Abstract
A method of improving the transfer efficiency of applying a topcoat layer to a primed component includes applying an organic solventborne, carboxyl functional olefin based polymer composition to a substrate to provide a primed component before electrostatically applying a coating composition comprising principal resin and crosslinker to the primed component to form a topcoat layer, wherein the carboxyl functional olefin based polymer is neutralized with at least one amine-containing compound to form a salted carboxyl functional polymer.

A method of improving the transfer efficiency of applying a topcoat layer to a primed component, the method comprising:
- applying an organic solventborne, carboxyl functional olefin based polymer composition to a substrate to provide a primed component, and
- electrostatically applying a coating composition comprising principal resin and crosslinker to the primed component to form a topcoat layer,
- wherein the carboxyl functional olefin based polymer is neutralized with at least one amine-containing compound to form a salted carboxyl functional polymer, wherein the amine-containing compound is selected from the group consisting of dimethylaminoethanol, aminomethylpropanol, and combinations thereof.
