A comparative study was conducted using newly developed non-polar olefinic white and the polar conventional paint systems. Test panels were prepared using two metallocene plastomers and two ethylene-propylene rubbers in a common polypropylene substrate resin. Paint integrity was evaluated under several test conditions using Ford STATRAM. The olefinic white paint provided excellent paint adhesion for both metallocene plastomer based TPOs. No paint peeling was observed under any of the test conditions. Low voltage scanning electron microscopy revealed extremely fine dispersion of the ethylene-butene plastomer at and near the TPO surface, which explains its excellent paintability.
