摘要： The present disclosure is directed to an electrodepositable coating composition comprising (a) an active hydrogen-containing, ionic salt group-containing film-forming polymer: (b) an at least partially blocked polyisocyanate curing agent: (c) a curing catalyst; and (d) an edge control additive: wherein the electrodepositable coating composition has a gel point of less than 150° C. as measured by the GEL POINT TEST METHOD, an edge coverage of greater than 20%, as measured by the EDGE COVERAGE TEST METHOD, and an Ra of no more than 0.45, as measured by the SURFACE ROUGHNESS TEST METHOD. Also disclosed are methods of coating substrates, coatings, and coated substrates.
