Abstract
The expansion of Bayer's new production site at Bitterfeld is continuing apace. Just three months after federal chancellor Dr Helmut Kohl and the chairman of the Board of Management of Bayer AG Dr Manfred Schneider started up the first production plant with the symbolic press of a button, the new coating resins plant of Bayer Bitterfeld GmbH was the second project to come on stream at a recent opening ceremony. Wilhelm Held, general manager of the Coating Raw Materials and Speciality Products Business Group, explained the choice of location for the new plant in his opening address: “We chose Bitterfeld for political reasons. We want this project to be a positive symbol for eastern Germany, a symbol of reconstruction — especially in this traditional chemical manufacturing area — through the creation of modern jobs for skilled personnel. The expectation is that other investors will follow suit.”

Abstract
The ability of zinc to inhibit the rusting of steel depends on a natural phenomenon — the electrical reaction between dissimilar metals, first noted by an Italian scientist named Luigi Galvani. A French chemist discovered in 1740 that zinc could protect steel from the effects of rust. However, it would be almost 100 years before the practical problems of coating steel with zinc would be solved. In 1887 Stanislaus Sorel, a French engineer, secured a patent for hot dip galvanizing. It is basically on this method that today's techniques have been developed. Recognizing Galvani's earlier discovery, Sorel called his process Galvanization.
