Recommended Applications: Deacon 770-L can be used as gasket dressing to improve the sealing capability of many gaskets. Deacon 770-L can also be applied to many types of gaskets (including spiral wound) to reseal them, thereby prolonging their useful life. Deacon 770-L can be used as the only sealant on low-tolerance metal- to-metal joints.
Deacon 770-L is brushed onto the sealing surface in a complete, uniform, thin coating. Note: Deacon 770-L 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: Turbine Split Casing, Any Metal to Metal Joints, Pump Casing, Leaking Gaskets, Boilers, Threaded Fittings, Doors, Steam Traps, Stacks, Sight Glasses, Flanges, Nuts & Bolts, Heat Exchangers, Pressure Vessels.
Features: Ease of application. Achieves seal before full cure. Fast, easy repairs. High-pressure tolerance, high temperature tolerance, and high chemical tolerance. Solvents, Oils, Steam, Liquors, Hydrocarbons. Creates a mechanical seal. High wear resistance. Unaffected by thermal cycling. Applications as a gasket dressing. Deacon 770-L improves the sealing capability of many gasket materials.
Shelf Life: Two years in unopened containers
- 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 (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.
