Preface A basic industrial process is the bonding of alike and different materials to each other. Adhesion using an adhesive has proven to be an effective means of material bonding. This book describes treatment methods that must be applied to a material surface before successful adhesive bonding is possible. There are numerous examples ranging from wallpaper in a house and paint on surfaces, to parts used in the construction of aircraft. The aim of this text is to explain, in a simple yet complete manner, all that is required to achieve successful adhesion bonding of different mate- rials. Fundamental material considerations have been given priority to enable the use of the contents of this book in different industries. The book is both a reference and a source for learning the basics, and is useful for all involved in the product value chains. The book also offers information helpful to engineers, chemists, students, and all others involved in material adhesion and processing. This book is intended to be a handbook for reference of processes and techniques, but it is written with a technical tone. This approach increases the availability of the whole text to readers with a college level background in mathematics and chemistry, but an in-depth knowledge of adhesion technology is not necessary. Chapters 6 through 8 can be used by almost anyone interested in surface treatment of materials and does not require college level background. The book is organized in two parts. The first five chapters discuss definitions, surface characterization and analysis, surface energy measure- ment methods, adhesion mechanisms, and failure modes. Chapters 6 through 8 provide extensive information about surface treatment of materials. Chapter 6 is focused on surface preparation and treatment of metals and plastics to render surfaces bondable and to enhance the strength and durability of the bond. This chapter also includes the surface treatment XIV SURFACE TREATMENT OF MATERIALS FOR ADHESION BONDING techniques for fluorinated polymers, which are resistant to most techniques. Chapter 7 reviews the techniques applied to specific metals to make them bondable. Chapter 8 describes the surface preparation methods for plastic, thermosetting, and elastomeric materials. Some of the materials in chapters 7 and 8 are updated from the excellent reference and classic Noyes publication, Adhesives Technology Handbook, by Arthur H. Landrock (1985), now out of print. Attempt has been made throughout the text to balance the practical with the theoretical. Every chapter has been arranged so that it can be studied independently. For those who are interested in in-depth information, content and references have been provided for surface, adhesion, and polymer science in chapters 1 through 5. The reader interested only in the practical information can directly consult chapters 6 through 8. The references listed at the end of each chapter serve as both a bibliography and source for additional reading. Review papers are helpful as a starting point for finding additional sources for concentrated reading in a selected area. The sole purpose of surface treatment in the present context is to render surfaces adherable. It is virtually impossible to understand or achieve adequate surface preparation and treatment without an intimate knowledge of the science and practice of adhesion.

A note indicating the specific error to the publisher, for the purpose of correction of future editions, would be much appreciated. Sina Ebnesajjad 2006 Cyrus F. Ebnesajjad Acknowledgments No massive undertaking can be completed without the contributions of many people and organizations. Many companies and individuals have contributed information and data to this book. The authors are grateful to each company and individual for their contributions. Diligent attempts have been made to acknowledge every contributor. Any oversight errors brought to the attention of the publisher or the authors will be corrected in future editions. We would like to especially thank our friend, Dr. Laurence W. McKeen, for the in-depth review of the manuscript, suggestions, corrections, and contribution of the section on the grit blasting of metals. We are indebted to Larry for his friendship and care. Credit goes to Arthur H. Landrock for the materials updated (found in Chs. 7 and 8 of this book) from his excellent Adhesives Technology Handbook (Noyes Publications, 1985), now out of print. We would like to thank Mr. Bill Woishnis and Mr. Martin Scrivener of William Andrew Publishing for their support of the authors in this en- deavor. It would have been virtually impossible for us to complete this project without the editorial and production support of Brent Beckley (thank you for the cover design), Valerie Haynes, Betty Leahy, and Millicent Treloar at William Andrew Publishing. Our sincere thanks go to Ms. Jeanne Roussel and her staff at Write One for converting the raw manuscript into a real book with endless care and patience. We thank Jeanne for attending to the details in this manuscript. The authors wish to thank the staff of the Information and Computation Technology group at the DuPont Company for their support in literature search and securing references. We are most appreciative of Ms. Olga Grushin and her staff, our friend Tom Johns, Debbie Hale, Rita Fisk, XVI SURFACE TREATMENT OF MATERIALS FOR ADHESION BONDING Carmela Brown, Debbie Martin, Cathy Brown, Shirley Olson, and Doreen Berling at the Lavoisiers Library for all their support. We would like to especially thank our copy editor Jessica Brooks (at the time a student at DePaul University) for her many excellent suggestions, corrections, and upgrades. Finally, there are not enough words for Sina to thank his friend and soulmate, Ms. Ghazale Dastghaib, for her unconditional support and encouragement throughout this project.
