Abstract

The invention provides a method of creating a material for use as a material to be coated by curtain coating, comprising the step of: creating a surface texture of said material such that when said material is coated with a freely falling curtain formed of a composite layer of one or more coating compositions that impinges at a point of impingement against a continuously moving receiving surface of said material using roughness assisted wetting, the height of the composite layer at a distance &lgr; from the point of impingement, in which &lgr; is the average periodicity of the surface texture, is less than or equal to Rz. The invention also provides a method of identifying a material suitable for coating with Roughness Assisted coating.
