Disclosed are methods for treating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods include depositing an electropositive metal onto at least a portion of the substrate, and then contacting the substrate with a pretreatment composition that is substantially free of crystalline phosphates and chromates. The present invention also relates to coated substrates produced thereby.

Methods for coating a metal substrate and related coated metal substrates

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.

Electrodeposition coatings including a lanthanide series element for use over aluminum substrates

A barrier coating comprising a polyurethane dispersion and an elastomeric material is disclosed. The polyurethane comprises at least 30 weight percent of meta-substituted aromatic material. Methods for improving barrier using the coatings are also disclosed.

Barrier coating comprising a polyurethane dispersion and elastomeric material

Disclosed are methods for passivating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods comprise the steps of depositing an electropositive metal onto at least a portion of the substrate, followed immediately by electrophoretically depositing on the substrate a curable, electrodepositable coating composition. The present invention also relates to coated substrates produced by the above methods.
