用于水性电泳涂装的不含有机溶剂的颜料分散剂
摘要：
本发明公开了颜料分散树脂和颜料分散体、使用所述颜料分散树脂的可电沉积涂料组合物、以及施用所述可电沉积涂料组合物的方法。所述颜料分散树脂基本上由胺化的双酚环氧树脂的羧酸盐和烷氧基化的苯乙烯酚组成。由分散树脂制成的颜料分散体尤其可用于形成低挥发性或无挥发性有机成分的电泳涂装浴。
摘要（英）：

A pigment dispersing resin is disclosed along with pigment dispersion, electrodepositable coating compositions using the pigment dispersing resin, and methods for applying the electrodepositable coating composition. The pigment dispersing resin consists essentially of the carboxylic acid salt of an aminated bisphenol epoxy resin and an alkoxylated styrenated phenol. Pigment dispersions made from the dispersing resin are especially useful for forming low or no volatile organic content electrocoating baths.
