Coating System for a Porous Substrate Using an Asphalt-Containing Thermosetting Basecoat Composition and a Thermoplastic Top Coat Composition |
摘要 |
A coating system comprises a basecoat of an thermosetting asphalt extended, chemically cross linked-urethane/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.
