  • Waterborne coating compostion and process of producing a film having improved adhesion on a substrate
    Publication number: 20030008079
    Abstract: A waterborne coating composition and a process of producing a film having improved adhesion on a substrate are disclosed. The waterborne coating composition, preferably a waterborne basecoat, includes a first component and a second component. The first component includes a solvent-based polyurethane and a neutralizing agent, preferably an amine. The polyurethane has hydroxyl functional groups and acid functional groups. The amine neutralizes the acid functional groups. As a result, an ammonium ion and a salt of the polyurethane are formed. The salt of the polyurethane, including a carboxylate ion, establishes dispersibility of the polyurethane in water. The second component includes a water-based epoxy resin. The water-based epoxy resin is substantially free of co-solvents and includes an epoxide group that is reactive with the ammonium ion.
