INTRODUCTION
SILICON SEAL-
ANTS
Silastic 738 (Dow Corning) colour: milky
white
Single compound silicon adhesive/sealant, not settling, ready for
use. It cures into a solid rubbery consistency when it reacts with
humidity in the air and makes it possible to eliminate traditional
gaskets on elastic joints covering backlashes even greater than
a millimetre.
Dirko Transparent Colour: transparent Single compound silicon adhesive/sealant, settling, ready for
use. It cures quickly forming a rubbery solid when curing starts
due to moisture in the air and it is resistant to high temperatures.
POLYURETHANE
SEALANTS
Betaseal HV3 (Gurit Essex) Colour: Black Polyurethane prepolymer based adhesive and sealant which is
highly viscose, suitable for highly resistant permanent elastic
bonding. It cures slowly and is used for bonding glass on struc-
tures, metallic protection meshes, plates, etc., after degreasing
with a primer.
RETAINERS Loctite 601 Colour: uorescent green Fast curing anaerobic product with high mechanical resistance. It
is suitable for sealing and retaining freely moving cylindrical cou-
plings with backlash up to 0.10 mm, for fastening shafts on rotors,
gears, bearings, pulleys, bushes, main bearings, etc.
Loctite 638 Colour: uorescent green Fast curing anaerobic structural adhesive with very high me-
chanical resistance; suitable for fastening non-ferrous alloy freely
moving cylindrical couplings.
Loctite 648 Colour: uorescent green Fast curing anaerobic structural adhesive with high mechanical
resistance; suitable for retaining freely moving cylindrical cou-
plings, permanent retaining of threaded parts, sealing of cooling
systems, fastening of bearings, etc. It is an alternative product to
Loctite 601 for use at higher operating temperatures.
Loctite 986/AVX Colour: uorescent red Anaerobic sealant and retaining product for cylindrical couplings
between metallic parts. It cures slowly and offers a good mechan-
ical and temperature resistance as well as excellent resistance to
chemical pressure. It must be used after activation of the parts.
LUBRICANTS Grease (NLGI 2 EP ASTM D217: 265/295) Multi-purpose lithium grease used to lubricate gaskets, prevent
oxidation and make assembly operations easier.
Molikote (Dow Corning) Anti-wear lubricant compound, containing Molybdenum disul-
phide, used pure or diluted with a percentage of engine oil during
engine main bearing assembly phases.
Vaseline Neutral PH compound used to protect the poles and terminals of
batteries from oxidation and corrosion.
10W - 30 engine oil Used to dilute Molikote anti-wear lubricant during engine assem-
bly phases.
