3 Scotch-WeldTM Threadlocker Anaerobic Adhesives TL22 * TL42 * TL43 * TL62 * TL71 * TL72 * TL77 * TL90 Technical Data March, 2010 Product 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 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. * 3MTM Scotch-WeldTM 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 450F) and its thixotropic nature prevents dripping or migration of the liquid adhesive after assembly. * 3MTM Scotch-WeldTM Threadlocker TL77 is a permanent, high strength, high viscosity threadlocker designed to work well with larger diameter (up to 11/2") and coarse threaded parts. * 3MTM Scotch-WeldTM 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 400F. It is useful for pre-assembled 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 (approximately 490F) 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. Material Surface Activity and Cure Speed Active (Fast) * * * * * * * * * Brass Bronze Commercial aluminum Copper Iron Kovar(R) Manganese Monel(R) Nickel -3- * * * * * * * * * * * * * Inactive (Slow) Anodized aluminum Cadmium Chemical black oxide Galvanized steel Gold Inconel(R) Magnesium Magnetite steel Plated parts Pure aluminum Silver Stainless steel Zinc 3MTM Scotch-WeldTM Threadlocker Anaerobic Adhesives TL22 * TL42 * TL43 * TL62 * TL71 * TL72 * TL77 * TL90 Military Specification S-46163A 3MTM Scotch-WeldTM Threadlocker Anaerobic Adhesives TL22, TL42, TL62, TL71, TL72, TL77, and TL90 have been tested and passed the requirements of MIL-S-46163A.
