    摘要： A finishing agent satisfies a condition that (A) the ratio of the chromium equivalent molar concentration of a water-soluble trivalent chromium-containing substance contained in the finishing agent relative to the phosphorus equivalent molar concentration of a water-soluble phosphoric acid-based compound contained in the finishing agent is 0.5 or more, or a condition that (B) a water-soluble aluminum-containing substance and/or a water-soluble zirconium-containing substance are contained in the finishing agent such that the ratio of the total of the chromium equivalent molar concentration of the water-soluble trivalent chromium-containing substance, the aluminum equivalent molar concentration of the water-soluble aluminum-containing substance, and the zirconium equivalent molar concentration of the water-soluble zirconium-containing substance relative to the phosphorus equivalent molar concentration of the water-soluble phosphoric acid-based compound is 0.5 or more.

    摘要： Aqueous compositions useful as pretreatments prior to painting and to reduce the formation of rust in the uncoated condition consist essentially of water, an organo-functional silane, a compound of a Group IV-B element, and optionally a polyvinyl alcohol, stabilizing agents, wetting agents, thickeners, and biocides, and have an alkaline pH>7. A process for treating a metal surface includes contacting the surface with such an aqueous composition. The compositions and processes were found to have further benefits in comparison to the zinc phosphate metal pretreatment thought to be the standard in the industry. Preferably, the pH of the compositions is alkaline, which has been found to improve the efficacy of a silane as a surface treatment to improve uniformity of paint adhesion. By operating in the alkaline pH range, it was found that flash rusting and/or blush rust were significantly reduced.

    摘要： A method of coloring the surface of a tin-containing article is provided, the method comprising contacting at least a portion of the surface of the article with a solution comprising a thiosulphate, preferably under substantially neutral or acidic conditions. In one embodiment, the solution contains sodium thiosulphate and citric acid and further comprises a copper salt, together with acetone and/or glycerol. The method is preferably conducted at elevated temperatures, in particular by heating the solution to a temperature of from 45 to 85° C. The method is particularly suitable for the coloring of pewter articles, but may be applied to a wide range of tin-containing materials and tin alloys.
