Abstract
It has now been determined that a first coating layer may be applied to a substrate by a first coating die in a much thinner layer than its rheological properties and/or surface properties would normally allow. This is accomplished by using a second coating fluid dispensed from a second coating die acting as a 'dynamic liquid squeegee' to transport, spread, even, or meter the first coating layer on the substrate by varying a gap between the second coating die and the substrate.
