Patent ID: 8034455

Claim:
A coating system, comprising: a liquid primer coat composition comprising a silane adhesion promoter; a liquid base coat ultraviolet (UV) curable composition comprising one or more UV oligomers comprising at least one aliphatic urethane acrylic oligomer; at least one acrylate diluent monomer selected from a mono-, bi-, or tri-functional reactive acrylate diluent monomers; a leveling agent; and at least one photo-initiator, that does not comprise a surface cure agent; and a liquid top coat UV curable composition comprising one or more UV oligomers comprising at least one aliphatic urethane acrylic oligomer; at least one acrylate diluent monomer selected from a mono- or a bi-, functional reactive acrylate diluent monomers; at least one photo-initiator; or a non-conductive pigment, wherein each of the base coat composition and the top coat composition do not comprise a solvent and do not comprise an adhesion promoter.
