Loctite 272/50ml – High Strength Threadlock

Loctite 275 high strength, high viscosity, large threads threadlocker.

Loctite 275 is designed for the permanent locking and sealing of threaded fasteners. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Typical applications include the locking and sealing of large bolts and studs (M25 and larger).

Typical Curing Performance

Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph shown in the data sheet shows the breakaway strength developed with time on M10 black oxide nuts and bolts compared to different materials and tested according to MIL-S-46163.

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. Gaps in threaded fasteners depends on thread type, quality and size. The graph shown in the data sheet shows shear strength developed with time on steel pins and collars at different controlled gaps and tested according to MIL-R-46082.

Cure Speed vs. Temperature
The rate of cure will depend on the temperature. The graph shown in the data sheet shows the breakaway strength developed with time at different temperatures on M10 black oxide nuts and bolts and tested according to MIL-S-46163.

Cure Speed vs. Activator
Where cure speed is unacceptably long, or large gaps are present, applying activator to the surface will improve cure speed. The graph shown in the data sheet shows the breakaway strength developed with time on M10 zinc dichromate steel nuts and bolts using Activator 7471 and 7649 and tested according to MIL-S-46163.
