Abstract
Pseudo-paint films containing the same proportion of powder components as powder pressed films displayed different transient behaviors but similar steady-state photo-activities, regardless the presence of organic components such as the binder. This was assigned to the photo-erosion of a significant fraction of the organic paint components during the transient period. Therefore, after reaching steady-state, NO photooxidation could proceed freely as if only inorganic paint components were present. An average of ca. 25Â wt.% of organic phase erosion was observed but more severe erosion should occur closer to the top of the paint film.
