L250 Threadlocker (High Strength)

Description

L250 Threadlocker (High Strength) is a single component, high strength (permanent) anaerobic thread locker. The product cures when confined in the absence of air between close-fitting metal surfaces.

  • Clean male and female threads before assembly with an absorbent tissue paper to remove any cutting oil.
  • Apply the adhesive with a 360 turn to leading threads of the male and female fittings.
  • Use an absorbent tissue paper to wipe off excess jointing compound in the direction of the thread.
  • Assembly parts and hold on for 24 hours at 22-24°C to ensure full curing of jointing compound.
  • For disassembly, use hand tools to remove mating parts. When it is hard to dissemble at room temperature, apply local heat until reaching 250°C and disassemble while hot. Then, remove any residual cured adhesive mechanically and clean parts with a proper solvent, acetone.
  • Formulated to lock metal fasteners;
  • Particularly suitable for larger threaded fasteners, e.g. studs and all applications where maximum strength is needed.
  • Prevents corrosion of assembled parts.
