LOCTITE® LB 771
Features and Benefits
Silver, thick, metallic heavy-duty, high temperature, nickel-based anti-seize lubricant paste. It resists galling and corrosion and reduces wear.
LOCTITE® LB 771 is a silver, thick, metallic heavy-duty, high temperature, nickel-based anti-seize lubricant paste. It resists galling and corrosion and reduces wear in heavy pressure applications. It contains tenacious metals, oils and graphite materials. It is used in applications with an operating range of -54 °C to 1315 °C (-65.2 °F to 2399 °F).
- Contains tenacious metals, oils and graphite material
- Resists galling and corrosion and reduces wear
- Exceptionally resistant to attack by acids, ammonia, acetylene and vinyl monomer
- Allows easy disassembly of parts after exposure to corrosive or hot environments
- Reduces friction for tight assembling of stainless steel threads and press fits
- Lubricates and seals pipe threads in acid environments and coats gaskets in high temperature applications
- Typically used in applications with an operating range of -65.2 °F to +2,399 °F (-54 °C to +1,315 °C)
- Nickel content stays intact up to 2,399 °F ( 1,315 °C)

How to
Step by Step Guide
1. Cleaning
It is recommended to use LOCTITE SF 7063 or LOCTITE SF 7070 to degrease and clean surfaces prior to applying LOCTITE Anti-Seize lubricants.
2. Application
Apply a light coating of the anti-seize lubricant to the parts requiring protection. For threaded fasteners, use a brush to apply a 360 degree band of the lubricant to the circumference of the male fastener. Work the product into the thread roots for proper performance and protection.
3. Assembly
For threaded assemblies, thread the coated fastener/male fitting into the nut/female fitting, and then back it off and reassemble to ensure even coverage of the lubricant. Tighten with hand tools to proper torque requirement.
