Abstract

Un método de tratamiento de un substrato metálico no ferroso tal como aluminio con un agente activador ácido tal como HF seguido de tratamiento con un organofosfato y organofosfonato. El tratamiento proporciona una mejor adhesión y flexibilidad así como resistencia a la humedad, a la corrosión por pulverización salina y a los detergentes de los revestimientos posteriormente aplicados.
