Protective coating system for imparting resistance to abrasion, impact and solvents |
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 is a highly crosslinked hard polymer, which is adhered to an underlying base coating layer of a compatible softer polymer. The outer hard polymer preferably comprises a highly crosslinked acrylic copolymer derived from at least 40 percent by weight of a multifunctional aliphatic acrylate monomer of three or more functional groups, while the underlying softer polymer preferably comprises a crosslinked aliphatic urethane acrylate copolymer and the multifunctional aliphatic acrylate monomer of three or more functional groups.
