Abstract
A coated substrate, such as thick, coated metal sheet is made using a system (10) where a moving metal sheet substrate (12), preferably aluminum over 0.1 mm thick contacts an applicator roll (20) which has a non-deformable, micro-porous flat ceramic surface which is coated with a coating liquid (14) which is picked up, by a metering roll (18) and applied to the applicator roll (20) by contact with the coated metering roll, and where a backup roll (22) usually helps support the moving substrate.
Claims11
A method of coating a metal sheet substrate having a thickness greater than 0.1 mm comprising:
- (a) providing a continuously moving metal sheet substrate having a thickness greater than 0.1 mm;
- (b) providing a source of coating liquid;
- (c) applying the coating liquid to a micro-porous, flat, ceramic surfaced applicator roll;
- and
- (d) contacting the metal substrate with the coated, micro-porous, flat ceramic surfaced applicator roll, to coat the substrate.
