AQUADAG is used in CRO for the collection of secondary electrons emitted from the inner CRT tube surface.
It is actually a graphite(mild) coating on the inner side of CRT side walls for collecting secondary electrons so that the CRT do not get heated up due to the Collisions of those electrons at some other parts of CRT, there by preventing CRT from Thermal Runaway.

The purpose of graphite coating called Aquadag coating is to absorb all the electrons that get diverted from their path while they are travelling coaxial to the CRT. These electrons are attracted towards the aquadag coating and returned to the anode accelerating anode.
This is unknown.
