Since UV curing (light induced polymerisation of multifunctional oligomers) is a very ecoefficient and energy saving curing method, the growth rates of UV curable coatings are in the range of 10% per year. The typical UV coatings are solvent free (100% solids), thus helping the industry and the environment to reduce significantly VOC (volatile organic compounds). Recently, the automotive industry has discovered that UV cured coatings are very scratch resistant, which stimulated very extensive work into the development of UV coatings for automotive applications. Since UV curing is very universal, also other systems besides the 100% solid (typical) UV coatings are developed, like waterbased UV- , UV powder and Dual cure (UV and thermal) systems. UV Coatings contains an overview of the technology, the curing process including the equipment necessary, the raw materials (resins, diluents, photoinitiators) used, the advantages and drawbacks of this fast emerging technology, as well as proposed technical solutions to tackle the disadvantages. Structure-property relationships will be given, especially regarding the mechanical properties of coatings as well as scratch resistance, mainly dealing with automotive performance criteria. The main part of the book will deal with new developments, like water-based UV coatings, UV powder coatings and dual cure systems, cured by UV and thermal energy, which have been developed to cure the coating on three dimensional substrates in shadow areas. The main applications of UV Coatings will be described, starting with the classical ones on temperature sensitive substrates, like wood, paper and plastics, where the UV curable coatings are already well established. * Looking at UV curing as a key to scratch resistant automotive clear coats * Ecoefficiency of UV Coatings * Comprehensive overview of the technology, materials and markets

A smart coating is defined as one that changes its properties in response to an environmental stimulus. The Handbook of Smart Coatings for Materials Protection reviews the new generation of smart coatings for corrosion and other types of material protection. Part one explores the fundamentals of smart coatings for materials protection including types, materials, design, and processing. Chapters review corrosion processes and strategies for prevention; smart coatings for corrosion protection; techniques for synthesizing and applying smart coatings; multi-functional, self-healing coatings; and current and future trends of protective coatings for automotive, aerospace, and military applications. Chapters in part two focus on smart coatings with self-healing properties for corrosion protection, including self-healing anticorrosion coatings for structural and petrochemical engineering applications; smart self-healing coatings for corrosion protection of aluminum alloys, magnesium alloys and steel; smart nanocoatings for corrosion detection and control; and recent advances in polyaniline-based organic coatings for corrosion protection. Chapters in part three move on to highlight other types of smart coatings, including smart self-cleaning coatings for corrosion protection; smart polymer nanocomposite water- and oil-repellent coatings for aluminum; UV-curable organic polymer coatings for corrosion protection of steel; smart epoxy coatings for early detection of corrosion in steel and aluminum; and structural ceramics with self-healing properties. The Handbook of Smart Coatings for Materials Protection is a valuable reference for those concerned with preventing corrosion, particularly of metals, professionals working within the surface coating industries, as well as all those with an academic research interest in the field. Reviews the new generation of smart coatings for corrosion and other types of material protection Explores the fundamentals of smart coatings for materials protection including types, materials, design, and processing Includes a focus on smart coatings with self-healing properties for corrosion protection

The first edition of Radiation Technology for Polymers set the standard as a valuable, time-saving resource offering systematic fundamental information about industrial radiation technologies. Raising the bar even further, Radiation Technology for Polymers, Second Edition explores emerging applications of ultraviolet (UV) and electron beam (EB) radiation to polymer processing, detailing significant changes in the field since the first publication. Presents important new processing and engineering data from selected commercial products Since the publication of the previous edition, many technological developments have taken place, new applications and products have been developed and commercialized, and some already established ones have been discontinued. This book updates changes, trends, and general issues in radiation technology. It presents vital, cutting-edge information to aid further reduction of volatile organic compounds and toxic substances in the environment, develop alternative sources of energy, and harness energy in both medical and industrial applications. The author considers novel uses of UV/EB technology in: Equipment and instrumentation developments in automotive, electronics, and wood-processing industries Applications used in waterborne coatings and adhesives, film modifications, high-performance coatings, and inkjet technology Processing of coatings, paints, inks, and adhesives, as well as thermoplastics and elastomers in film, sheet, and other forms This reference discusses new uses for UV and EB irradiation, the response of polymers to irradiation, tests related to dosimetry and radiometry, and related safety and hygiene. It is also fortified with new problems and worked solutions, as well appendices with supplementary information on equipment manufacturers, raw materials suppliers, and principles of green chemistry and sustainability.

Schon die erste Auflage des englischen Lehrbuchs 'Fundamentals of Photonics' zeichnete sich durch seine ausgewogene Mischung von Theorie und Praxis aus, und deckte in detaillierter Darstellung die grundlegenden Theorien des Lichts ab. Es umfasste sowohl die Themen Strahlenoptik, Wellenoptik, elektromagnetische Optik, Photonenoptik, sowie die Wechselwirkung von Licht und Materie, als auch die Theorie der optischen Eigenschaften von Halbleitern. Die Photonik-Technologie hat eine rasante Entwicklung genommen seit der Publikation der ersten Ausgabe von 'Fundamentals of Photonics' vor 15 Jahren. Die nun vorliegende Zweite Auflage des Marksteins auf dem Gebiet der Photonik trägt mit zwei neuen und zusätzlichen Kapiteln den neuesten technologischen Fortschritten Rechnung: Photonische Kristalle sowie Ultrakurzpuls-Optik. Zudem wurden alle Kapitel gründlich überarbeitet und viele Abschnitte hinzugefügt, so z.B. über Laguerre-Gauss Strahlen, die Sellmeier-Gleichung, Photonenkristall-Wellenleiter, photonische Kristallfasern, Mikrosphären-Resonatoren, Optische Kohärenz Tomographie, Bahndrehimpuls des Photons, Bohrsche Theorie, Raman-Verstärker, rauscharme Avalanche-Photodioden, Abstimmkurven und Dispersions-Management.
