Precote® 30

Medium Strength Thread Locker

Precote® 30 varnish-like, solvent free coating systems based on micro-encapsulated acrylates for sealing and locking of threaded parts. The dried film is tack-free, non-sticky and can be used in all kind of assembly procedures, particularly for series production. 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.
