Description

3MTM Scotch-WeldTM 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

 3MTM Scotch-WeldTM 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.

 3MTM Scotch-WeldTM 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.

 3MTM Scotch-WeldTM 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.

 3MTM Scotch-WeldTM 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

 3MTM Scotch-WeldTM Threadlocker TL70 is a high strength threadlocker

that locks all metal fasteners and thus prevent vibration loosening and leakage

through the applications where maximum strength is needed. TL70 prevents

corrosion of assembled parts.

 3MTM Scotch-WeldTM 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. Temperature resistance intermittently up

to 400oF.

 3MTM Scotch-WeldTM Threadlocker TL72 is a permanent high strength

threadlocker to locks bolts and studs up to 1” in diameter. It can be used for

high temperature threadlocking (intermittently up to 400oF) and its thixotropic

nature prevents dripping or migration of the liquid adhesive after assembly.
