Outsourcing: the project offers a solution to the galvanic industry community regarding a European problem. 80% of all metal platers utilize one or more passivating (the last process step in the galvanic line) bath during their daily production. E.g.: in the whole of Europe the production of large low quality galvanized products has decreased enormously, due to the competition of the low wages countries. Therefore technological advance leading to an innovative minded galvanic industry, producing high quality products for industrial sectors within Europe, will assure the continuation of the metal plating industry. The R&D and implementation of EPT is the first most essential step, toward this development. As there are many different new Cr(VI) free passivating liquids, being developed and produced by many chemical suppliers, the compositions of which are different from each other, only a European approach can be successful. The knowledge base and economics of the metal plating community are not strong enough to perform and/or to finance this RTD effort.

The scientific objectivesare: • Develop a modeling theory for mass transfer in the EP process and identify rate limiting steps. The mass transfer for the tramp ions Fe3+ and Zn2+ is targeted as 150 mg/h and 4g/h per standard membrane module with 19.6 m2 membrane area. • Determine the mechanisms of extraction, regeneration and selectivity of extractants for existing passivating baths and newly developed Cr(VI) free baths, Zirconium and other Cr(VI) replacements, based baths. The selectivity for Fe3+ and Zn2+ is targeted a factor 100 higher then for Cr3+. • Establish the top 3 parameters determining the mechanisms influencing product quality. • The technological objectivesfor the EPT technology and methodology are: • Extend the life time of passivating bath and new Cr (VI) free passivating bath liquids from now being 6 – 12 weeks with a factor 10, resulting in a decrease of operational costs. • Reduce the current waste quantities from spent passivating baths, by 90%, resulting in a contribution to preservation of the environment. • Improve product quality of the passivating operation by reducing off spec products in terms of insufficient corrosion resistance by 90%, leading to a competitive advantage on the world market. • The target price of EPT unit, for an average SME, is around € 45,000 to € 60,000. • Economical feasible process with a pay back time of less then 1 year.
The Consortium • In this project the AGs have connected 4 RTDs with their specific knowledge of EPT technology and plating technologies, a specialized equipment designer and manufacturer and several SME metal plating shops, which apply different types of passivating baths. The technological specifications for EPT will be developed by the RTDs. According to these specs seven pilot installations will be built and demonstrated at the sites of the SMEs. Details for optimization, especially based on feed-back of results by the SMEs, will be supplied to the equipment manufacturer and the SMEs by the RTDs. The AGs will facilitate the RTD ↔ SME actions and discussions. The benefits of EPT will be demonstrated for all passivating operations, and the project results will be transferred to other AGs and SMEs in Europe. .
