Abstract:
The inventors of the present disclosure discovered that use of a urea-modified polyurethane coating as the topcoat in a pavement marking tape has numerous advantages. The urea-modified polyurethane topcoat is the reaction product of an aspartic ester polyamine, a polyisocynate, and a polyol. The urea-modified topcoat is adjacent to a base layer. The base layer and topcoat form a pavement marking tape.
