    Abstract: A coating system comprises a basecoat of an thermosetting asphalt extended, chemically cross linkednullurethane/epoxy hybrid basecoat resting on a substrate, preferably a porous substrate such as concrete or wood that off-gas when coated with a thermoplastic material; and a thermoplastic powder coating topcoat overlying at least the base coat. The thermosetting basecoat composition consisting essentially of, in weight percent based on final formulation, and between 10 and 90% of a petroleum asphalt; between 10 and 90%, of a hydroxy-terminated homopolymer; and between 0.1 and 30% of a functional epoxy reactive diluent for reducing the viscosity of the composition; and further up to 5% of a surfactant for improving surface imperfections, up to 5% of an anti-oxidant; and up to 25% of a thickening agent.

    Abstract: Method for preventing the formation of coating defects in polymeric coated surfaces in a coating process comprising a plurality of steps that occur prior to the polymeric coating of said surfaces and that contact organic and metal surfaces with a plurality of aqueous compositions in which accumulate in suspension resin particles released from said metal surfaces. Suspended resin particles are prevented from re-depositing on the organic surfaces by converting said surfaces to hydrophilic character by means of oxidizing said surfaces prior to contacting the oxidized surfaces with said suspensions.
