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.

Threadlocker Anaerobic Adhesives TL22 • TL42 • TL43 • TL62 • TL70 • TL71 • TL72 • TL77 • TL90 Handling Information Directions for Use: 3MTM Scotch-WeldTM Threadlocker Anaerobic Adhesives are not recommended for use on most plastics due to potential cracking of plastic parts. Also, they are not recommended for use in piping systems that contain pure oxygen or an oxygen-rich environment, chlorine, or strong oxidizing substances. For Assembly: 1. Ensure parts are clean, dry and free from oil, grease and dirt. For best results, clean and dry parts with solvent or 3MTM Scotch-WeldTM Activator. (Activator can also be used on inactive surfaces or to accelerate the cure on active surfaces.) 2. If not sure of surface type, always use activator. Refer to Material surface Activity and Cure Speed section for more information. 3. Shake the adhesive bottle well before use. 4. Avoid touching the metal surfaces with the bottle tip since the metal ions may react with the adhesive upon contact and eventually may clog the bottle tip. 5. Apply adhesive onto the threaded part where the contact area will be in the final assembly. For larger parts, use more adhesive and rotate the threaded part to spread adhesive evenly around contact area. 6. For through holes, apply several drops of adhesive onto the bolt at the nut engagement area. For blind holes, apply several drops of the adhesive down the internal threads to the bottom of the hole. 7. Assemble the nut / fastener and tighten as required. 8. Allow assemblies to set for sufficient time so that handling strength or full cure will occur before further processing or testing For Disassembly: 1. Loosen or remove with regular hand tools. 2. If hand tools do not work due to the assembled parts being well tightened, apply localized heat (approx.. 400oF / 254oC) to the nut or bolt and disassemble while parts are still hot. Use extreme caution when working with heat sources (e.g. heat gun, flames, etc.)
