    This monograph aims to give a comprehensive and detailed review of general results, which have been obtained in a special segment of the design and manufacture of pressure-sensitive products, known as formulation. For manufacturers of pressure-sensitive products and product components, formulation probably includes the main part of their proprietary know-how. The scientific basis of formulation, explaining the reasons behind certain mixing and processing technologies, is doubtless more important than a collection of compositional data and technical parameters. This volume collects technical and scientific materials concerning the most important theoretical and practical aspects of the formulation of pressure-sensitive adhesives. Based on the author's industrial and scientific experience, this treatise constitutes a theoretical and practical state-of-the-art monograph on the formulation of pressure-sensitive products. It is a practical guide for those who want to study, manufacture or use pressure sensitive products or their components, as well as for suppliers of adhesives, elastomers, plastics and additives, or manufacturing equipment. This book will be of value and interest to production and manufacturing managers, production engineers, materials scientists, chemists and new product specialists involved in the production or application of pressure-sensitive products.
