Precote® 85

Precote® 85 are 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. 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.

 

Advantages
  • Curing begins in about 10 minutes with full locking in 8 hours
  • Controlled friction to improve joint tension
  • Epoxy chemistry for robust structural bonding performance
  • High–torque performance
  • Environmental resistance to heat, automotive fluids, thermal and mechanical shock and vibrations
  • Bonds to a broad range of fastener finishes
  • Longest shelf life in the industry
  • Complies with or exceeds major OEM specifications
  • Seals against pressures up to 400 bar (5760psi)
  • Parts are ready for assembly
  • Precise thread coverage in every part
  • Can be applied on external and internal threaded fasteners
  • Is not affected by high humidity conditions
  • Dry-to-touch and tack free with good adherence
Technical Data
  • Color — turquoise (special colors available upon request)
  • Thread Friction Value > 0.10 – 0.15
  • Curing Time (RT) 8 hours (an additive of “-3” will reduce to 2 hours)
  • Temperature Range: -50°C (-58°F) to +170°C (+338°F)
  • Shelf-Life 4 years at room temperature
  • For small thread crest (less than 1 mm an additive of “-8” can be added to increased performance)
Performance Results
