Phosphating Agents, Phosphata – DEWE Brünofix
Phosphata M 5652 is a nickel-free manganese phosphating agent used to form dark grey/black manganese phosphate coatings on iron and steel and is characterized by its especially easy bath handling and its fine crystalline layers. Layer thickness, crystalline structure and density depend on the material and the prior treatment it has undergone (e.g. hardening or the like).
Phosphata Z 5650 is a low sludge zinc phosphate agent used to produce thick, fine crystalline, dark zinc phosphate layers. Depending on the material being processed, pre-rinsing or the addition of a Ferrex accelerating solution may be necessary.
