Polyols can be divided into latex polyol and dispersion polyolaccording to the way of preparation. In this paper, acrylic latex polyol and acrylic dispersionpolyol were synthesized respectively. One kind waterborne polyisocyanate, which was waterbornehexamethylenediisocyanate trimer, was obtained by hydrophilic modification. Andisophorone diisocyanate trimer (T1890E), which can formulate into 2K-WPU coatings withpolyols, was selected from the unmodified polyisocyanates.
