ABSTRACT:
The present invention provides a method of delustering an electrocoated article which comprises dipping an uncured electrocoated article into an aqueous solution of an organic sulfonic acid, and applying electric voltage to the article. Further, the present invention provides a method of controlling the gloss of an electrocoated article which comprises electrocoating an article while applying pulsating electric current voltage, dipping the obtained electrocoated article in an aqueous solution of an organic sulfonic acid in an uncured state, and applying electric voltage to the electrocoated article as anode, wherein certain pulsating ratio at electrocoating is selected. According to the present invention, an even delustered coat having excellent physical properties is obtained. Further, it is possible to deluster the electrocoat to a desirable gloss with eveness.
