Abstract:
1. A method for providing a metallic coat covering on a surface, comprising: (a) applying a primer to a surface to create a primer layer; (b) airlessly spraying an electrically conductive two component binder onto the primer layer to create a conductive layer, wherein the two components are mixed in a nozzle of a spray device and are comprised of a polymer selected from the group consisting of polyurethane and polyurea and between 0.2% and 10% (W/W) quarternary nitrogen compounds; and (c) electrostatically spraying a metal powder onto the conductive layer, wherein the metal powder comprises metal particles having an average diameter in a range of from 2 microns to 55 microns; and (d) polishing the surface wherein the surface is selected from the group consisting of a circuit board, a roof and a panel.
