case, it can be removed with heat, for example. Typically, brands are color-coded to indicate strength and whether they can be removed.
History.
Thread-locking fluid was developed by American professor Vernon K. Krieble in 1953. His company, American Sealants, founded the Loctite brand. An early version of the compound was patented in 1960.
Properties.
Typically, thread-locking fluids are methacrylate-based, and cure anaerobically. Thread-locking fluid is a thixotropic fluid: under shear
Thread-locking fluid
Thread-locking fluid or threadlocker is a thin, single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion.
Most thread-locking formulas are methacrylate-based and rely on the electrochemical activity of a metal substrate to cause polymerization of the fluid. Thread-locking fluid is thixotropic, which allows it to flow well over time, yet still resist shocks and vibrations. It can be permanent or removable; in the latter
