    Abstract: A conversion coating that does not substantially diminish the luster of a metal surface on which it is coated nor impair adhesion to the surface of lacquers and printing inks commonly used on beverage containers may be provided by contacting the metal surface with an aqueous liquid composition comprising water and at least the following components: (A) a component of one or more dissolved transition metal compounds that contain zirconium and may also inlcude titanium, provided that zirconium constitutes more than 30 % of the moles of the total moles or zirconium and titanium; (B) a component of at least one dissolved compound that contains inorganically bonded fluorine and is not part of component (A); and (C) a component of dissolved organic polymer molecules.

    Abstract: An excellent lubricant and surface conditioner layer on formed metal surface s, particularly aluminum cans that have been previously provided with a chromium oxide conversion coating, can be formed by contacti ng the cans with an aqueous lubricant and surface conditioner forming composition that contains at least one oxa acid or methy l ester thereof corresponding to the general formula (I): CH3(CH2)n O(CH2CH2O)x CH2C(O)OR, where each of n and x, which may be the sam e or different, is a positive integer and R represents H or CH3 and at least 20 weight % of the total content corresponding to the general formula (I) does so when x is at least 8, and then drying the thus-treated cans.
