Method and use of a binder for providing a metallic coat covering a surface |
摘要 |
A method for providing a metallic coat covering a surface is disclosed, which comprises: (i) applying an electrically conductive two component binder on said surface; (ii) electrostatic spraying a metal powder on the binder applied in step (i); wherein the metal powder comprises metal particles with an average diameter less than 80 micron. |

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. |
