Electrodepositable coating composition containing bismuth diorganodithiocarbamates and method of electrodeposition

摘要

An electrodepositable composition is provided comprising (a) an active hydrogen-containing, cationic salt group-containing resin electrodepositable on a cathode; (b) a capped polyisocyanate curing agent; and (c) bismuth diorganodithiocarbamate. Such compositions may be prepared without the use of conventional lead or tin catalysts and exhibit excellent properties as cured coatings. Also provided is a method of electrocoating an electroconductive substrate using the composition of the present invention.
