PRODUCT DESCRIPTION
LOCTITE

Product 5923 is a dark reddish brown, viscous liquid
with a characteristic alcoholic odour. It is a slow drying liquid
that changes to a pliable, tacky film through solvent
evaporation. It seals close fitting parts, machined surfaces and
threaded connections in industrial, aircraft, and marine
applications.
PRODUCT BENEFITS
• For close tolerance flanges
• Slow drying
• Flexible setting
TYPICAL APPLICATIONS
• Solid gasket dressing
• Close fitting machined surfaces
• Threaded connections
• Aviation engines
• Marine engines
DIRECTIONS FOR USE
1. Remove all previous material from mating surfaces.
2. For best results, clean and dry all surfaces with a
residue-free solvent.
3. Remove cap. Coat with brush-top applicator.
4. When used as a gasket dressing, spread product with
a spatula to a uniform film on one side of gasket and
then position it on the assembly. Coat the second side
of gasket and re-assemble. Slower drying formula
increases work time.
5. Assembly is operational after 4 hours, full cure is
effective after 24 hours.
For Cleanup
1. The product can be removed from metal surfaces with
isopropyl alcohol. If the sealant has been dried for a
long time or at high temperatures, cover the sealant
with alcohol and allow to soften overnight.
2. Clean hands with hand cleaners.
