What is PRECOTE 80? A locking product
Precote 80 is varnish-like, solvent-free coating systems based on microencapsulated acrylates for sealing and locking of threaded parts. The dried film is tack-free and non-sticky. Its characteristics as a locking and sealing element become effective only when the capsules are ruptured by shear and pressure stress and the adhesive is allowed to cure.

Application of PRECOTE 80 to fasteners
Precote 80 is a high-strength thread-locking product with a locking effect even at high temperatures. It can be used on all types of external and internal threads.
The coating can be used in all kind of assembly procedures, particularly for serial production.
Areas of application are electronics, two wheel and automotive industry, household appliances, office machines, computer industry, electric motors, e-mobility, etc.
