A lubricant and surface conditioner for formed metal surfaces, particularly aluminum and tin beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. The conditioner includes (i) a water-soluble organic material selected from amine oxides and quaternary ammonium salts, ethoxylated castor oil derivatives, and imidazoline moiety-containing phosphonates and preferably also includes (ii) at least one of fluozirconate, fluohafnate, or fluotitanate ion, and (iii) phosphate and/or nitrate ions. Good resistance to damaging the friction reducing effect by overheating and to staining of the domes of treated containers during pasteurization can be achieved.
Un agent de conditionnement/lubrifiant pour les surfaces métalliques formées, en particulier pour des récipients en aluminium ou en fer blanc, diminue le coefficient de friction statique desdites surfaces métalliques et permet de les sécher à une température plus basse. L'agent de conditionnement contient: (i) un composé organique hydrosoluble choisi parmi les oxydes d'amines et les sels d'ammonium quaternaire, les dérivés éthoxylés de l'huile de ricin et des phosphonates contenant des fractions imidazoline; de préférence (ii) au moins un des ions fluorozirconate, fluorohafnate et fluorotitanate; et (iii) des ions phosphate et/ou nitrate. On obtient ainsi une bonne résistance aux effets néfastes des températures élevées sur la friction et au maculage des opercules des récipients traités, durant la pasteurisation.
