摘要: Polyurethane coating compositions that provide transparent, abrasion-resistant, and water-washable anti-fog coatings when applied to a substrate and cured are described herein. These polyurethane coating compositions have surfactants that are chemically associated with the polyurethane so as to not leach out or wash away when the coating surface is soaked or washed with water. The polyurethane coating compositions comprise isocyanate-reactive surfactants, isocyanate-reactive salts of surfactants, carboxylic-reactive surfactants, or combinations thereof that are chemically bonded to the polyurethane. Articles coated with such polyurethane coating compositions, and processes for applying the coating compositions to a substrate, are also provided herein.
摘要翻译: 本文描述了当应用于基材和固化时提供透明,耐磨和防水的防雾涂料的聚氨酯涂料组合物。 这些聚氨酯涂料组合物具有与聚氨酯化学结合的表面活性剂,以便当涂层表面被浸泡或用水洗涤时不会渗出或洗掉。 聚氨酯涂料组合物包含与聚氨酯化学键合的异氰酸酯反应性表面活性剂,表面活性剂的异氰酸酯反应性盐,羧基反应性表面活性剂或其组合。 本文还提供了涂覆有这种聚氨酯涂料组合物的物品,以及将涂料组合物施用于基材的方法。

摘要: A hydrophilic polymer blend is disclosed which comprises a first polymer component which is an organic solvent-soluble, thermoplastic polyurethane and a second polymer component which is a hydrophilic poly(N-vinyl lactam), e.g., a water soluble polyvinylpyrrolidone. The blend demonstrates slipperiness is aqueous environments and, among other applications, is useful in low-friction coatings for a wide variety of substrates.
