Abstract
The bottom of a dip coating bath (5a) is perfluoro(methylcyclohexane), a dense, inert liquid. A much thinner layer of coating solution occupies the top (5b) of the bath. An aluminum drum (1) to be coated is moved into the bottom bath until the top of the drum is in the top of the bath. The drum is moved out of the bath and is coated by the top liquid. The amount of coating material used is greatly reduced and the inert liquid can be reused.
