Abstract
A substrate may be coated with a various combinations of a water-dispersible polyisocyanate, a water-soluble acid or salt thereof, and/or an isocyanate-reactive compound. The resulting coated article has improved coating adhesion, especially near coated burnished surfaces such as sawn edges or grooves.
