A process for forming a two-coat electrodeposited composite coating, the composite coating and chip resistant electrodeposited coating composition

A process for forming a two-coat electrodeposited composite coating, the composite coating and chip resistant electrodeposited coating composition

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 provi...

Beschreibung
Zusammenfassung: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.
