Abstract: The adhesion and/or corrosion resistance of a autodeposited coating can be improved by rinsing the uncured coating with an aqueous treatment solution that has a pH between 7 and 11 and contains between 0.05 and 5 w/o of anions derived from multifunctional organic acids, preferably anions of 1-hydroxyethylidene-1,1-diphosphonic acid, citric acid, tartaric acid, and/or oxalic acid. The method is particularly useful on leaf springs and other metallic objects with surfaces of high carbon and/or shot blasted steel, and is particularly useful in conjunction with an autodeposition bath containing internally stabilized poly {vinylidene chloride} latex, hydrofluoric acid, ferric fluoride, and hydrogen peroxide.

Abstract: Mixtures of light colored bis(C.sub.8 -C.sub.22 fatty acid) alkylene diamides, C.sub.8 -C.sub.22 fatty acid esters, and, if desired, metal soaps of C.sub.8 -C.sub.22 fatty acids can be obtained if, in a melt containing fatty acids with 8 to 22 carbon atoms, a part of the fatty acids are condensed to the corresponding fatty acid diamides with diamines of the general formula NH.sub.2 --R--NH.sub.2, in which R is a straight chain, branched, or cyclic alkylene group with 2 to 12 carbon atoms; a part of the fatty acids are esterified with fatty alcohols with 8 to 22 carbon atoms and/or multifunctional alkanols with 2 to 15 carbon atoms and 2 to 6 hydroxyl groups; and, if desired, a part of the fatty acids are converted to the corresponding metal soaps with basic compounds of divalent metals. The condensation with the diamines is carried out before the esterification of the fatty acids with fatty alcohols and/or multifunctional alkanols. The mixtures so obtained can be used as additives in plastics.

Abstract: A process for forming a chromium/silica/phosphate protective conversion coating on a metal surface is improved by pretreating the surface with a composition comprising at least one of (i) H.sub.2 TiF.sub.6, (ii) H.sub.2 SiF.sub.6, and (iii) a derivative of poly{alkenylphenol} before applying the conversion coating. The process of the invention results in a protective base coating having superior adhesion to paint at a relatively high coating weight which is desirable for improved corrosion resistance. This process is especially useful in forming such protective conversion coatings on continuous cast aluminum surfaces.

Abstract: In an industrial dishwasher a cleaning solution which is highly concentrated relative to the rinsing water is recirculated in a washing region over items to later be rinsed, whereby the cleaning solution is directed into a collector trough, where the level of the solution is maintained automatically through use of a metering tank juxtaposed to the collector trough, whereby the metering tank collects rinse water, and a non-return flap valve located between the collector trough and metering tank provides for rinse water to flow from the metering tank into the collector trough only at such times when the level of the cleaning solution in the collector trough is lower than the level of the rinse water in the metering tank at upper-most regions thereof.
