Abstract

Une solution aqueuse de manganèse, de phosphate et d'acide phosphorique, contenant de préférence peu ou pas de substance qualifiée conventionnellement d'accélérateur ou d'ions métalliques divalents autres que le manganèse et le fer, forme une couche de conversion du phosphate de bonne qualité pour sous-couche de peinture sur des substrats métalliques, surtout ceux d'acier et d'acier galvanisé, lorsqu'elle est mise en contact par aspersion ou immersion avec ces substrats à une température de 54 à 65 DEG C pendant 0,5 à 5 minutes.
