parts. P-44 is extremely useful for prototype applications where superior mechanical properties are required. |
