VDM Metals adopts Henkel’s nitric acid-free pickling process


VDM Metals Group, a German manufacturer of nickel alloys and special stainless steels, has adopted Henkel’s nitric acid (HNO3) free Bonderite C-CP (“Cleanox”) pickling process for dedicated wire products. The Bonderite C-CP product range answers market requirements within the metals industry to significantly increase the sustainability value of their production processes, said Henkel. The Cleanox technology has already been in use in multiple industries globally, and is said to be suitable for all stainless steel grades and can be used in multiple applications. VDM Metals is using Henkel’s Cleanox technology to pickle rolled wire of high-alloyed materials in order to ensure the compliance with NOx limits.

“Customers such as VDM Metals have been benefiting from competitive production costs, whilst realising a significant contribution to both ecological improvement and production safety. Together with our chemical and electric pickling, paired with our equipment to automatically control and dose chemicals, we are able to offer a systematic package to customers who are focused on increasing their sustainability,” said Bjoern Lorenz, Sales Manager Metal Coil at Henkel for Western Europe.

There are challenges around common mixed acid pickling systems, due to the use of nitric acid. Henkel´s Bonderite C-CP overcomes various environmental and cost hurdles with the latest in its line of nitric acid-free cleaning technologies, as per the press statement. “Our adoption of Bonderite C-CP has allowed us to optimise the pickling process. Henkel´s advice on how to manage the process and optimise the consumption was the base of the flawless change from mixed acids to the Bonderite technology. The problem of nitrate loads has been clearly mitigated. Meanwhile the process works without any problem, the new pickling procedure is well established,” said Olaf Kazmierski, SVP of Production at VDM Metals.

The latest innovation in the Cleanox range is the deployment of acid recovery acid machines that make the technology even more cost effective and sustainable. This equipment is offered by Henkel to fulfill multiple purposes, but primarily to further reduce any sludge remaining in the production system, as well as for the recycling of used Bonderite C-CP products, according to the press release.
