Deacon 8875-THIN (10.3 oz. Tube) High Temperature Sealant, 150°F to 1800°F
RECOMMENDED APPLICATIONS FOR DEACON 8875-THIN SEALANTDeacon 8875-THIN can be used as gasket dressing to improve the sealing capability of many gaskets. Deacon 8875-THIN can also be applied to many types of gaskets (including spiral wound) to reseal them, thereby prolonging their useful life. Deacon 8875-THIN can be used as the only sealant on low-tolerance metal-to-metal joints.Deacon 8875-THIN is caulked or troweled onto the sealing surface in a complete, uniform, thin coating. Note: Deacon 8875-THIN will flow filling small voids, and surface irregularities creating a seal between the gasket and the flange surface where most leak problems initiate.TYPICAL APPLICATIONS FOR DEACON 8875-THIN SEALANTThreaded Fittings, Turbine Split Casing, Any Metal to Metal Joints, Pump Casing, Leaking Gaskets, Boilers, Doors, Steam Traps, Ductwork, Stacks, Sight Glasses, Flanges, Nuts & Bolts, Heat Exchangers, Gaskets Dressing, Exhaust Systems, Pressure Vessels.DEACON 8875-THIN FEATURESEase of application. Achieves seal before full cure. Fast, easy repairs. High pressure tolerance, high temperature tolerance, and high chemical tolerance. Hot Air, Solvents, Oils, Steam, Liquors, Hydrocarbons. Creates a mechanical seal. High wear resistance. Unaffected by thermal cycling. Applications as a gasket dressing. Deacon 8875-THIN improves the sealing capability of many gasket materials.DEACON 8875-THIN SHELF LIFERefrigeration will extend shelf life to one year in unopened containersINSTRUCTIONS FOR APPLYING DEACON 8875-THIN SEALANTSurface should be clean and dry (free from oil or foreign material to ensure proper sealing/adhesion)Apply a thin coat to sealing surface with brush or putty knife (if sealing threads, apply only to the male threads)Close and tighten joint (torqued to the equipment manufacturer’s specifications if sealing a bolted flange)Product will cure in service with heat (See Note)Note: In high pressure applications or when pressure testing at ambient, it is recommended to pre-cure with a heat gun, oven, or to dry fire / blow down at atmospheric (running heat without pressure). Unlike silicone or epoxy products, our thermosetting sealants require heat to cure. CURING DEACON 8875-THINThe following is a general guideline for the time required for a full cure at various temperatures. A seal will be achieved before a full cure is reached.300°F — 6 hrs400°F — 4 hrs500°F — 3 hrs600°F — 1 hr700°F + — <1 hr
