ADHESIVES
Loctite 401
Colour: colourless
Cyanoacrylate instant adhesive suitable for bonding a wide range of acidic and porous ma-
terials including, ceramics, wood, rubber 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 conditions.
Loctite 495
Colour: colourless
Cyanoacrylate instant adhesive suitable for bonding a rubber, plastics and metal in any com-
bination.

SEALANTS
Silastic 738
(Dow Corning)
Colour: milky white
One-part silicone adhesive/sealant, 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 rubbery solid; resistant to high
temperatures.
POLYURETHAN

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

Loctite 601
Colour:
fluorescent green
Anaerobic, fast-curing, high-strength adhesive.
Suitable for sealing and retaining cylindrical assemblies with gap clearances of up to 0.10 mm;
used for retaining rotors, gears, bearings, pulleys, bushes etc. on shafts.
Loctite 638
Colour:
fluorescent green
Anaerobic structural adhesive, quick-curing, very high strength; suitable for bonding cylin-
drical parts in non-ferrous alloys.
Loctite 648
Colour:
fluorescent green
Anaerobic structural adhesive, quick-curing, high-strength; suitable for bonding cylindrical
parts, permanent retention of threaded parts, sealing of refrigeration systems, retention of
bearings, etc.
Alternative to Loctite 601 in high-temperature applications.
Loctite 986/AVX
Colour:
fluorescent red
Anaerobic sealant/retaining compound for metal cylindrical parts.
Slow-curing, high-strength, heat-resistant and resistant to chemical pressure.
Parts must be first treated with an activator.
LUBRICANTS
Grease
(NLGI 2 EP
ASTM D217: 265/295)
Multi-purpose Lithium grease used for lubrication of seals, to prevent oxidization and to fa-
cilitate assembly operations.
Molikote
(Dow Corning)
Anti-wear compound, contains Molybdenum bisulphate, use neat or diluted with engine oil
for assembly of main engine bearings.
Vaseline
Neutral pH compound used to protect battery terminals against oxidization and corrosion.
Engine oil
10W - 30
Used to dilute Molikote anti-wear lubricant during assembly of main engine bearings.
