Over the past three years, the number of commercial installations in North America employing autodeposition processes to apply organic coatings to metal surfaces has increased from six to twenty, while the annual square footage has increased three-fold - a rate which will continue to grow in the near future. The advantages of autodeposition in coating severely recessed areas and complex composite assemblies are well known. This paper highlights recent developments in autodeposition coatings for zinc and cast iron surfaces plus the commercialization of novel curing techniques. Equipment considerations for the process are also discussed.
