Development of environmentally friendly recipes water dispersion polyurethane compositions
Scientific and practical interest in water-dispersion polyurethane compositions due to their exceptionally high quality and such properties as a good drying rate, atmospheric, water, chemical, abrasive, frost and heat resistance, excellent adhesion to various substrates. This article provides information about the prospects and areas of use of water-dispersive polyurethane compositions. The method of obtaining dispersions in an energy-saving way that meets global environmental requirements is considered. For coatings and adhesives with high consumer properties, water-dispersed polyurethane dispersions based on domestically produced polyesters were synthesized and their colloidal chemical properties were studied. The results of the experiments showed that the compositions developed have characteristics that are not inferior to industrial analogues. The resulting polyurethane compositions can be used as adhesives for 3D bonding, as well as coatings for wood and plastic.
