(FR) REVETEMENTS EN SILANE MELANGE
Abstract: front page image
(EN)A method of treating a metal surface for corrosion-inhibition thereof, by application of a solution containing at least one vinyl silane and at least one bis-silyl aminosilane and an aqueous composition solution having at least one vinyl silane and at least one bis-silyl aminosilane is also provided, along with a silane coated metal surface, wherein said vinyl silane and said bis-silyl aminosilane are partially or completely hydralized. Preferred vinyl silanes include vinyltriacetoxysilane, vinyltrimethoxysilane and vinylthriethoxysilane, used in combination with preferably bis- (trimethoxysilylpropyl)amine or bis- (triethoxysilylpropyl)amine. Said metal surface may comprise steel, aluminium and Al-alloys, zinc and Zn-alloys, magnesium, copper, tin and alloys, in particular hot-dip galvanized steel, zinc sheet, steel sheet and aluminium sheet.
(FR)L'invention concerne un procédé de traitement d'une surface métallique par application d'une solution contenant au moins un silane de vinyle et au moins un aminosilane bis-silyle. Cette invention a également trait à une composition renfermant au moins un silane de vinyle et au moins un aminosilane bis-silyle, et à une surface métallique recouverte de silane.
