    • The invention relates to novel aqueous coating compositions containing epoxy urethane (glycidyl carbamate) functional resin. An aqueous coating composition comprises a polyfunctional oligomer having at least two epoxy urethane functional groups and a polyalkylene oxide chain, a surfactant and water. The aqueous coating compositions of the invention can be dispersed in water with added surfactants to form a dispersion containing no volatile organic solvent. The invention provides a method for making aqueous coating compositions containing epoxy urethane functional resin as well. Water-dispersible epoxy urethane compounds of the aqueous coating compositions are also provided.
    • 本发明涉及含有环氧氨基甲酸酯(缩水甘油氨基甲酸酯)官能树脂的新型含水涂料组合物。 水性涂​​料组合物包含具有至少两个环氧氨基甲酸酯官能团和聚环氧烷链,表面活性剂和水的多官能低聚物。 本发明的水性涂料组合物可以用添加的表面活性剂分散在水中以形成不含挥发性有机溶剂的分散体。 本发明提供一种制备含有环氧氨基甲酸酯官能树脂的水性涂料组合物的方法。 还提供了水性涂料组合物的水分散性环氧聚氨酯化合物。
