The wet strength of adhesive bonds between resins and glass or metal can be substantially improved by applying adhesion promoters to the glass or metal surface. The most widely used of these adhesion promoters are the organofunctional trialkoxysilanes (RSi(OR')3. Some of the more pertinent research results concerning these silanes have been reviewed in the hope of establishing how they function as finishing agents. Work indicates that these compounds form polysiloxane coatings on the adherend surface. These coatings consist of a strongly adsorbed polysiloxane network along with a more weakly held material consisting of small polymer molecules and unreacted silane. The polysiloxane network exposes a high density of the organofunctional group R- at the air/silane-coating interface. However, the R- groups are not closely spaced, and, in fact, there is some evidence that the coatings can be penetrated by the adhesive resin. Some new approaches are offered for research into the highly complex but exceedingly important area of adhesion promoters. (Author).

* It has been rumored that a bumble bee has such aerodynamic deficiencies that it should be incapable of flight. Fiberglass-reinforced polymer com posites, similarly, have two (apparently) insurmountable obstacles to per formance: 1) Water can hydrolyze any conceivable bond between organic and inorganic phase, and 2) Stresses across the interface during temperature cycling (resulting from a mismatch in thermal expansion coefficients) may exceed the strength of one of the phases. Organofunctional silanes are hybrid organic-inorganic compounds that are used as coupling agents across the organic-inorganic interface to help overcome these two obstacles to composite performance. One of their functions is to use the hydrolytic action of water under equilibrium condi tions to relieve thermally induced stresses across the interface. If equilib rium conditions can be maintained, the two problems act to cancel each other out. Coupling agents are defined primarily as materials that improve the practical adhesive bond of polymer to mineral. This may involve an increase in true adhesion, but it may also involve improved wetting, rheology, and other handling properties. The coupling agent may also modify the inter phase region to strengthen the organic and inorganic boundary layers.

This volume chronicles the proceedings of the Symposium on Adhesion Aspects of Polymeric Coatings held under the auspices of the Electrochemical Society in Minneapolis, MN, May 10-15, 1981. This event was cosponsored by the Dielectric and Insulation, and Electrothermics and Metallurgy Divisions. Polymeric coatings are used for a number of purposes, e. g. , decorative, protective, functional (as dielectrics or insulators) and a special application of polymeric (organic) coatings is their use as lithographic materials for making integrated circuit elements. Irrespective of the purpose of the coating, it must adhere well to the underlying substrate. So the need to under stand the factors which influence adhesion of organic coatings and the ways to attain desired adhesion is quite manifest. This Symposium was designed to bring together scientists and technologists interested in the adhesion aspects of polymeric coatings, to provide a forum for discussion of latest findings, and to provide an opportunity for cross-pollination of ideas. The technical program contained a total of 46 papers by authors from various corners of the world. The program comprised both invited overviews and contributed original research papers, as this blend is the best way to present the state of knowledge of a topic. The invited speakers were selected so as to represent widely differ ing disciplines and interests and they hailed from various aca demic and industrial research laboratories.

For several years, I have been responsible for organizing and teaching in the fall a short course on "Fundamentals of Adhesion: Theory, Practice, and Applications" at the State University of New York at New Paltz. Every spring I would try to assemble the most pertinent subjects and line up several capable lecturers for the course. However, there has always been one thing missing-an authoritative book that covers most aspects of adhesion and adhesive bonding. Such a book would be used by the participants as a main reference throughout the course and kept as a sourcebook after the course had been completed. On the other hand, this book could not be one of those "All you want to know about" volumes, simply because adhesion is an interdisciplinary and ever-growing field. For the same reason, it would be very difficult for a single individual, especially me, to undertake the task of writing such a book. Thus, I relied on the principle that one leaves the truly monumental jobs to experts, and I finally succeeded in asking several leading scientists in the field of adhesion to write separate chapters for this collection. Some chapters emphasize theoretical concepts and others experimental techniques. In the humble beginning, we planned to include only twelve chapters. However, we soon realized that such a plan would leave too much ground uncovered, and we resolved to increase the coverage. After the book had evolved into thirty chapters, we started to feel that perhaps our mission had been accomplished.
