Autodeposition Of Organic Coatings

摘要

Auto deposition of organic coatings refers to a chemical process for depositing paint coatings onto metal surfaces. This process resembles electrodeposition in that the objects to be coated are submerged in an aqueous bath containing ionized organic materials; however, in autodeposition, the coating is produced by a chemical reaction between the metal surface and the bath constituents as opposed to electrodeposition where the coating is produced by the electrolysis of water due to an imposed electric current. After autodeposition, the wet film is water rinsed and cured by application of heat to produce an inert, corrosion-resistant coating.
