Deacon 8875 Sealant Paste & Thin

Operating Temp: 200ºF to 950ºF / 93°C to 510°C

Deacon 8875 is a thermal-reactive sealing compound. Operating Temp: to 1350°F / 730°C

Deacon 8875 Standard Paste is a thick, fibrous, thermal reactive paste sealant/refractory hybrid used in high temperature and high-pressure applications. In the presence of heat, Deacon 8875 will expand and form a mechanical (“mechanical type”) seal that is not weak or brittle like ceramics. 8875 won't cement flanges together so it will not interfere with future repairs of metal-to-metal joints. Deacon 8875 is unaffected by thermal cycling.

Application Procedure: Deacon 8875 is troweled onto the sealing surface in a complete, uniform coating. Note: Deacon 8875 will flow filling small voids and surface irregularities, creating a seal between the gasket and the flange surface where most leak problems originate. Deacon 8875 can also be used as a standalone compound on metal-to-metal flanges that are warped, cut, or pitted.
Typical Uses: Turbine Split Casing, Any Metal to Metal Joints, Pump Casing, Leaking Gaskets, Boilers, Doors, Steam Traps, Ductwork, Stacks, Flanges, Heat Exchangers, Gaskets Dressing, Exhaust Systems. Deacon 8875 can be used as a gasket dressing to improve the sealing capability of many gaskets. Deacon 8875 can also be applied to many types of gaskets (including spiral wound) to reseal them, thereby prolonging their useful life. Deacon 8875 can be used as the only sealant on low-tolerance metal-to-metal joints.
