Beschreibung
Zusammenfassung:	本发明在第一个实施方式中提供一种封闭蜡组合物，所述封闭蜡含有约50-约90重量％的水溶性连续相和约10-约50重量％的不连续固体相填料，所述不连续相填料与所述连续相基本上不反应。本发明还提供了一种用于加工的接触透镜坯料的安装方法。 The invention provides, in a first embodiment, a blocking wax composition. The blocking wax comprises from about 50 to about 90 weight percent of a water-soluble continuous phase and from about 10 to about 50 weight percent of a discontinuous solid phase filler that is substantially inert to the continuous phase. The invention further provides a method for mounting a contact lens blank for machining.
