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

Photoinitiating systems for polymerization reactions are largely encountered in a variety of traditional and high-tech sectors, such as radiation curing, (laser) imaging, (micro)electronics, optics, and medicine. This book extensively covers radical and nonradical photoinitiating systems and is divided into four parts: * Basic principles in photopolymerization reactions * Radical photoinitiating systems * Nonradical photoinitiating systems * Reactivity of the photoinitiating system The four parts present the basic concepts of photopolymerization reactions, review all of the available photoinitiating systems and deliver a thorough description of the encountered mechanisms. A large amount of experimental and theoretical data has been collected herein. This book allows the reader to gain a clear understanding by providing a general discussion of the photochemistry and chemistry involved. The most recent and exciting developments, as well as the promising prospects for new applications, are outlined.
Growing interest in the formulation of pressure-sensitive adhesives as described in the first edition of this book ( Pressure-Sensitive Formulation, VSP, 2000) required a new, enlarged edition including the design of pressure-sensitive adhesives as a separate volume. Developments in the understanding of pressure sensitivity were necessary to use ma
This volume compiles a wealth of information on the composition, properties, utilization, and performance of major classes of additives while alerting formulators to potentially damaging interactions and challenges in the selection and testing of these materials.

APPLIED COATINGS An integrated collection of case studies providing a concise guide for professionals working with coatings materials in academia and industry In Applied Coatings: Chemistry, Formulation, and Performance, distinguished scientist Dr. Weih Q. Lee delivers an illuminating collection of case studies designed to connect various elements of applied coatings technology. Going beyond generic discussions, the author describes the fundamental chemistry, formulations, and properties of applied coating materials – including the structural and functional components of structure-property relationships – as well as the foundations of applied cure kinetics and the rheology of epoxy coatings. Each chapter is self-contained, comprehensive, and can be read individually, while the book remains technically and editorially integrated. Core themes include structure-performance relationships, formulation index driven experiment design, and consolidated thermal analysis. Readers will also find: A thorough introduction to epoxies and epoxy curing agents, including oxetanes, vinyl esters, glycidyl methacrylate (GMA), isocyanate and silicone crosslinkers, cationic catalysts, acrylate and phenol accelerators, and specialty derivatives Attentive descriptions of epoxy curing chemistry, including epoxy-phenolic, -polyamide, -active ester, and acid- or base-catalyzed systems in a broader scope Comprehensive explorations of cure kinetics and rheology, including model-free kinetics (MFK), the nth-order model covering Kissinger plots and the Borchardt—Daniels (BD) approach, the autocatalytic model, executive quantification via curve fitting of DSC (differential scanning calorimetry) exotherms, the rheology of non-reactive fluids, and the viscoelasticity of reactive coatings Practical discussions of C1S thick-film surface coatings, C2S structural lamination, liquid and powder epoxies, and phenolic coatings, including fluorene monomers, heterocyclic resins, and polymerizable derivatives Complete treatments of coating characterization, microencapsulation, epoxy hybrids and non-epoxy platforms, adhesion of applied coatings, and adhesion promotion, including reactive and functional silicones Perfect for formulation and research and development scientists and engineers at any technical level, Applied Coatings will also benefit research professors and students studying coatings, adhesives, composites, electronic materials, and more.
