The present invention provides a partially neutralized aqueous polyurethane dispersion (PUD) containing an amorphous polyester, wherein the dispersion is from about 70% to about 90% neutralized with a sterically hindered amine. The partially neutralized aqueous polyurethane dispersion (PUD) may be used to provide coatings, adhesives, sealants, paints, primers, and topcoats having excellent chemical resistance to aggressive chemicals such as isopropanol. |
