Am. Twitchell et al., THE BEHAVIOR OF FILM COATING DROPLETS ON THEIR IMPINGEMENT ONTO UNCOATED AND COATED TABLETS, STP pharma sciences, 5(3), 1995, pp. 190-195
The behaviour of film coating solution droplets of varying viscosity a
nd momentum on uncoated and coated tablets have been determined and th
e role of droplet viscosity and momentum in determining the surface ro
ughness of coated tablets investigated. It is shown that the droplet v
iscosity and momentum are important in governing their spreading and p
enetration behaviour on uncoated and coated tablet surfaces and conseq
uently the formation, appearance and properties of the film.
