The effects of weakly acidic remover( p H = 5),weakly alkaline remover( p H = 8) and alkaline remover( p H = 10)on removal of paint on 7 series aluminium alloys were investigated. The aluminium alloy was coated with phosphide primer,epoxy primer and polyurethane topcoat. The results showed that the removal time was shorter for weakly acidic remover than those for weakly alkaline and alkaline removers. Weakly alkaline remover functioned better in removing the paint. The immersion tests indicated that weakly ...
