There has been ongoing issue from Hex to Trivalent chrome conversion.

Just a few questions since I forgot the basics for coating.

Does Dacro coating always a hexavelent chrome?

What are the methods for hex to trivalenet chrome free -

Does geomet is an alternative for Hex to Trivalenet conversion?
 
Dacro coating does not always contain hexavalent chromium.

The method of converting is simple. Use trivalent starting materials instead of hexavalent starting materials.

Geomet is hexavalent chromium free, so it is a natural choice. Magni and D[ö]rken offer competing coatings with equal performance.

Cory
