自动沉积利用化学反应在金属工件上沉积耐腐蚀的有机涂层。离子交换技术的创新已被开发和商业化，它选择性地从涂层槽中去除化学涂层反应的副产物。这项新技术显著提高了涂层转移效率，减少了自动沉积过程中的废水。

AUTODEPOSITION UTILIZES CHEMICAL REACTIONS TO DEPOSIT A CORROSION-RESISTANT ORGANIC COATING ON METAL WORKPIECES. INNOVATIONS IN ION EXCHANGE TECHNOLOGY HAVE BEEN DEVELOPED AND COMMERCIALIZED WHICH SELECTIVELY REMOVE BY-PRODUCTS OF THE CHEMICAL COATING REACTIONS FROM THE COATING BATH. THIS NEW TECHNOLOGY SIGNIFICANTLY INCREASES COATING TRANSFER EFFICIENCY AND DECREASES WASTE EFFLUENT FOR THE AUTODEPOSITION PROCESS.
