Characterization of Multilayered Automotive Paint Systems Including Depth Profiling and Interface Analysis
Design and development of today’s high performance, original equipment manufacturer (OEM) paints and coatings requires the ability to do surface and interface analysis, as well as depth profiling. Obtaining compositional information as a function of locus enables one to better understand the relationship of chemical functionality, component distribution, and network architecture to the product performance (i.e., chemical, physical, mechanical and appearance properties/durability). A multi-technique approach was found effective in providing the desired compositional information, combining infrared (IR), Raman, time-of-flight secondary ion mass spectrometry (ToF-SIMS), and tunneling electron microscopy (TEM) analyses. The complementary information resulting from these techniques gave a detailed view of coating system chemistry and morphology, including insights on service life prediction. This, in turn, offers feedback for optimizing system design with respect to material properties, environmental factors, material processing and application considerations.
