The science of environmentally friendly coatings is a very young, but rapidly growing discipline. As a result, there is a shortage of integrative information that overviews the interrelationships that exist among all the disparate sub-disciplines. This textbook provides the missing link by offering a critical overview of cutting edge, interdisciplinary technology designed to improve performance. It is the first text to describe how additives have evolved to not only take the mystery out of environmentally friendly coatings, but also to meet the challenge of the twenty-first century.
