Composition, Printing and Bookbinding: Graphischer Betrieb. Konrad Triltsch. D-97070 Wurzhurg Printed in the Federal Republic of Germany Preface to the Second Edition The work at hand offers a wealth of information about coating materials and coating processes in a form that is clearly laid out. The swift pace of developments in the past few years has made a revised edition seem appropriate. The organization and structure of the work have been maintained, but changes and additions to content have been made where necessary. In particular, attention has been paid to updating economic data and information on standards, laws, and regulations. Com- mercially available products and their producers have also been subject to clearly recognizable changes, and these changes have been in part caused by the growing tendency of companies to merge and concentrate on their core businesses. Among products and processes, the trend to environmentally friendly alternatives has also increased, even though the share of solvent-containing coating materials still dominates the market. Therefore, the article on solvents will remain indispensable for some time to come. The second edition will serve to confirm the book in its role as a standard reference for anyone working with coatings. Marl, April 1998 WERNER FRE~TAC Preface to the 1st edition Paints and coatings are used to protect substrates against mechanical, chemical, and atmospheric influences. At the same time, they serve to decorate and color buildings, industrial plants, and utensils. Coatings are of high economic importance because they provide protection against corrosive and atmospheric attack. It is therefore understandable that in industrialized countries such as the European Community, the United States, and Japan the annual consumption per capita is high and is continuing to rise. There are numerous paint systems, production and process technologies due to the many demands made on quality, processibility, and economical importance. These have been fully discussed in this book, which presents the articles “Paints and Coatings” and “Solvents” as published in the 5th Edition of Ullmann’s Encyclope- dia of Industrial Chemistry. Comprehensive information on all paint systems and binders, pigments, tillers, and additives has been given in individual chapters. Modern, low-emission paints such as high-solids paints, water-borne paints, powder paints, and radiation-curing systems are also discussed in detail. There are special sections which deal with different production and processing technologies. Recommendations for each target application of a coating system are provided. Finally, special treatment of state-of-the-art paint testing, analysis, envi- ronmental protection, recycling, and toxicology is offered. Although the paint industry has made great efforts to substitute volatile and organic solvents for environmental reasons, the majority of paints today still contain these solvents since they are useful processing agents. A knowledge of their physical data, their toxicological and environmental properties as well as the interaction between solvent and binder forms the basis for practice-oriented paint development. The inclusion of the chapter on Solvents is an ideal addition to this presentation of coating systems. The special value of this book is that it provides a concise, up-to-date overview of all the properties of paints and coatings, their production and processing technolo- gies, and applications for a wide readership. The book is generously illustrated with numerous figures that aid further understanding, and the extensive literature refer- ences serve to deepen one’s knowledge of the topics described. The publisher has successfully gathered together authors of international renown. Undoubtedly, the book will become a standard work for all producers of raw materials, paints and coatings, for users of paints and coatings, as well as for institutes and public authorities.
