Connection elements with a galvanised chrome (VI)-free zinc-nickel coating (ZSML) offer a more future-proof alternative compared to surfaces containing chrome(VI). The coating consists of a zinc layer with passivation on a (chrome III) basis and sealing coat (top coat with integrated lubricating particles).
Overview of advantages:
- Higher quality replacement of common galvanised 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
