Autodeposition coatings are thin, highly corrosion resistant organic coatings that deposit paint by reaction with the metal surface. The coating deposits only on metallic surfaces, thus allowing coating of just the metal portion of metal-plastic or metal-rubber assemblies. Because it is a chemical reaction with the metal surface, it is possible to evenly paint the inside of tubular and boxed sections, which is where corrosion typically starts. The overall autodeposition process includes cleaning, water rinse, coat, reaction rinse, and cure. The use of a reaction rinse after the autodeposition coating application allows unique properties to be introduced to the coating before curing.This presentation will briefly review the general chemistry of autodeposition. Next it will focus on commercial automotive applications of several newly developed autodeposition coatings. The corrosion performance and physical characteristics of both black and gray epoxy-acrylic coatings will be presented. The coatings are being used as stand-alone coatings and as primers for topcoated applications. Data from several commercial vehicle and automotive parts lines will be presented. These data will demonstrate the unique properties and advantages of autodeposition coatings in meeting stringent automotive corrosion and appearance requirements.
