Master Bond MasterSil 155S is a two component electrically conductive silicone compound for high performance bonding and sealing. The specifically modified silver filled silicone resin after the addition of a liquid curing agent cures at ambient or more quickly at elevated temperatures to a tough, flexible, electrically conductive silicone rubber. The tightly controlled viscosity of this silicone elastomer formulation produces a smooth paste which assures complete fill-in around complicated contours in even very complex configurations and provides excellent electrical conductivity as well as superior resistance to vibration and shock after cure. It has been widely accepted for bonding and/or sealing of electronic components, electrical devices and various electro-optical systems as well for special electronic circuitry or wherever a tough, elastic electrically conductive adhesive, sealant or gasket offering superior protection against adverse environmental conditions is required. MasterSil 155S has a service temperature range of -85°F to +400°F.
