Thread locking fluid or a threadlocker was developed in 1953. A threadlocker is a single component adhesive (non-reactive adhesive) and is thin with respect to the viscosity. A very strong alternative to mechanical locking devices, it finds its use in fasteners, which are devices used to affix two objects together, and is applied to its threads; screws and bolts are typical example of fasteners where threadlocker is applied to prevent leakage, loosening and corrosion. Most of the threadlockers are methacrylate which depend on the electrochemical activity of the metal substance which causes the fluid to polymerize. The fluid used in the threadlocker is thixotropic. This thinning property, which is time dependant, allows it to flow easily and at the same time resist the vibrations and shocks. This can be permanent or it can be removed with the application of heat. Depending on the type of work, the threadlocker can be applied either before or even after the assembly. The permanent, heav...
