Abstract:
A method for forming a coating on a pre-sheared, electroconductive, flat blank having two major surfaces and sheared edges, said method comprising the following steps:(1) conveying the blank to an electrodeposition bath located on a coating line; (2) applying an aqueous electrodepositable coating composition to both major surfaces and the sheared edges of the blank as the blank passes through the electrodeposition bath, the blank serving as an electrode in an electrical circuit comprising the electrode and a counter-electrode immersed in the aqueous electrodepositable coating composition, the composition being deposited onto both major surfaces and the sheared edges of the blank as a substantially continuous coating as electric current is passed between the electrodes; (3) conveying the coated blank of step (2) from the electrodeposition bath to a drying station located on the coating line; and (4) drying the electrodeposited coating as it passes through the drying station, wherein the electrodeposited coating is a post-formable coating having a T-bend rating of 0T to 6T; and (5) forming the coated blank.
