Acid-Driven Cleaning and Pretreatment - Passivation and Pretreatment of Aluminum, Galvanized and Stainless Steels

This two-part presentation begins with a thorough explanation of the concepts of passivation and pretreatment. Passivation of galvanized steel should not be confused for a pretreatment, because passivating actually inhibits paint adhesion, whereas pretreatments enhance paint adhesion. With a fullness of understanding of these concepts, the second part of the presentation focuses on the advantages of using acids for cleaning and preparing metals for painting. To comply with modern regulatory desires, the acid-driven reactions must be phosphate-free, heavy metal-free, and non-toxic. Combining an appropriately designed acidic cleaner and a passivator has been demonstrated to permit a significant increase in the amount of acid in the process, allowing up to 1000x higher concentrations of acids that would otherwise not be tolerated without in-process corrosion. The approach allows for a combined passivation and pretreatment of otherwise stubborn-to-treat metals.
