3M Scotch-Weld TL77 Threadlocker High-Strength Permanent Adhesive for Heavy-Duty Fasteners
3M Scotch Weld TL77 is a red high-strength permanent thread locking adhesive designed specifically for rough thread fasteners with a diameter not exceeding 38mm. Its anaerobic properties solidify under conditions that isolate air and metal ions, forming a hard adhesive layer that effectively prevents vibration, corrosion, and leakage. The typical viscosity is 7000pps, with a wide temperature range (-54 ° C to 149 ° C), an initial curing time of less than 60 minutes, and a complete curing time of 24 hours
TL77 fills thread gaps completely, delivering superior mechanical strength and sealing for high-load applications (e.g., gear housings, motor mounts). Resistant to solvents, fuels, and industrial fluids, it bonds steel, aluminum, etc. Specs: 50ml/tube, 10 tubes/box, 12-month shelf life. Post-cure shear strength reaches 22MPa, replacing mechanical washers to reduce failure risks.
Permanent Load-Bearing: Post-cure torque resistance ≥30N·m, ideal for heavy bolts in construction/ marine applications, exceeding industry impact resistance standards.
