Loctite 2701/250ml – High Strength Threadlock
Loctite 2701 High strength, especially for chromated surfaces Threadlocker.
Loctite 2701 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. This product is particularly suited for use on inactive substrates and/or where maximum resistance to hot oil is required.
Chemical Type: Dimethacrylate ester
Appearance (uncured): Green liquid
Fluorescence: Positive under UV light
Components: One component: Requires no mixing
Secondary Cure: Activator
Typical Curing Performance
Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph below shows the shear strength developed with time on steel pins and collars compared to different materials and tested according to ISO 10123.
Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. The following graph shows shear strength developed with time on steel pins and collars at different controlled gaps and tested according to ISO 10123.
Cure Speed vs. Temperature
The rate of cure will depend on the temperature. The graph below shows the shear strength developed with time at different temperatures on steel pins and collars and tested according to ISO 10123
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 below shows the shear strength developed with time on zinc dichromate steel pins and collars using and tested according to ISO 10123.
