Corrosion resistance:



  • Diameter ≥ M2 – 360h*

  • Diameter ≥ M4 – 600h*

  • Diameter ≥ M10 – 720h*


  • *No base metal corrosion at points without thread in salt spray mist testing according to DIN EN ISO 9227 NSS


Overview of advantages:



  • Corrosion resistance of up to 720 hrs to base metal corrosion in accordance with DIN EN ISO 9227 NSS

  • Chromium(VI)-free

  • Adjusted friction coefficient range of 0.09 μ–0.14 μ due to top coat with integrated lubricating particles

  • Thermal capacity up to 120°C

  • Even coat distribution

  • Functional and decorative
