摘要: A solid object can be coated by a nonwetting liquid since receding contact line cannot exceed critical speed. In this Letter we study the dynamical wetting transition at which film gets deposited withdrawing vertical plate out of reservoir. It has recently been predicted that is with diverging time scales and coincides disappearance stationary menisci. We demonstrate experimentally theoretically due to formation solitary wave, well below point. As consequence, relaxation times remain finite threshold. The structure on involves capillary ridge does not trivially match Landau-Levich film.
