Loctite LB 771 Nickel Anti-Seize Lubricant 500g

Loctite LB 771 Nickel Anti-Seize Lubricant is a non-curing, nickel-based anti-seize made from mineral oil, nickel and graphite. It is a thick, metallic silver paste, and Henkel states the nickel content stays intact up to 1,315 °C.

Henkel lists it for reducing friction when assembling stainless steel threads and press fits, and for easy disassembly of parts after exposure to corrosive or hot environments. It is exceptionally resistant to attack by acids, ammonia, acetylene and vinyl monomer.

Where this product is used

• Drop forge dies and hammers

Key specifications

Selecting the right option

For a paste with no free metals that is compatible with stainless steel and nickel alloys see Loctite 51606 Heavy Duty Anti-Seize 510g; for a graphite-based thread lubricant see Loctite LB 8504 Graphite Synthetic Anti-Seize Lubricant - 454g.

Loctite LB 771 is not a high-speed load-carrying lubricant. Check the limits below before choosing it for bearings or high-stress bolts.

Using it

Henkel describes it as a lubricant that reduces friction for tight assembly of stainless steel threads and press fits, and that lubricates and seals pipe threads in acid environments.

The Henkel data sheet gives no step-by-step application directions.

Storage and handling

Store the unopened container in a dry location, optimally between 8 °C and 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product.

Limits and safety

Not recommended for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidising materials. Do not use on ball or roller bearings or on parts where lubrication is critical; it is not a high-speed load-carrying lubricant. It is not recommended for high-stress grade 8 bolts where stress corrosion may occur. Read the safety data sheet before use.
