| TC-5045 A/B is a room temperature, addition/platinum curing silicone rubber designed for mold making, encapsulation applications, pressure pads, gaskets, and various types of parts. It is an exccelent mold making material for casting low melting metals in continuous operations to 650°F (344°C) and sporadic applications of 850°F (454°C). TC-5045 A/B has proven to be less inhibited in its cure than standard platinum based silicones. It has a very favorable CTE for heat expandable mandrels used in composite tooling. |
