ThrEad loCk Loctite 222 Colour: opaque fluorescent
purple
Anaerobic product suitable for weak thread locking of set, adjust-
ing and precision screws and nuts. It must be used after having
removed all traces of lubricant with a specific activator.
Loctite 242 Colour: fluorescent blue Anaerobic product suitable for preventing loosening of all types
of screws and nuts and to replace mechanical locks. Used for
medium resistance thread locking. It must be used after having
removed all traces of lubricant with a specific activator.
Loctite 243 Colour: opaque fluorescent
blue
Alternative product to 242 which, since it is oil compatible, it does
not require the activation of slightly lubricated surfaces.
Loctite 270 Colour: fluorescent green Anaerobic product for extra strength locking of threaded parts,
bolts and stud bolts which normally do not need to be removed.
Removal of parts may require heating to around 80°C. It must be
used after having removed all traces of lubricant with a specific
activator.
dEgrEasIng
agEnTs and aC-
TIVaTors
Loctite 703 Product for degreasing and cleaning parts before application of
Loctite anaerobic products; after it is allowed to dry, thread locks
will cure uniformly
Loctite 747 Specific product for treatment of surfaces not very active towards
anaerobic products with slow curing (series 5 and 6). It can also
be used to accelerate curing in low temperatures or if there is a
lot of backlash between parts.
sEalanTs (for
surfaces and
unions)
Loctite 510 Colour: Red Very fast anaerobic product suitable for sealing between metallic
surfaces, can be used to eliminate traditional gaskets, since it can
fills gaps up to 0.4 mm. Since it does not settle, the torque does
not need to be reset.
Loctite 542 Colour: Brown Anaerobic product used as a liquid gasket for sealing threaded
unions with a measurement under 3/4” gas; it cures quickly and
the parts can be disassembled with normal tools.
Loctite 554 Colour: Red Anaerobic sealant and locking product used to seal cooling and
industrial fluid circuits. It cures slowly and is also suitable for use
on non-ferrous alloys
Loctite 572 Colour: White Anaerobic sealant and locking product used to seal pipes and
threaded unions up to a diameter of 2”. It cures very slowly on
most metallic surfaces.
Loctite 573 Colour: green Thixotropic anaerobic product suitable for sealing metal surfaces.
It ensures total contact between the surfaces with a maximum
backlash of 0.10 mm even filling microspaces due to planarity
imperfections. It cures very slowly on most metallic surfaces and
requires the use of an activator.
Loctite 576 Colour: brown Anaerobic product used as a liquid gasket for sealing large di-
mension threaded unions (up to 2”). It cures very slowly and is
also suitable for non-ferrous alloys and parts which require later
removal.
InsTanT adhE-
sIVEs
Loctite 401 Colour: colourless Instant cyanoacrylate adhesive suitable for bonding acid and
porous surfaces of a wide range of materials including ceramic,
wood, rubber and plastic (with the exception of polyolefins). It
cures in just a few seconds due to the effect of the atmospheric
humidity on the surfaces to bond, regardless of the ambient con-
ditions.
Loctite 495 Colour: colourless Instant cyanoacrylate adhesive suitable for bonding rubber and
plastics even in different combinations, including metals.
