    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 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.

    摘要: A system and method for treating a surface to both cover existing graffiti thereon and to facilitate removal of subsequently applied graffiti. A two part, water-based epoxy is initially applied to the surface. After drying thereof, a top coat system including an aliphatic urethane color component, a catalyst and a hardener is applied directly over the epoxy and permitted to dry. Upon drying, subsequently applied graffiti may be easily removed by the use of a solvenated cleaner.
