Eco-friendly Conversion Coatings

BONDERITE® Chrome-VI Free Technologies

Reduced environmental impact – improved health, safety and efficiency.

An upcoming EU-guideline, no longer allowing the use of Chrome-VI for corrosion protection of metals (except for safety-critical applications like aerospace) requires new alternatives to replace Chrome-VI coated components while maintaining the properties.

Conforming to the EU directives for conversion coating processes for light metal substrates by offering health and safety and process costs advantages.

BONDERITE conversion coatings produce a homogeneous conversion layer with excellent corrosion resistance properties and paint adhesion characteristics. By avoiding Chrome-VI decontamination as well as the use of less water and energy, the total process costs get lower and the process itself more eco-friendly.

Compared to Chrome-VI processes health impact is reduced. Currently Chrome-III and non-chrome pretreatment technologies are already conform to REACH (obligatory September, 2017).

Henkel assists customers closely during the conversion from a Chrome-VI process to the sustainable alternative, including recommendations on the chemical cleaning of the production line. The process can be monitored using special dosing and control equipment like BONDERITE Lineguard Supervisor.
