MasterSil 800Med is a ready to use, one component, high performance silicone elastomer compound for bonding, sealing, coating and formed-in-place-gaskets. Its forte is high temperature resistance with serviceability up to +572°F. While curing, it is non-corrosive, especially to electronics. It bonds well to a wide variety of substrates, including silicone rubber.
MasterSil 800Med is a condensation curing silicone and the rate of cure depends upon the level of humidity and the thickness of the layer. The higher the humidity the faster the cure and thinner sections cure more rapidly than thicker ones. MasterSil 800Med has a relatively fast tack free time, as noted below. Its color is black. It is primarily used in applications where a medical grade RTV silicone needs to operate from temperatures ranging from -75°C up to +300°C. Silicones are not typically used for conventional autoclaving because of their problematic resistance to steam. However, it should be noted that MasterSil 800Med has superb resistance to dry heat and sterilization.
