  • ELECTROCOATING COMPOSITION
    Publication number: 20210269667
    Abstract: Cathodic electrocoating composition with improved edge protection and coating appearance are provided. An exemplary cathodic electrocoating composition includes an aqueous carrier, a film forming binder dispersed in the carrier and including an epoxy-amine adduct and a blocked polyisocyanate crosslinking agent; a pigment paste; a water-soluble cellulose ether; and a cationic microgel dispersion which is prepared by a process comprising dispersing in aqueous medium a mixture of a cationic polyepoxide-amine reaction product which contains amine groups selected from the group consisting of primary amine groups, secondary amine groups, and mixtures thereof and a polyepoxide crosslinking agent and heating the mixture to a temperature sufficient to crosslink the mixture to form the cationic microgel dispersion. The water-soluble cellulose ether may be hydroxyethyl cellulose.
