Abstract
Disclosed herein are electrodepositable cationic baths containing nonionic pigment dispersants. These nonionic pigment dispersants are ethoxylated styrenated phenols which allow for increased production capacity and lower VOC. The ethoxylated styrenated phenols are also used as an additive which can increase film build and improve film smoothness.
