Heavy metal scrapped
By Alex Dahm08 May 2008
The European Union environmental policy forbids the use, in all production processes, of heavy metals, such as lead, mercury, cadmium and hexavalent chromium (Cr VI).
In response, Olmark in Italy, has come up with its Platinum treatment, which consists of a passivation process (zinc coating) that is chromium trivalent-based, rather than Cr VI, for protecting its hydraulic components against corrosion.
According to Olmark, its technical staff conducted demanding tests to guarantee that the elimination of Cr VI from coating processes does not prohibit some of its products, such as crimped fittings, adapters and bent rigid pipes, from undergoing the treatment.
