The title of this book has been chosen to reflect the combination of basic knowledge and applied science on paints and coatings. The dizzying advance of the science of materials prompted editors to try to produce a book that occupies that space with a scientific-technological approach. The book is also intended to raise awareness of the many underlying knowledge aspects for the successful use of new materials for the formulation and manufacture of paints and coatings that simultaneously exhibit efficiency, are economical, and meet requirements that seek to reduce pollution.Researchers specializing in painting technology and materials science in general, the academic community that participates in postgraduate teaching tasks and particularly the professionals who make up the productive sector, surely have different expectations in reading this book. Editors want at least some of the above objectives to be achieved; thus, this book will have reached its purpose.The first chapter reports on the novel results obtained for high performance silica-polymethyl methacrylate (PMMA) and silica-epoxy coatings, containing active corrosion inhibitors, such as cerium salts; also, it compares their properties with results reported for a variety of hybrid coatings prepared by different approaches and formulations.The next chapter refers about the production of thin films (nano coatings); it is a technological field with many applications to elaborate materials with new properties to be used as corrosion protection of traditional metals. Two hydrophobic corrosion coatings for possible use over aluminum heat exchanger geothermal power plants are described.In other chapter, since the electrodeposition is a low-cost and low-temperature method for producing metal matrix composite coatings and for attending the combined mechanisms of corrosion and erosion, it has been studied monolayers and multilayers alloy systems deposited applying this process (composites coatings trough the co-deposition of nanoparticles).The following chapter reports a proposal for reducing the predominant asset of the investment cost for proton exchange membrane (PEM) electrolyzer by using protective and easily up-scalable coating technologies. Vacuum plasma spraying, a versatile technology for applaying various types of coatings to a wide range of surfaces, is described to produce highly stable and multifunctional coatings for cost effective interconnectors of PEM electrolyzers.
