摘要：This invention relates to a coating system which forms a highly abrasion
resistant, chemical resistant, impact resistant protective finish for a substrate. The coatingsystem is based upon using two coatings of different characteristics but having excellentadhesion to one another. The outermost or surface coating layer is a highly crosslinkedhard polymer, which is adhered to an underlying base coating layer of a campatiblesofter polymer. The outer hard polymer preferably comprises a highly crosslinked acrylicpolymer, while the underlying softer polymer preferably comprises a crosslinkedurethane polymer.
