      The article addresses that. It is because ceramics are durable while paints and coatings are not.

      Most coatings like paint that have this effect include ceramics to do most of the reflection, but the other paint stuff the ceramic substrate is emulsified in does not have near the reflectivity, so you’re impairing yourself if reflectivity/heat rejection is the only goal.
