The pressing need to use environmentally friendly materials has push the research and development of waterborne polyurethanes (WBPUs). These polymer dispersions, release benign water vapor to the atmosphere during the preparation of supported or self-standing films instead of huge amounts of volatile organic compounds (VOCs), as is the case with most traditional solvent-based polymers. One of the most studied applications for this type of material is water-based paints for coatings applications. This chapter is devoted to analyze the latest advances regarding the development of WBPU as neat and composite formulations developed as specific coatings for different types of substrates.
