BOOKSHELF Applied Surface Thermodynamics – Second Edition In reviewing this comprehensive reference book I soon discovered how much the physical chemistry of surface thermodynamics had evolved since my own academic studies some sixty years ago. I was not overawed by the mathematical treatment of interfacial surface tensions, but I found that the overall layout of this thirteen chapter book presented the reader with an understandable introduction to the macroscopic thermodynamics of interfaces. This is fundamental knowledge for coatings formulators who are called upon to resolve the problems of coating difficult surfaces and the effect that interface surface tension can have upon film flow, uniformity and subsequent interfacial adhesion. While much of the book pays attention to liquid interfacial forces the basic theories are also applicable to the response of molten solids where molecular mobility is much lower. The first eight chapters are mainly devoted to the theories of surface dynamics and applications of these principles, while the five remaining chapters are devoted to the surface tension of particles and their behaviour. The text is well supported by diagrams, drawings and photographs. The sheer amount of information contained in this book and the excellent references at the end of each chapter, make this book a valuable addition to any technical library.

POWDER
MARKETS Powder coatings: growth driven by shift to solvent-free formulations The powder coatings industry continues to grow, aided by tougher environmental rules for paints and coating that have prompted producers to turn to solvent-free formulations. Powder coatings offer a number of benefits, but the main one is that they do not need solvents, and only minimal quantities of volatile organic compounds are emitted during the curing phase. The global powder coatings market is forecast to continue to grow in the coming years, with the Asia Pacific region posting the highest growth rate. The biggest application market is the industrial segment, with the automotive sector appearing to have the most potential for growth.

Pimp my ride: powder coatings in the car industry The biggest challenge facing the car industry is how to continue to advance while keeping in touch with customer demand. Consumers are looking for environmentally friendly cars that are cheap. The changes that are taking place also extend to paint. Traditionally, the car industry, from OEM to consumers, use liquid paints for vehicle topcoats. Alternatives are starting to become more viable, including powder coatings. AkzoNobel recently launched a new powder coating to specifically address this shift in the market. Part of the Interpon A5000 range, it became the first ever full body monocoat powder coating to be used on a passenger vehicle in Europe when it was showcased by PSA Peugeot Citroen on a DS4 at the SURCAR 2011 Congress.
C O AT I N G S Many of the challenges faced by the average 21st century car maker can be addressed with powder coatings, from lowering costs and increasing energy efficiency to reducing greenhouse gas emissions. While traditional liquid paints require four coats, powder coatings only need two layers. This results in reduced complexity, reduced processes and ultimately reduced energy consumption in the paint shop. Another advantage of using a powder coating is that it is solid. No solvents are used during manufacture, so powder paint contains no VOCs. This means a 50% reduction for the OEM. Powder coating can be repaired with standard liquid paints using a standard AkzoNobel care refinishing system to it shouldn’t cost the consumer any extra to repair than a car coated with a normal liquid clearcoat. Today, AkzoNobel has a global lead supply position in the wheel component market segment. By the end of the 1980s, the performance features led to the use of powder coatings as a clearcoat for aluminium wheels. With the growth in the number of vehicles manufactured globally on the increase, powder coatings are well poised to pounce. The market for powder topcoats is wide open, as less than 10% of the bodycoat market is currently powder. Demographically, this growth will primarily be driven by the BRIC nations, particularly in the Asia Pacific region and India. The traditional western OEMs will also benefit as companies such as General Motors spread their wings into their markets. AkzoNobel’s Power Coatings business is innovating and leading the way for its customers. Its automotive powder business focuses on coatings for new cars, while the liquid paint car refinishes business deals with repair work. Its speciality paints business also provides coatings for plastic components. The next step in powder’s evolution is to create base colour coats for 7
