  • Good basis for paint

Chromate Conversion coating is a type of conversion coating used to passivate aluminium alloys.
It is primarily used as a corrosion inhibitor, primer, decorative finish, or to retain electrical conductivity

  • Surtec 650 - is a hexavalent chromium free passivation for aluminium, suitable for alloyed and cast aluminium. It is also used as a pretreatment before lacquering, powder coating and gluing. Electrically it has a low contact resistance and good electrical conductivity.

We offer

  • Flexible solution across multiple geometries
