Abstract:
Improved aqueous electrocoating materials and methods providing improved coating deposits on metal substrates are obtained by adding an alcohol having from 1 to 8 preferably 2 to 4, carbon atoms to an organic coating resin having reactive sites at least partly but not completely neutralized, so that the alcohol is at least partly dispersed in the resin. The alcohol is preferably added before diluting the resin with water and is about 2. 0 to 20 weight percent, preferably about 10 weight percent based on the resin.
