I'll have to do some looking, but there is quite a bit of data on all kinds of cooling coils, such as radiators, A/C evaporators/condensers, industrial cooling systems, etc. The general consensus is even a layer a dust can reduce heat transfer. If the condenser coil on your house A/C gets too dirty, it makes a noticable difference to clean it off.

The whole theory of cooling relies on getting the heated air in contact with as much surface area as possible, then get the cooling air in contact with as much surface area as possible. The material between the two 'airs' needs to allow as much thermal transfer as possible, that's where guys like Secan have made the improvements. Any extra material is just an insulator and impedes thermal transfer. When you look at a 'price-no-object' Secan if they thought a coating would be of benefit, they would use one.
