The results of experimental and theoretical studies indicate the possibility of solving the stability and reproducibility problem of the structure of thin, thick and coatings on the basis of the unique property of cohesive forces in the laminar flow of liquid at a Reynolds number of approximately 6.3 to carry the molecules of liquid particles of the flow to the surface of the boundary layer in the capillary-slit substrates.
