    Abstract: The invention relates to multilayer composites having improved weathering properties without reducing flame retardation properties. The composites have a fluoropolymer layer over a thermoplastic layer. The multilayer composite may be a fluoropolymer layer directly over a relatively flammable substrate or non-flammable substrate (like PVC), or it may be a fluoropolymer layer over a relatively flammable cap layer, over a substrate (that is flammable or non-flammable). The composite is formed using coating, coextrusion and/or lamination techniques. The multilayer composite is especially useful in articles having surfaces that are used in a relatively horizontal position, including decking, railings, roofing and window profiles. The composites provide improved weathering for the substrate without a reduction in flame-resistance, when compared to the substrate without the outer fluoropolymer layer. The multi-layer composite also provides enhanced chemical resistance, hardness, scratch and mar, and water resistance.

    Abstract translation: 本发明涉及具有改善的耐候性而不减少阻燃性能的多层复合材料。 复合材料在热塑性层上具有含氟聚合物层。 多层复合材料可以是直接在相对易燃的基材或不可燃的基材（例如PVC）上的含氟聚合物层，或者它可以是在相对可燃的盖层上方的氟聚合物层，在基材上（即可燃或不可燃的） 。 复合材料使用涂层，共挤出和/或层压技术形成。 多层复合材料在具有在相对水平位置使用的表面的制品中特别有用，包​​括甲板，栏杆，屋顶和窗户型材。 当与没有外部含氟聚合物层的基材相比时，复合材料在不降低阻燃性的情况下为基材提供改进的耐候性。 多层复合材料还提供增强的耐化学性，硬度，划痕和耐水性。
