MasterSil 800 Product Description

One Component, Room Temperature Curing, Silicone Elastomer System for High Performance Bonding and Sealing; Featuring Flowable, Non-Corrosive Cure and Serviceability Up to 300°C; Unsurpassed Stability at Elevated Temperatures.

MasterSil 800 is an easy to use, one component, high performance silicone elastomer compound for bonding, sealing, coating and formed-in-place gaskets. This specialty system features ultra high temperature resistance and non-corrosive cure, making it highly desirable for many applications, especially those pertaining to electronics and aerospace. MasterSil 800 is self leveling and bonds well to a wide variety of substrates, including glass, metals and many plastics. The rapidity of the cure depends on the thickness of the layer and the humidity; the thicker the layer the slower the cure. It is extremely soft with superb flexibility and elasticity and outstanding electrical insulation properties. MasterSil 800 is serviceable over the exceptionally broad temperature range of -75°F to +572°F (300°C). What is truly remarkable about the higher temperature range is that unlike other temperature resistant silicones (e.g. red silicones), MasterSil 800 will not depolymerize when exposed to 300°C and high pressure. In a sense, it can be considered a second generation high temperature resistant RTV. MasterSil 800 has a moderate viscosity, but is still flowable and is black in color.
