Abstract
An improved aqueous electrocoating composition having a binder of an epoxy-amine adduct and a blocked polyisocyanate crosslinking agent; wherein the improvement is the use of an antioxidant additive which is a combination of a phenolic antioxidant and a sulfur-containing antioxidant. The additive reduces overbake yellowing of the composition and the intercoat delamination of the composition and the topcoat upon exterior exposure.
