摘要： The present invention relates to an aqueous dispersion comprising - a base-neutralized resinous composition containing an ungelled phosphated epoxy resin (a) in which the phosphated epoxy resin comprises a mixture of the reaction product of one or more polymeric epoxy compounds with phosphoric acid and with an organophosphonic acid and/or an organophosphinic acid; - a curing agent (b), whereby (a) the phosphated epoxy resin is present in amounts of 50 to 90 percent by weight and (b) the curing agent is present in amounts of 10 to 50 percent by weight, the percentages being based on total solids weight of (a) and (b); and - an azole and to the use of the aqueous dispersion in a process for providing a coating on an aluminum substrate by passing electric current between the substrate acting as an anode and a cathode in electrical contact with an electrodeposition bath containing said aqueous dispersion.

摘要： A process for applying two electrodeposited coatings, one on top of the other, to an electrically conductive substrate is provided. An electrically conductive first coating is applied to provide for corrosion resistance and a second polyurethane-based coating is applied to the first coating to provide chip resistance. Also, aqueous dispersions of the polyurethane coating compositions are disclosed.

摘要： The present invention is directed to an electrodepositable composition of a resinous phase dispersed in an aqueous medium. The resinous phase includes an ionic polyester polymer prepared from a) an aromatic and/or cycloaliphatic carboxylic acid compound having at least two aromatic and/or secondary aliphatic carboxyl groups, b) a branched aliphatic, cycloaliphatic or araliphatic compound containing at least two aliphatic hydroxyl groups, the aliphatic hydroxyl groups being either secondary or tertiary hydroxyl groups or primary hydroxyl groups attached to a carbon adjacent to a tertiary or quaternary carbon, c) a compound including an ionic salt group or a group which is converted to an ionic salt group, and d) optionally, at least one hydroxyl substituted carboxylic compound comprising at least one tertiary aliphatic carboxyl group and at least two aliphatic hydroxyl groups. The present invention also includes a method for electrocoating a conductive substrate with the described electrodepositable composition. Lastly, the present invention is directed to a conductive substrate coated according to the described method.
