Abstract: Two-layer protective coating system for glass surfaces is disclosed. The base coating comprises at least one polysaccharide, and the top coating has a lower solubility in water than the base coating. The coating system provides good protection against contaminants and glass chips, good removability in mild cleaning condition, and extra water resistance during process steps where water is used as a cooling agent.

Abstract: Removable coatings for protecting glass sheets and, in particular, for protecting LCD glass sheets during cutting, grinding, shipping, and/or storage are provided. The coatings comprise one or more polysaccharides, with the preferred polysaccharides being starches composed of a mixture of amylose and amylopectin molecules. The coatings can be removed from the glass sheets using water solutions, e.g., a mild detergent solution, in combination with, for example, ultrasonic cleaning and/or brush cleaning. After removal, the glass sheets have substantially the same surface characteristics and chemistry as untreated sheets and also have particle/contamination levels equivalent to those of control sheets held in a clean environment.

Abstract translation: 提供了用于保护玻璃板的可移除涂层，特别是用于在切割，研磨，运输和/或存储期间保护LCD玻璃板。 涂层包含一种或多种多糖，优选的多糖是由直链淀粉和支链淀粉分子的混合物组成的淀粉。 可以使用水溶液（例如温和的洗涤剂溶液）结合例如超声波清洗和/或刷洗从玻璃板中除去涂层。 去除后，玻璃板具有与未处理片材基本上相同的表面特性和化学性质，并且还具有与在清洁环境中保持的对照片材相当的颗粒/污染水平。
