  • Publication number: 20080233356
    Abstract: A roll coating method for preparing a coated substrate with structured surface of the coating is described. Said method comprises application of a polymer based coating fluid to a substrate surface by means of a coating fluid application roll and then curing the applied coating, wherein the polymer based coating fluid is a fluid showing Bingham or Herschel-Bulkley flow behavior with a yield stress ?0>10 dyn cm?2, in particular a fluid having low viscosity at high shear rate, fast viscosity enhancement in the absence of shear stress and a high yield stress. Applications of such produced surfaces are release films, e.g. for pressure sensitive adhesives, controlled release adhesives and self-cleaning surfaces and friction coefficient reducing surfaces.
