Zusammenfassung: | The present disclosure relates to an electrodepositable coating composition comprising: an electrodepositable binder comprising a film-forming polymer comprising ionic salt groups and a curing agent; and at least one pigment; wherein the electrodepositable coating composition has a resin solids content of less than 30% by weight, based on the total weight of the electrodepositable coating composition, and a viscosity of at least 15 cP at a shear rate of 0.1/sec, as measured by the bath viscosity test method; and wherein the pigment optionally comprises a phyllosilicate pigment, and if the electrodepositable coating composition is a cationically electrodepositable coating composition and a pigment dispersing acid is present in the cationically electrodepositable coating composition, the pigment optionally comprises a phyllosilicate pigment. The ratio of pigment to binder of the phyllosilicate pigment to the electrodepositable binder is less than 0.2: 1. A coating, a coated substrate, and a method of coating a |
