Using Loctite® Adhesive
The proper use of Loctite® retaining compounds during service is essential to
enable certain fasteners to be correctly retained.
The Loctite® adhesive/sealant retaining compounds, are anaerobic, single-
component resins supplied as a liquid. These resins remain in a liquid state in
the presence of air, but harden into insoluble plastic film solids when confined
between clean, close-fitting metal surfaces. They can be used in conjunction
with natural rubber, glass, ceramics, and thermosetting plastic surfaces, such as
phenolic and polyester. Also, they do not usually harm nylon, polyethylene, or
saran. However, in their liquid state, they sometimes soften or craze vinyl,
cellulosic, styrene, methacrylate plastic, such as Plexiglas®, and varnished
finishes. Cured resins do not affect any of these materials. It is important to
note that an opened bottle of these products has a definite shelf-life of about 6
months, which affects its serviceability.
The resins referred to within this manual usually cure to their hardened state on
metal parts without need of primers. However, the use of a recommended
primer will help degrease the part and leave a light deposit of a catalyst to
speed curing. The temperature of the parts also affects their cure time. At 40F
(4C) it may take weeks to cure, but at 75F (24C), parts cure within the
time length indicated on the bottle.
WARNING:
Use primers with adequate ventilation. Avoid skin contact and
prolonged or repeated breathing of vapors. Do not allow primers to be
trapped under rings, watch bands, etc. Observe all directions on the
primer can. Failure to do so could result in personal injury.
When using the product recommended during the service procedure:
1. Disassemble the parts, remove the old Loctite®, and clean the parts.
Reapply the new Loctite® during reassembly.
2. Apply to clean surfaces only. If necessary, degrease the parts.
3. Use liquid sparingly (usually one or two drops on threaded fasteners).
Be sure to apply where thread engagement begins.
4. Assemble the parts and allow them to cure. Observe the time stated on
bottle label before placing back into service.
