This is due to the unique solubility and evaporation rates provided by “urethane grade” solvents. It is commonly used for treating and protecting parquet floors and wooden stairs. Sorry I'm not really a polymer chemist. They are typically rendered thinner and liquid using either water or a commercial retardant that may contain ingredients such as propylene glycol. Automotive refinish primers, basecoats, and clearcoats require “urethane grade” solvents to be used in their reducers. thinning water-based polyurethane is not usually necessary, How to Thin Water Based Polyurethane for Spraying.
