Abstract
Waterborne polyurethane coating compositions comprising a polyol, an isocyanate crosslinker, and a small amount of thermoplastic microfibers, e.g., polyolefin microfibers, having a length of less than 1 mm, exhibit a much less sag, roller lines and other surface imperfections upon application to a substrate, in particular a vertical substrate such as a wall, than analogous water borne polyurethane compositions that lack the microfibers.
