These plate shaped pigments (mica, glass flake, aluminum…) always arrange themselves in perfect horizontal planes in the example diagrams (fig. 2) to show the path barrier property. Do you have any e-microscope or real imaging that shows this is true? What force makes the plates lay flat in the curing film? I do believe the plate shaped particles will increase the barrier properties but I think it is likely due to random walls in the 3 dimensional matrix of the film. This would still create a longer path for water migration. I just take exception to the flat plate theory- that has been around for years.
What if the plates had a perpendicular orientation? Would they be a sliding highway for the water?
