Material Notes:
Description: MasterSil 708FR is a one component, high performance RTV silicone that is mainly used for its flame retardancy. It is UL listed with a flame classification for 94V.1 for thicknesses of 0.75 mm and 94V.0 for a 3 mm thickness. It adheres 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 exceptionally soft with good elasticity and flexibility, and outstanding electrical insulation properties. Most importantly, it is non-corrosive, fast setting, and has a flowable consistency. MasterSil 708FR is serviceable over the broad temperature range of -45°C to +200°C, as per UL specifications, and is gray in color.Information provided by MasterBond®
