    摘要： Provided is an electrodepositable coating composition of a resinous phase dispersed in an aqueous medium, the resinous phase including (a) an active hydrogen-containing, cationic salt group-containing resin; and (b) an at least partially blocked polyisocyanate curing agent. The composition contains an organotin catalyst which is or is derived from a dialkyltin compound having the structure (I): [R1][R2]—Sn═O  (I) where R1 and R2 are the same or different, and each independently represents a monovalent hydrocarbon group wherein the sum of the carbon atoms in R1 and R2 is greater than 8. The catalyst is present in an amount sufficient to effect cure at a temperature at or below 340° F. (171.1° C.). Methods of preparing and using the composition also are provided.

    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.
