TC-5041 A/B is a high tear strength, addition/platinum, room temperature curing silicone rubber designed for mold making, encapsulation applications, pressure pads, gaskets, and various types of parts.  It is also used to make molds for casting low melting metals.  With the use of talc powder as an interface the TC-5041 A/B has been used with cast metal temperatures running 650°F (344°C). With the ability to withstand high temperatures the TC-5041 A/B works very well as a mask for metal spraying and welding operations.
