Threadlocker Anaerobic Adhesives

Product

Description

3M™ Scotch-Weld™ Threadlocker Anaerobic Adhesives are one-component anaerobic

adhesives that cure and seal threaded assemblies that meet a wide range of applications to

prevent vibration loosening and/or leakage. All products provide excellent vibration,

corrosion, and shock resistance. Engineered to provide different strengths, temperatures,

nut/bolt sizes, and other requirements, some threadlockers allow removal and meet

various selections depending on the specific application.

Specific Features

• 3M™ Scotch-Weld™ Threadlocker TL22 is removable with hand tools. It is a low

strength (low torque removal) threadlocker for small diameter, fine threaded screws, set

screws, nuts, bolts, and hex and slot driven components such as keyed fasteners.

• 3M™ Scotch-Weld™ Threadlocker TL42 is a general purpose, removable with hand

tools, medium strength threadlocker ideal for machine tool access bolts, and hydraulic

system bolts. It can also be used on gear box/driveshaft bolts, bearing cover cap screws,

countersunk screws, and conveyor roller bolts.

• 3M™ Scotch-Weld™ Threadlocker TL43 is a general purpose, removable with hand

tools, medium strength threadlocker for most medium and coarse-threaded screws, nuts

and bolts. It is oil tolerant to help secure as-received parts and its thixotropic property

prevents run-off, dripping, or migration of the adhesive product when applied on parts.

• 3M™ Scotch-Weld™ Threadlocker TL62 is a medium to high strength threadlocker

that is especially developed to secure assemblies with high strength retention. It allows

disassembly with heat and will perform on lightly oily parts with only approximately

10% strength reduction.

• 3M™ Scotch-Weld™ Threadlocker TL71 is a general purpose, permanent, high

strength threadlocker that locks bolts and studs up to 1" in diameter as it seals against

leakage and corrosion.

• 3M™ Scotch-Weld™ Threadlocker TL72 is a permanent, high strength threadlocker

formulated to lock bolts and studs up to 1" in diameter. It can be used for high

temperature threadlocking (intermittently up to 450°F) and its thixotropic nature

prevents dripping or migration of the liquid adhesive after assembly.

• 3M™ Scotch-Weld™ Threadlocker TL77 is a permanent, high strength, high viscosity

parts.

• 3M™ Scotch-Weld™ Threadlocker TL90 is low viscosity to provide a wicking action,

medium strength threadlocker that locks and seals small compression and ferrule

fittings with service temperature up to 400°F. It is useful for pre-assembled parts.
