This edited book compiles all category viewpoints in waterborne polyurethanes (WPUs) dispersions, composites, characterizing techniques, and allied applications such as coatings, adhesives, sealants, anticorrosive, flame-retardant, and biomedical applications. The book brings together panels of highly accomplished experts in the field of advanced polymers for versatile applications. It encompasses basic studies and addresses topics of novel issues which cover all the aspects in one place. The book is an invaluable guide to newcomers, research scholars, professors, and R&D industrial experts working in the field of polyurethane chemistry. Polyurethanes are excellent materials in coating technology owing to their chemical resistance, toughness, abrasion resistance, and mechanical stability. However, polyurethane dispersion contains volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) which are harmful to the environment. Hence, green chemistry research focuses on discovery of waterborne polyurethanes (WPUs) and pay attention. WPUs have fascinated growing interest in wide range of industrial and commercial applications.
