Loctite 88545 540 Core Plug Retaining Compound Anaerobic Sealant 250ml Blue

Loctite 540 is a thixotropic anaerobic retaining compound designed for sealing core plugs and many other high strength sealing applications where non-migration is desired. The thixotropic nature of LOCTITE 540 reduces the migration of liquid product after application to the substrate. This blue-colored liquid sealant comes in a convenient 250ml bottle and provides reliable, permanent sealing for critical automotive and industrial applications.

Key Features:

• Thixotropic anaerobic sealant designed for sealing core plugs and high strength sealing applications
• Easily applied with LOCTITE applicators and prevents rusting in the threaded engagement area
• Chemical-resistant with excellent resistance to oils, fuels and hydraulic fluids
• Fixture time of 60 minutes at 72°F, full cure in 24 hours at 75°F
