Abstract
The waterborne coating composition herein is useful for promoting adhesion of paint to a component such as a plastic automobile part or accessory. The waterborne coating composition is particularly useful for promoting adhesion of paint to a thermoplastic polyolefin surface. The waterborne coating composition is prepared from a mixture comprising at least one chlorinated polyolefin resin and at least one urethane acrylic hybrid resin. The waterborne coating composition provides not only good adhesion of a paint to a thermoplastic polyolefin surface, but also provides good appearance. The waterborne coating composition is also compatible with a wide variety of paint systems and can be rapidly dried under ambient conditions.
