Acid cleaning/pickling compositions for metal surfaces containing (A) at least one protein-derived polymer, sugar-derived polymer, sorbitol, tannin, or vinyl-based polymer, (B) at least one iodine or iodine-affording compound; acids solutions prepared therefrom; and methods for their use.

Non-toxic acid cleaner corrosion inhibitors

An activator composition having increased effectiveness and life when used in an aqueous alkaline stripper solution at elevated temperatures to remove siccative coatings from substrates containing two essential components A and B. Component A consists essentially of at least one of an ethoxylated tetrahydrofurfuryl, a mixture of an ethoxylated tetrahydrofurfuryl and an ethoxylated furfuryl, N-methyl-2-pyrrolidone and N-(2-hydroxyethyl)-2-pyrrolidine. Component B consists essentially of at least one of N-phenyl-diethanolamine, furfurylamine, tetrahydrofurfurylamine, octadecylamine, butoxypropanolamine and N-amino-morpholine.

Activator-accelerator mixtures for alkaline paint stripper compositions

Aqueous copper coating compositions, solid compositions for forming the aqueous compositions, and processes for coating the surfaces of ferrous-containing materials by contacting said surfaces with the aqueous copper coating compositions, wherein the aqueous compositions contain:

Compositions and processes for coating ferrous surfaces with copper

An aqueous alkaline composition having increased effectiveness and bath life when used at elevated temperatures to remove siccative coatings from substrates coated therewith containing one or more alkaline compounds and at least two of the following three materials: tetrahydrofurfuryl alcohol, an ethoxylated furfuryl alcohol and an ethoxylated tetrahydrofurfuryl alcohol; and preferably containing one or more of a sequestering agent, a composition-stabilizing compound, and a surfactant.
