Abstract: Coatings for a surface, coating compositions, articles coated with a coating, and methods of coating are disclosed in which the coating comprises a polymer blend of polyurethane as a major component and at least one other polymer P2 having in comparison to polyurethane a higher peel strength to the surface to be coated, a higher percent elongation at break when cured, and a lower glass transition temperature, the polymer blend having been cured to form a peelable and flexible layer having a textured surface.
