ELECTRODEPOSITABLE COATING COMPOSITIONS HAVING IMPROVED CURE RESPONSE |
摘要 |
An improved electrodepositable composition is provided comprising: (a) an active hydrogen-containing cationic resin electrodepositable on a cathode; (b) a capped polyisocyanate curing agent; and (c) an organotin-containing catalyst. The improvement comprises the addition to the electrodepositable composition of a water immiscible acid functional compound having a hydrocarbon chain of at least 5 carbon atoms. The composition provides improved cure response and appearance properties when electrodeposited over conductive substrates.
