Coatings surface cleaning properties

Mercury-plated electrodes. Platinum can be plated with mercury to form an electrode with many of the properties of a mercury surface. This is done by cleaning a platinum electrode in nitric acid, connecting it as the cathode in perchloric acid solution over a pool of mercury, and then dipping it into the mercury while it is still connected in the circuit. The method works well for plating a planar platinum inlay electrode to give a flat mercury-coated surface, but it can be used for electrodes of any shape.112... 

Water-borne fluoroalkylsilane systems make also permanent antigraffiti coatings possible. Nearly all paint systems and felt-tip markers can be removed without residue from protected surfaces with the aid of commercially available and environmentally friendly graffiti cleaners (Fig. 6). More than ten cleaning cycles are possible without a significant reduction in cleaning properties [15].
