ELECTROCOATING COMPOSITIONS CONTAINING HIGH ASPECT RATIO CLAYS AS CRATER CONTROL AGENTS

摘要

Provided are cationic electrodepositable compositions comprised of an acidified aqueous dispersion of (a) an ungelled cationic resin, (b) a curing agent having at least two functional groups which are reactive with (a), and (c) an exfoliated silicate derived from a layered silicate. These compositio ns exhibit improved crater control. Also provided is a method of electrocoating conductive substrates using such compositions.
