Deacon 4011-P High Temperature Paste Sealant
Deacon 4011-P is a thermal reactive paste sealing compound that is used in high temperature and high pressure applications. In the presence of heat, Deacon 4011-P will form a mechanical (“mechanical type”) seal. Deacon 4011-P does not cement joints together, thus it will not interfere with future repairs of metal-to-metaljoints. Deacon 4011-P is not affected by thermal cycling.
NOTE: Sealant material must be confined within a joint, as opposed the being applied topically.
Temperature Range: 600°F to 1350°F.
Recommended applications for Deacon 4011-P paste sealant
Deacon 4011-P can be used as a gasket dressing to improve the sealing capability of standard gaskets. Deacon 4011-P can also be applied to many types of gaskets (including spiral wound) to reseal them, thereby prolonging their useful life. Deacon 4011-P can be used as the only sealant on low tolerance metal-tometal joints. Deacon 4011-P is applied onto the sealing surface in a complete, uniform, thin coating. The coating need not be very wide, because the product will flow under compression.
NOTE: Sealant material must be confined within a joint, as opposed the being applied topically.
Typical applications for Deacon 4011-P paste sealant
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.
Features of Deacon 4011-P paste sealant
Ease of application. Achieves seal before full cure. Fast, easy repairs. High pressure tolerance, high temperature tolerance & high chemical resistance. Unaffected by thermal cycling. Improves the sealing capability of standard gaskets. Seals flange irregularities (scratches, warpage, cuts, pits).
Deacon 4011-P Shelf Life
Two years in closed containers.
Instructions for applying Deacon 4011-P paste sealant
- Surface 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 4011-P paste sealant
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.
- 500°F --- 4 hrs
- 600°F --- 2 hrs
- 700°F + --- <1 hr
