Global market sizes for nanocoatings and coatings are expected to be $14.3 billion and $123 billion, respectively by the year 2019. Coatings can be classified according to their applications or method of preparation or type of property imparted to the product. They can be either solvent based or water based. They may comprise polymers or inorganic materials. Nanocoatings with thickness less than 100 nm can offer superior performance properties compared with conventional coatings. Nanotuff was one of the first commercial nanocoating. It contained nano-sized particles suspended in an epoxy matrix. Coatings can have specific purposes such as corrosion resistance, antiabrasive resistance, scratch resistance, chemically resistance, stain resistance to the objects they are applied on. This book contains some new theory in the areas of solubility parameter estimates using isentropic volume expansivity, compressibility, and surface tension effects during coating flows. Volume I contains separate chapters on introduction, applications, and stability. Volume II contains chapters on methods, solvents, drying and inks, and properties. Patents from leading companies such as Xerox, IBM, Intel, BASF, PPG, Boeing, Valspar, Toyota, Goodyear, Gaze Nanotech, Bell Helicopter, Procter and Gamble, and General Electric on nanocoatings are discussed in the book.
