    摘要: The invention relates to a process for the preparation of aqueous dispersions to be further processed to electrocoating paints with baking temperatures below 160.degree. C. and baking times.ltoreq.30 minutes, which dispersions contain modified epoxide-amine adducts as binders and polyisocyanates blocked by hydroxyl groups as cross-linking agents.In this process polyepoxides and compounds containing one or more, preferably 2, hydroxyl groups per molecule are reacted at elevated temperatures in the presence of catalysts to furnish epoxide-containing intermediates.A solvent or a mixture of solvents is then added with external cooling ahd the solution is boiled under reflux, if necessary in vacuo, until the temperature of the solution drops to 95.degree. C. to 20.degree. C.Amines are then added onto the epoxide groups which are still present in a free state in the epoxy resin and a dispersion is prepared by adding a water/acid mixture after adding the crosslinking agent or the dispersion is first prepared and the crosslinking agent is added subsequently.

    摘要: The invention relates to a process for the preparation of aqueous dispersions to be further processed to electrocoating paints with baking temperatures below 160° C. and baking times of ≦30 minutes, which dispersions contain modified epoxide-amine adducts as binders and polyisocyanates blocked by amino groups as crosslinking agents. In this process, polyepoxides and compounds which contain one or more, preferably 2, hydroxyl groups per molecule are converted at higher temperatures and in the presence of catalysts to epoxide-containing intermediates. A solvent or a mixture of solvents is then added with external cooling and the solution is then caused to boil under reflux, if necessary by application of a vacuum, until the temperature of the solution drops to 95° C. to 20° C. Amines are then added onto the epoxide groups which are still present in a free state in the epoxide resin and either a dispersion is prepared after the addition of the crosslinking agent by adding a water-acid mixture or the products are first dispersed and the crosslinking agent is added subsequently.

    摘要: The present invention relates to a process for the preparation of an aqueous coating composition containing a carboxyl-containing epoxy resin having an acid number in the range from 5 to 200 mg of KOH/g and having an epoxide equivalent weight in the range from 1000 to 40,000, optionally crosslinking agents, organic solvents, optionally conventional assistants and additives, and optionally pigments and fillers. The organic binder solution is neutralized using a tertiary amine in the temperature range from 60.degree. C. to 120.degree. C. This is followed by dispersion in water, with the proviso that at least 95% of the epoxide groups of the epoxy resin have been reacted. The aqueous coating compositions prepared by the process are preferably used for coating cans.
