Title: Water-based polyurethane dispersions: Chemistry, Technology and applications
Issue Date: 2013
Abstract: Over the past few decades, polyurethane-polyurea aqueous dispersions (PUDs) have developeda solid reputation for high performance applications, particularly in the field of adhesives andcoatings. PUDs are mostly environmentally compatible products; they are totally devoid orcontain only low amounts of volatile organic compounds(VOC). This is an important feature inview of the present environmental policies where governments and internal agencies are placingemphasis on developing sustainable processes, improving work conditions and reducingemissions of toxic and pollutingsubstances into the atmosphere.In the past years, our research group has beeninvolved in the development of polyurethane-polyurea aqueous dispersions for two main applications (footwear and indirect food contact).With this work we intend to review this themeand describe some of the achieved developments.Characterization of commertial dispersions will be presented and examples of synthesis will bedescribed, following a modified pre-polymer process developded in our group.
