Abstract
Waterborne polyurethane dispersions used in surface coatings have recently gained a lot of interest as the need for more and more alternatives in the case of chemical components has arisen. Nevertheless, WPUDs can be used to obtain coatings with superior qualities. Hence, a study of various research papers, articles, and other literature is being presented in the following review article. We have studied various aspects of improvement and advancement in the field of WPUDs. We have focused mainly on thermal and mechanical property elevation brought about by physical and chemical modifications. We have also described raw materials and the basic chemistry of WPUDs taking into consideration how properties can be achieved by alterations in these two aspects as well.
