Abstract
Electrodeposition of resin by rectangular pulse current was studied in acrylic paint solutions. Analyses of responsed potential-time curves to the applied current revealed an inductance term as a nonfaradaic portion. The inductance calculated from the potential-time curve varied from 0 to 300 (mH-dm2) with resin concentration from 0.01 to 32%. In order to interprete the inductance observed at paint deposition stage, the coulombic yields, required bath voltage, and the properties of deposited paint film, such as tackiness and corrosion resistance, were measured at various resin concentrations and the observed inductance is tentatively interpreted in terms of the morphology of the resin particles.
