Aluminium Conversion Coatings

Housing for the communication technology, pickled and yellow conversion coated

This process concerns about a replacement fort the transparent resp. yellow chromating. For constriction of the assignment of certain hazardous matters in electro- and electronical devices the European Parliament has decided in its guideline 2002/95 EG and in the addition of 27.01.2003, that chrome- and chrome VI-containing protective coatings must not be implemented for this anymore.

The new invented protective coatings, listed aside assure an excellent corrosion protection and a very good wash primer for a subsequent coating.

Depending on the aluminium alloy, glossy and matte coatings will be reached, because in particular, latter are more grip-sensitive as chromated coating, the use of gloves at further processes is recommended.
