Abstract

L'invention concerne une combinaison d'acide organique bifonctionnelle (de préférence un acide hydroxy comme l'acide citrique ou un sel de cet acide) et de polymères à base d'acide acrylique/acrylate intégrée à des compositions liquides pour revêtement de conversion en phosphate de zinc (contenant de préférence également de l'hydroxylamine). Ce type de composition donne un revêtement à base de cristaux plus fins et/ou à formation plus rapide d'une couche de conversion suffisamment épaisse, en vue de protéger un substrat ferreux contre la rouille à laquelle il peut être exposé ultérieurement.
