ROOM TEMPERATURE CURING SILICONE
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-S041 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.
