Coating Window for Double Layer Extrusion Slot Coating of Poly(Vinyl-Alcohol) Solutions

摘要

The expansion of coating windows for low-viscosity poly(vinyl-alcohol) (PVA) solutions is achieved via utilization of a higher viscosity PVA solution as the stabilizing carrier layer.;;The expansion of coating windows for low-viscosity poly(vinyl-alcohol) (PVA) solutions is achieved via utilization of a higher viscosity PVA solution as the stabilizing carrier layer.
