Abstract:
Disclosed herein are electrodepositable coating compositions comprising a film forming resin and a textured additive, wherein the textured additive has a density (specific gravity) of no more than 4.5 g/cc and a melting point greater than the curing temperature of the electrodepositable coating composition. Also described are coated substrates having a cured coating layer comprising the electrodepositable coating composition, wherein the cured film layer has a texture of at least 250μ-in as measured by a profilometer at conventional cured film thicknesses.
