Primäre Aminogruppen enthaltende Dispergiermittel für Pigmente zur Verwendung in kathodischen Elektrotauch-Zusammensetzungen

摘要

A compound that is useful as a dispersant for pigments in waterborne coating compositions, particularly in cathodic electrocoat compositions, is described. The compound comprises an acrylic backbone having a pigment-interactive substituent and a stabilizing substituent. The pigment-interactive substituent has at least one primary amino group. The stabilizing substituent comprises an alkoxy-terminated polyalkylene oxide structure. The dispersant is useful in preparing electrocoat coating compositions.
