Abstract
Embodiments of the present disclosure include processes for autodepositing a coating on a metal surface, a method of producing a coating on a non-stainless steel metal substrate surface, and an alkaline coating composition, where the process for autodepositing a coating on a metal substrate surface includes immersing at least a portion of the metal substrate surface in a coating composition that includes a latex and an amount of base sufficient to raise the pH of the composition to an alkaline pH, where the coating autodeposits on the metal substrate surface, as metal ions from the metal substrate surface interact with the alkaline coating composition.
