| 摘要 |
<p>This invention relates to a coating system which forms a highly abrasion resistant, chemical resistant, impact resistant protective finish for a substrate. The coating system is based upon using two coatings of different characteristics but having excellent adhesion to one another. The outermost or surface coating layer (15) is a highly crosslinked hard polymer, which is adhered to an underlying base coating layer (16) of a compatible softer polymer. The outer hard polymer (15) preferably comprises a highly crosslinked acrylic polymer, while the underlying softer polymer (16) preferably comprises a crosslinked urethane polymer. <IMAGE></p> |
