Loctite 703 Product used for degreasing and cleaning parts prior to applica -
tion of Loctite anaerobic products; after drying, promotes uniform
curing of threadlockers
Loctite 747 Product used specifically for treatment of passive metals prior to
use of slow-cure anaerobic threadlockers (series 5 and 6). Can
also be used to increase cure speed at low temperatures or in ap -
plications where there are large gaps between the parts.
sEalanTs (for
faces and fittings)
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 as 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 cool -
ing 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 573 Colour: green Thixotropic anaerobic product used for sealing joints between
metal faces. Ensures total contact between surfaces with maxi -
mum tolerance of 0.10 mm, filling microvoids caused by flatness
errors. Very slow curing on most metal surfaces and requires
prior application of an activator.
Loctite 576 Colour: brown Anaerobic product used as a liquid thread sealant for large diam -
eter threaded fittings (up to 2”). Very slow curing; also suitable for
non-ferrous alloys and parts requiring subsequent removal.

Loctite 401 Colour: colourless Cyanoacrylate instant adhesive suitable for bonding a wide range
of acidic and porous materials including, ceramics, wood, rub -
ber and plastic (excluding polyolefin). Curing takes place in a few
seconds as an effect of the condensed humidity present on the
surfaces to be bonded, and is independent of environmental con -
ditions.
Loctite 495 Colour: colourless Cyanoacrylate instant adhesive suitable for bonding a rubber,
plastics and metal in any combination.

Silastic 738 (Dow Corning) Colour: milky
white
One-part silicone adhesive/sealant, non dhrinking, ready for use.
Cures on exposure to air to form a rubbery solid and obviates the
need for conventional seals on flexible joints, filling gaps greater
than 1 mm.
Dirko Transparent Colour: transparent One-part silicone adhesive/sealant, shrinking, ready for use.
Cures rapidly when exposed to humidity in the air to form a rub -
bery solid; resistant to high temperatures.

Betaseal HV3 (Gurit Essex) Colour: black Polyurethane prepolymer based adhesive/sealant, high viscosity,
suitable for permanent, high-strength flexible bonding. Slow cur -
ing, used for bonding glass to frames, wire mesh, metal plates,
etc. surfaces must be degreased with primer.
