Connection elements with zinc-plated chromium(VI)-free thick-film passivation (ZSML) offer a future-proof alternative compared to surfaces containing chromium(VI). The coating consists of a zinc layer with passivation on a chromium(III) basis and a sealing coat (top coat with integrated lubricating particles).



Overview of advantages:



  • Higher quality replacement for common zinc-plated coatings such as A2C or A3C

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

  • Thermal capacity up to 120°C

  • Even layer distribution

  • Functional and decorative
