ABSTRACT:
A laminate which is useful as a construction material is disclosed. The laminate has a substrate layer which contains vinyl chloride polymer, a butadiene rubber graft copolymer, and has a superstrate layer which contains vinyl chloride polymer, butylacrylate rubber graft copolymer, and titanium dioxide. The superstrate layer protects the substrate layer from excessive exposure to ultraviolet light, heat and moisture, and thereby protects the substrate layer from weathering during outdoor use of the laminate as a material for siding, gutter systems, downspouts, shutters, window casings, and other exterior outdoor weather exposed building material applications.
