Powder Coating on Aluzinc: Positive Feasible Pretreatment Guide

Summary for powder coating on aluzinc Discussion

Powder coating on Aluzinc sheets is presented as feasible, though the answerer advises checking first with the Aluzinc supplier. In response to Siva Sivaraja Sekhar’s question from Chennai about whether the coating can be applied and what method to use, the reply says there is no obvious reason powder coating would be inappropriate. For pretreatment, the answerer notes that zinc phosphate should be workable, but says suppliers who disclose their process appear to use chromate conversion coating instead. That is described as sounding ideal for a material with high aluminum content like Aluzinc. The thread does not report any conflicting opinions or detailed process steps, so the guidance is limited to feasibility and likely pretreatment choices rather than a full production recipe.
