ELECTRODEPOSITION COATINGS INCLUDING A LANTHANIDE SERIES ELEMENT FOR USE OVER ALUMINUM SUBSTRATES |
摘要 |
A process for applying a coating on aluminum substrates by anionic or cationic electrodeposition of an electrodeposition coating including an aqueous dispersion of one or more lanthanide series elements having a +3/+4 oxidation state and phosphated epoxy resin made by phosphating a polyepoxide with both phosphoric acid and an organophosphonic acid and/or an organophosphinic acid. The coating has a reduced tendency to form pinholes. |
