    • The present invention provides an article comprising a curable resin and a filler associated with the resin. The incorporation of fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage. The incorporation of fillers into the casting materials of the present invention also imparts air and vapor porosity to the cured casting materials. If desired articles of the present invention may also incorporate fibers (either individually, bundled, or in the form of a light-weight scrim) to provide increased cohesiveness to the uncured article. Extremely moldable casting tapes are also provided which comprise a highly-filled composite material coated on a light-weight scrim. The casting tapes of this embodiment handle like traditional plaster of Paris casts yet cure to a weight-bearing cast in less than one hour. The ratio of the volume of filler to volume of prepolymer or resin is >0.40.
    • 本发明提供一种包含可固化树脂和与树脂相关的填料的制品。 本发明的浇铸材料中填充剂的添加基本上增加了固化的浇铸材料的强度以及未固化的浇铸胶带或绷带的操作性能。 将填料掺入本发明的铸造材料中也赋予固化的浇铸材料空气和蒸汽孔隙率。 如果需要,本发明的制品还可以加入纤维(单独地,捆扎的或以轻质稀松布的形式),以提供对未固化制品的增加的粘合性。 还提供了非常可成型的铸造带,其包括涂覆在轻质稀松布上的高填充复合材料。 本实施例的铸造胶带处理像传统的巴黎铸造石膏,但在不到一小时的时间内固化成承重铸件。 预聚物或树脂的填料体积与体积的比值> 0.40。
