Details

3M™ Scotch-Weld™ Threadlocker TL77 provides vibration, corrosion and shock resistance for fasteners in assembled form. Our red, high removal torque anaerobic adhesive is dispensed as a one-component, medium viscosity product. This long open time anaerobic adhesive cures quickly in the absence of air when parts are assembled.

Prevents Nuts and Bolts from Loosening with Vibration
Our 3M™ Scotch-Weld™ Threadlocker TL77 hardens and seals threaded assemblies to resist vibration and prevent loosening or leakage of secured fasteners. Applying this adhesive to fasteners before tightening seals out moisture and prevents corrosion. Application is fast and easy with just a targeted squeeze of the bottle. Engineered for use on larger bolt sizes and coarse threaded parts, 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. The high strength adhesive is only removable through high heat application.

Recommended Applications

  • Threadlocking of larger screws, bolts and nuts, and coarse threaded parts
  • Applications vary by temperature resistance, removability and oil tolerance

Eliminates the Need for Lock Washers and Other Locking Components
Our 3M™ Scotch-Weld™ Threadlocker TL77 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.

Understanding Anaerobic Adhesives
Anaerobic adhesives are uniquely formulated to cure in the absence of oxygen. The term "anaerobic" means "living without air" and when the oxygen is excluded, a chemical chain reaction begins that causes the adhesive to polymerize. Contact with metal speeds the polymerization process and rapidly accelerates the curing process, forming tough
