Abstract
Cationic electrocoat latices, containing blocked isocyanate crosslinker and which are usually unstable toward pumping and shear forces, can be stabilized by conducting the emulsion polymerization in a solvent-water mixture containing from about 20 to 30 percent solvent. Ethanol is a preferred solvent. Preferably the crosslinker is first emulsified and then added to the emulsion polymerization system prior to or during polymerization to produce mechanically stable latex that is virtually free of grit.
