New zinc phosphating with improved corrosion protection

NABU established a new zinc phosphating process. The new innovative product Nabuphor 121 replaces the previous product Nabuphor 119. The modified system does not contain any nitrates and can be used with two different accelerators depending on the application. The new zinc phosphating is characterized by low zinc content. Firstly the resources will be saved and secondly the corrosion resistance will be improved sustainable. At the moment there will be reached a corrosion resistance of 750 hours in combination with a powder coating on steel with a delamination of < 3mm (DIN EN ISO 9227). There are no adaptions on the plant necessary for the usage of Nabupor 121.
