Abstract
The present invention relates to polyurethane coatings and to processes for preparing and applying said coatings whereby a prepolymer composition comprising a moisture-curable prepolymer and a plasticizer is prepared and applied to a substrate. When cured, the coated substrate demonstrates good wearability, stain resistance, and appearance, yet the use of volatile solvents may be avoided.
