Abstract: A water-based cutting fluid that comprises water and a water-soluble polyalkylene glycol (PAG) having cloud point from 30° C. to 80° C. The cutting fluid is water-based, i.e., it comprises at least 50 percent by weight (wt %) water. The cutting fluids are well suited for use with diamond wiresaws for the cutting of silicon ingots. The fluids exhibit one or more of low hydrogen generation, no wafer cleaning issues, good lubricity, good cooling efficiency, good swarf suspension and dispersion, low foaming, are generally non-sensitive to metal ions, and are nonflammable.
Abstract translation: 一种水性切削液，其包含水和水溶性聚亚烷基二醇（PAG），其浊点为30℃至80℃。切削液为水基，即其包含至少50重量％ （重量％）水。 切削液非常适合用于切割硅锭的金刚石线锯。 流体表现出一个或多个低氢产生，没有晶片清洗问题，良好的润滑性，良好的冷却效率，良好的切屑悬浮和分散性，低起泡性，通常对金属离子不敏感，并且是不可燃的。
