ZINCROKOTE®

SIMPLIFIED TECHNOLOGY with GOOD PERFORMANCE

ZINCROKOTE® is a zinc flake anticorrosion coating using water- based chemistry. Derived from reference technologies developed by NOF METAL COATINGS, it is applied in 2 coats and meets corrosion resistance requirements up to 400 hours in salt spray test.

Coating with metallic silver appearance consisting of:

1 basecoat coat + 1 topcoat coat

Thin dry film, non-electrolytic

  • Water-based chemistry

Free from hexavalent and/or trivalent chromium, nickel and cobalt Passivated zinc and aluminum flakes in a binder

Characteristics and performance

  • Adjustable coefficient of friction thanks to PLUS-family topcoats
  • Performance maintained at elevated temperatures (up to 300C) .
  • Electrical conductivity for most application
  • Bimetallic compatibility with aluminium
  • No hydrogen embrittlement
  • Paintable coating

Corrosion resistance

  • Average thickness Salt Spray
    Test (ISO 9227)6 μm
    > 72 hours without white rust
    > 400 hours without red rust

    Results may vary depending on substrate, geometry of parts and type of application processes, without thermal shock nor mechanical damage.

Application processes

ZINCROKOTE® can be applied by Dip-Spin, using bulk or rack coating process
