Nonpolluting Coatings and Coating Processes: Proceedings of an ACS Symposium Held August 30-31, 1972, in New York City - Tapa dura

Reseña del editor

Ecological requirements are forcing a change in tech­ nology of industrially applied coatings. At present sol­ vent-borne coatings dominate this field but in the next few years rapidly increasing use will be made of aqueous coatings, electrocoating, solvent-free liquid coatings which can be cured by U. V.-light or electronbeam, and powder coatings. This monograph describes some recent developments in these new "non-polluting" coating technologies. It is impossible to predict how big a share each of these novel coatings will take from the conventional in­ dustrial finishes market which at present represents an annual volume of about one billion dollars. In all likeli­ hood each will find its own specialized use. We hope that this monograph will help the reader to form a perspective of the various novel coatings, their method of application, their advantages and their limitations. J. L. Gardon Joseph W.
