Abstract: A composition and process for treating ferrous substrates including black plate container bodies to inhibit in-process corrosion or rusting of the surfaces thereof by contacting the ferrous substrate with aqueous acidic composition containing controlled effective amounts of aluminum, fluoride, optionally a second metal selected from the group consisting of zirconium, titanium, hafnium and mixtures thereof and hydrogen ions to provide a pH on the acid side.

Abstract: A process for treating food and beverage containers comprised of low-carbon steel sheet (black plate) to improve the adherence and to resist undercutting of organic can lacquers applied to the surfaces thereof when subjected to agressive environments without visually impairing the light-grey shiny steel appearance of the container surface and without loss of humidity resistance. The treatment can readily be integrated with conventional can body manufacturing procedures and includes contacting the cleaned black plate container body surface with an aqueous acidic solution containing a controlled amount of stannous ions at a controlled temperature for a period of time sufficient to deposit tin on the surfaces thereof in an amount up to about 5 mg/ft.sup.2 followed by rinsing, drying and lacquering.

Abstract: Disclosed is a one package cleaning solution replenisher concentrate having good temperature stability characteristics. The replenisher concentrate is a temperature stable aqueous acidic solution comprising a polyalkylene glycol-abietic acid surfactant, a polyalkylene glycol-hydrocarbon surfactant, and at least 2% fluoride and is well adapted to replenish a working bath of cleaning solution to maintain the activity thereof.

Abstract: A composition and a method for applying a lubricant coating to clean metal surfaces prior to subjecting them to metal forming operations. The composition comprises a concentrate which is adapted to be diluted with water, if desired, to produce an aqueous acidic operating bath containing a controlled effective amount of phosphate ions to form a phosphate coating on the clean metal surface in combination with an emulsified organic lubricant agent, an emulsifying agent and an iron chelating agent. The coating composition may further optionally contain a controlled amount of a corrosion inhibiting agent and heavy metal cations for activating the coating bath. The coating composition is applied to a clean metal surface such as by flooding, immersion, spraying, or the like, at temperatures from ambient up to about 200.degree. F. for a period of time sufficient to effect a desired coating magnitude whereafter the parts are dried, preferably at elevated temperatures before forming.

Abstract: Disclosed are a composition and process useful for the treatment of an aluminum surface comprising contacting the surface with an aqueous solution containing at least 0.000025 weight percent of a vegetable tannin, which solution exhibits a pH of at least 3. Best results can be obtained via a two-stage tanin treatment in which the treating solution of the first stage also contains titanium and fluoride in dissolved form.

Abstract: Aluminum surfaces are cleaned at low temperature by the addition of a polyalkylene glycol-abietic acid surfactant and a polyalkylene glycol-hydrocarbon surfactant to an aqueous acidic solution. Preferably, the solution contains fluoride as an accelerator.
