LOCTITE 2400/5ML – Medium Strength Threadlock

Loctite 222/10ml – Low Strength General Purpose Threadlock

Loctite 2400 is a medium threadlocker formulated to secure and seal bolts, nuts and studs to prevent loosening due to vibration. It works on all metals and passive substrates. Slight contamination by industrial oils, corrosion prevention oils and cutting fluids is tolerated. Loctite 2400 carries no hazard symbols, risk or safety phrases and does not contain any declarable carcinogens, mutagens or reproductive toxins.

Loctite 2400 is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Particularly suitable for applications on less active substrates such as stainless steel and plated surfaces, where disassembly with hand tools is required for servicing. The thixotropic nature of Loctite 2400 reduces the migration of liquid product after application to the substrate.

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 steel nuts and bolts compared to different materials and tested according to ISO 10964.

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 steel nuts and bolts and tested according to ISO 10964.

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 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 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 ISO 10964.

Storage
Please store product in the unopened container in a dry location.
Further storage information may be indicated on the product container labeling.

Safety information
Use only in well-ventilated areas.
Gloves and safety glasses should be worn.
Prolonged or repeated skin contact should be avoided to minimise any risk of sensitisation.
Store in original containers at 8-21°C (46.4-69.8°F) and do not return residual materials to containers as contamination may
reduce the shelf life of the bulk product.
