Title (EN) CORROSION INHIBITOR FOR MG AND MG-ALLOYS
(FR) INHIBITEUR DE CORROSION POUR MG ET ALLIAGES DE MG
Abstract: front page image
(EN)The invention disclosed is a composition for inhibiting the corrosion of a magnesium or magnesium alloy object in an aqueous media e g an aqueous solution containing halide ions e g chloride ions, up to their solubility limit, and in seawater The composition can also be used for inhibiting the corrosion of magnesium or magnesium alloys in engine coolants The composition comprising a hydrolysed silane e g bis- silane, an aqueous solvent, and an emulsifing agent.
(FR)L'invention porte sur une composition pour inhiber la corrosion d'un objet en magnésium ou en alliage de magnésium dans un milieu aqueux, par exemple une solution aqueuse contenant des ions halogénures, par exemple des ions chlorures, jusqu'à leur limite de solubilité, et dans de l'eau de mer. La composition peut également être utilisée pour inhiber la corrosion de magnésium ou d'alliages de magnésium dans des liquides de refroidissement de moteur. La composition comporte un silane hydrolysé, par exemple un bis-silane, un solvant aqueux et un agent émulsifiant.
