Deacon 8875-THIN High Temperature Sealant

Sold by: Each

Availability: In stock

Deacon 8875-Thin is a thermal reactive paste sealing compound that is used in high temperature and high pressure applications. In the presence of heat, Deacon 8875-Thin will form a mechanical (“mechanical type”) seal. Deacon 8875-Thin will not cement the flanges or threads together, thus, it will not interfere with future repairs of metal-to-metal joints. Deacon 8875-Thin is unaffected by thermal cycling.


Temperature Range: 150°F to 1800°F.

Recommended applications for Deacon 8875-Thin sealant

Deacon 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 sealant

Threaded 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.

Instructions for applying Deacon 8875-Thin sealant

  1. Surface should be clean and dry (free from oil or foreign material to ensure proper sealing/adhesion)
  2. Apply a thin coat to sealing surface with brush or putty knife (if sealing threads, apply only to the male threads)
  3. Close and tighten joint (torqued to the equipment manufacturer’s specifications if sealing a bolted flange)
  4. 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-Thin

The 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 hrs
  • 400°F --- 4 hrs
  • 500°F --- 3 hrs
  • 600°F --- 1 hr
  • 700°F + --- <1 hr
