Precote® 85

High-Strength & Heat-Resistant Thread Coating with Controlled Torque / Tension

PRECOTE® 85 are varnish-like, solvent free coating systems based on microencapsulated 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. 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.


  • High–torque performance
  • Environmental resistance to heat, automotive fluids, thermal and mechanical shock and vibrations
  • Longest shelf life in the industry
  • Complies with or exceeds major OEM specifications
  • Can be applied on external and internal threaded fasteners
