    • A polymeric wall covering material that is used to cover surface imperfections consists of a thermoplastic polymer coated to the surface of a nonwoven fiber tissue or mat. The polymeric coating on the fiber tissue or mat reduces paint consumption as compared with traditional glass fiber wall coating materials. In another preferred embodiment, the polymeric material contains a mineral filler to improve adhesion of a paint to the polymeric surface. In addition, an opacifying agent may be added to the polymeric material to improve hiding and improve paint adhesion. Further, a surface structure may be embossed to the applied polymeric coating during extrusion to facilitate painting with a roller-type applicator. Finally, the polymeric surface formed on the fiber tissue or mat may be subsequently treated with a corona discharge treatment to increase surface energy and adhesion.
    • 用于覆盖表面缺陷的聚合物覆盖材料由涂覆在非织造纤维织物或垫子表面上的热塑性聚合物组成。 与传统的玻璃纤维壁涂层材料相比,纤维组织或垫子上的聚合物涂层减少了涂料消耗。 在另一优选实施方案中,聚合物材料含有矿物填料以改善涂料与聚合物表面的粘合性。 此外,可以向聚合物材料中加入遮光剂以改善遮盖性并改善涂料的附着力。 此外,在挤出期间,表面结构可以压印到施加的聚合物涂层上,以便于用辊式涂布器进行涂漆。 最后,可以用电晕放电处理来在纤维组织或垫上形成的聚合物表面进行处理,以增加表面能和粘合力。
