    Abstract: A method for rendering uniform a coating applied to a substate is provided which redistributes a flowable non-uniformly applied coating with electrostatic forces after the coating has been deposited and before it solidifies. An electrostatic charging station charges the coating which, in the illustrated embodiment, is an insulative dip coating on a running length of rectangular conductive wire, as the wire emerges from a coating tank. The charged coating is passed to a coating redistribution station where shaped charged electrodes positioned to coincide with geometric high or low prints on the wire surface attract or repel coating material to cause it to flow from the more thickly to the more thinly coated regions. The redistributed coating is then dried at a drier station.

    Abstract: Multicolored tone paint compositions containing flat metallic particles are produced by subjecting an electrically conductive substrate coated with the paint composition, while wet, to ion current. The field caused by the corona current vertically orients the metallic particles in that portion of the paint subjected to the current while the metallic particles in the unexposed paint remain in horizontal orientation.

    Abstract: A method for activating an exposed layer of a structure including a provision of a structure including an exposed layer, and before or after the provision of the structure, a deposition in the reaction chamber of a layer based on a material of chemical formula CxHyFz, at least x and z being non-zero. The method further includes a treatment, in the presence of the structure, of the layer based on a material of chemical formula CxHyFz by an activation plasma based on at least one from among oxygen and nitrogen. The treatment by the activation plasma is configured to consume at least partially the layer based on the material of chemical formula CxHyFz so as to activate the exposed layer of the structure.
