DOS THREAD LOCK - MEDIUM STRENGTH

Screw retaining and sealing compound for the securing and
sealing of screws, bolts, nuts, threaded inserts and threaded
plugs. Restricts loosening by impact or vibration.

Provides medium strength connections.
Can be disassembled using normal tools.

Cures fast, even on stainless steel and other passive
surfaces.
No "accelerators" or "activators" required.

Outstanding resistance to chemicals and heat.
Universal product with a wide range of applications.

Shows constant friction values.
Causes uniform tension and contact pressure on assembled parts.

Prevents loosening caused by mechanical forces eg.
vibrations or impact.
No safety problems, such as in the case of traditional, mechanical screw-
locking items (spring washer, tooth washer etc.).

Fits tight and bonds firmly.
Physical Properties (in liquid state) Avoids corrosion.
