CATHODIC ELECTROCOATING PROCESS AND COMPOSITION

摘要

- This invention relates to novel compositions and to a process for preparing an electrocoated article which comprises maintaining a liquid bath composition having dispersed therein: (a) particles of an amine-containing organic coating material having a positive charge in combination with (b) a blocked multifunctional isocyanate; maintaining a first electrode in intimate electrical contact with said bath as anode; immersing in said bath as a second electrode a conductive article at least a portion of which bears a negative charge as cathode; passing an electric current through said electrodes and said bath thereby electrocoating said conductive article; and heating said electrocoated article after removal from said bath to form a water-resistant crosslinked polymerized electrocoated surface on said electrocoated article.
