  • Coating processes
    Patent number: 5391401
    Abstract: In curtain coating, uniform layer or layers are only obtained if the operational variables are held within precise limits. These limits define a "coating window". However, one of the boundaries of this "window" is governed by the occurrence of air-entrainment. Described herein is an improved coating process in which allows the "coating window" to be enlarged. This is achieved by using a material adjacent the support on to which the liquid material is to be coated which readily shear-thins.
