Chrome free pre-treatment
Permanently corrosion-protected with chrome free pretreatment for aluminum - Nabutan 310
With Nabutan 310 pre-treated profiles after 10 years without corrosion. This shows an outsourcing of test panels in Florida, USA.
In the year 1998, the chrome free pre-treatment of metals was largely unknown. At that time NABU-Oberflächentechnik GmbH was one of the first companies, which introduced this technology into the German market.
At the beginning, there was great distrust, because there were no knowledge of long-term effects. Now it shows that the NABU-Oberflächentechnik GmbH was right with their assessment. Profiles pre-treated with Nabutan 310, which where outsourced 1998 in Florida show no significant signs of corrosion even after 10 years. Under the extreme conditions of Florida, where the profiles are exposed intense sun and aggressive sea air, the reliability of the Nabutan system proves itself. The GSB-approved product Nabutan 310 combines the long-term corrosion protection of conventional chromating with the specific advantages of a chromium-free pre-treatment: classification only as irritant and thus advantages during storage and handling; Use in the No Rinse process and therefore, hardly any rinse water; significantly lower disposal costs.
As one of the pioneers in the field of chrome free pretreatment, NABU-Oberflächentechnik GmbH has acquired extensive knowledge over the years. Even difficult processes run today without chromium. With its wide experience, NABU advises customers on the entire pretreatment process. From the introduction of chrome-free processes to continuous optimization of the processes, NABU technicians are always at the customer's side.
The success of the chromium-free system motivates the NABU-Oberflächentechnik GmbH to develop further this technology. Besides the approved Nabutan 310, there is now a whole family of chrome free products. The Nabutan series enables the use of environmentally friendly and economical technology in the pretreatment of various metal surfaces.
Chromium-free processes combine corrosion protection and environmental protection. Moreover, the long-term test of Nabutan 310 proves once again: to pretreat chrome free means to act sustainably!
