Abstract

Un método para separar revestimientos múltiples que comprenden al menos un revestimiento químico orgánico exterior y un revestimiento metálico interior a partir de objetos metálicos revestidos, caracterizado por las etapas de tratar los objetos en una primera solución en la que los objetos se someten a un campo ultrasónico a fin de separar sustancialmente el revestimiento químico orgánico exterior de los objetos, y subsiguientemente hacer pasar los objetos limpiados a una segunda solución que es efectiva para separar el revestimiento metálico interior.
