A NEW SEALING PROCESS WITH STRONG ACIDIC AND ALKALINE CORROSION RESISTANCE

A new sealing process has been developed and is already used in industrial plants with high innovative technological content: the main feature of the technology is that it is possible to obtain an anodic oxide with good corrosion protection against alkali attack, besides the usual corrosion protection against acidic corrosion.

The sealing is similar to a cold sealing technology, very well know and approved by Qualanod and GSB for architectural use: the novelty is a special additive used in the warm (60-65°C) rinse after cold sealing. This technology has already attracted the attention of the automotive market, besides the architectural and decorative markets  since, in such markets, there are special specifications (FIAT, FORD, BMW, TOYOTA, ETC …) and special tests to measure the performance of the anodic coating against alkaline chemicals that a car  could enter in contact with during washing or in other circumstances.

The new technology (Superseal) is already used in architectural plants and plants that work for the automotive industry.
