3M™ Scotch-Weld™ Threadlocker TL90 provides vibration, corrosion, and shock resistance for fasteners in assembled form. This green anaerobic adhesive is dispensed as a single-component, very low viscosity product. This medium removal torque anaerobic adhesive offers a long open time and cures quickly in the absence of air when parts are assembled.Our 3M Scotch-Weld Threadlocker TL90 hardens and seals threaded assemblies to resist vibration and prevent loosening or leakage of secured fasteners. Applying this adhesive to fasteners after tightening, helps seal out moisture and prevents corrosion. Application is fast and easy with just a targeted squeeze of the bottle. The anaerobic formulation begins to cure quickly into a polymer that seals, secures and retains. An activator can be used for even faster cure or larger gap sizes. This very low viscosity adhesive flows into threads after parts are assembled and loosens when needed with regular hand tools. Our 3M Scotch-Weld Threadlocker TL90 is effective for locking, vibration resistance, sealing, and bonding threaded assemblies. Places where it is useful include machine tool access bolts, hydraulic system bolts, gear box/driveshaft bolts, bearing cover cap screws, countersunk screws, and conveyor roller bolts.
