(57) [Summary]nLubricating surface modifiers which reduce the coefficient of static friction of the surfaces of metal moldings, in particular aluminum and tin beverage cans, and make it possible to dry said surfaces at lower temperatures, the modifier being (i) an amine. Oxides and quaternary ammonium salts, ethoxylated castor oil derivatives, imidazoline group-containing phosphonates, and preferably (ii) one or more of fluozirconate, fluohafnate, fluotitanic acid, and (iii) phosphoric acid and Treated containers containing / or nitrate ions have a good resistance to the friction-reducing effect being impaired when overheated and to the blackening of the can bottom due to sterilization. |
