Recommended applications for Deacon 4011 liquid sealant
Deacon 4011 liquid sealant can be used as a gasket dressing to improve the sealing capability of standard gaskets. Deacon 4011 can also be applied to many types of gaskets (including spiral wound) to reseal them, thereby prolonging their useful life. Deacon 4011 can be used as the only sealant on low tolerance metal-to-metal joints. Deacon 4011 is brushed onto the sealing surface in a complete, uniform, thin coating. The coating need not be very wide, because the product will flow under compression.
Typical applications for Deacon 4011 liquid 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.
Features of Deacon 4011 liquid 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 Shelf Life
Two years in closed containers.
Instructions for applying Deacon 4011 liquid 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 liquid 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
