Loctite 222
Colour:
opaque fluorescent
purple
Anaerobic product suitable or low-strength locking of retaining, adjustment and precision
fasteners.
All traces of lubricant must first be removed using the specific activator.
Loctite 242
Colour:
fluorescent blue
Anaerobic product that prevents loosening of all types of nut and bolt; used in place of con-
ventional mechanical locking systems.
Used for medium-strength locking.
All traces of lubricant must first be removed using the specific activator.
Loctite 243
Colour: opaque
fluorescent blue
Alternative product to 242; oil tolerant and so can used on lightly lubricated surfaces without
prior use of activator.
Loctite 270
Colour:
fluorescent green
Anaerobic product for high-strength locking of bolts and studs that do not normally require
disassembly.
Parts must be heated to approximately 80°C for removal.
All traces of lubricant must first be removed using the specific activator.

Loctite 703
Product used for degreasing and cleaning parts prior to application of Loctite anaerobic prod-
ucts; after drying, promotes uniform curing of threadlockers.
Loctite 747
Product used for specifically for treatment of passive metals prior to use of slow-cure anaer-
obic threadlockers(series 5 and 6).
Can also be used to increase cure speed at low temperatures or in applications where there is
large gaps between the parts.

Loctite 510
Colour: red
Super-rapid anaerobic sealant for sealing between rigid metal faces; can eliminate the need
for conventional gaskets as it can fill gaps up to 0.4 mm.
Does not shrink and therefore fasteners do not need re-tightening to specified torque values
after curing.
Loctite 542
Colour: brown
Anaerobic product used a liquid sealant for threaded fittings up to 3/4” gas; rapid curing and
parts may be disassembled with ordinary tools.
Loctite 554
Colour: red
Anaerobic sealant and locking compound used for sealing cooling and industrial fluid circuits.
Slow curing, also suitable for use on non-ferrous alloys.
Loctite 572
Colour: white
Anaerobic sealant and locking compound used for sealing pipes and threaded fittings up to 2"
in diameter.
Very slow curing on most metal surfaces.
Loctite 576
Colour: brown
Anaerobic product used a liquid thread sealant for large diameter threaded fittings (up to 2").
Very slow curing; also suitable for non-ferrous alloys and parts requiring subsequent removal.
Loctite 576
Colour: green
Thixotropic anaerobic product used for sealing joints between metal faces.
Ensures total contact between surfaces with maximum tolerance of 0.10 mm, filling micro-
voids caused by flatness errors.
Very slow curing on most metal surfaces and requires prior application of an activator.
