Abstract
The present invention relates to a process for producing a coated product comprising: (a) coating a substrate with a coating material to form a coated substrate; and (b) stabilizing the coated substrate to form the coated product; wherein the operating parameter of substrate-substrate contact and coated substrate-coated substrate contact differs between step a) and step b), such that in step b) the contact is minimized. An apparatus is also provided.
Claims25
A process for producing a coated product in a rotating drum, the process comprising the steps of:
- a) coating a substrate with a coating material in a coating zone of the rotating drum rotating at a first circumferential drum speed to form a coated substrate;
- and
- b) stabilizing the coated substrate in a stabilization zone of the rotating drum rotating at a second circumferential speed to form the coated product;
- wherein the first circumferential drum speed is sustained in the range of from about 14 meter per minute to about 40 meter per minute and the second circumferential drum speed is sustained in the range of from about 10% to about 80% of the first circumferential drum speed for a duration of between about 0.5 minutes to about 20 minutes.
