摘要:
A process is disclosed for forming a coating from a flocculating coating composition containing pigment particles dispersed in a solution of a film forming binder dissolved in a fugitive liquid carrier, maintaining the coating composition in average shear conditions of at least about 10 reciprocal seconds while transporting the coating composition through an inlet (52) of an extrusion die (50), through a manifold (54) of the die (50), through an extrusion slot of the extrusion die (50) and onto a substrate to form a coating layer on the substrate, and rapidly removing the fugitive liquid from the coating while maintaining the coating composition in the coating layer in an undisturbed condition until the coating solidifies.
