Abstract
Official abstract text for this publication.
An aqueous electrodeposition coating composition comprising (a) a metal oxide selected from the group consisting of bismuth oxide, vanadium oxide, manganese oxide, cobalt oxide, zinc oxide, strontium oxide, yttrium oxide, molybdenum oxide, zirconium oxide, lanthanum oxide, oxides of the lanthanide series of elements, and combinations of these and (b) a cathodically electrodepositable binder, the binder comprising an amine-functional phosphorylated resin, provides corrosion protection equivalent to that obtained by the conventional phosphate pretreatment-electrodeposition coating process.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous, cathodically electrodepositable coating composition comprising: a cathodically electrodepositable binder comprising: a resin component comprising: an amine-functional phosphorylated resin comprising at least one of a diphosphate ester of a polyepoxide resin, a triphosphate ester of a polyepoxide resin, and a diphosphonic acid ester of a polyepoxide resin; and a second amine-functional resin that is free from a phosphorous-containing group; an…
