    Abstract: The present invention relates to a method for coating a graphite heat dissipation sheet, comprising a step of coating the surface of a graphite sheet with a powder paint through electrostatic spraying, thereby forming a coating layer on the surface of graphite, wherein the powder paint comprises: 80-90 parts by weight of an epoxy resin consisting of 30-40 wt % of an o-cresol novolac epoxy resin with a softening point of 70-90° C. and 60-70 wt % of a bisphenol A epoxy resin with a softening point of 110-120° C.; 10-30 parts by weight of a polyester resin containing a carboxyl group at the terminal thereof; 0.1-5 parts by weight of a curing accelerator; and 20-30 parts by weight of a layered clay mineral.

    Abstract: In a powder coating process, a primer step is implemented prior to electrostatically applying the powder coating, either in advance of preheating the object to be coated or subsequent thereto, depending upon the selection of materials used in the object to be coated, the primer material being diluted fabric softener applied in a fine mist spray or fog to the object.

    Abstract: An electrostatic powdering robot for a powder booth, the robot including a projector for performing electrostatic powder coating. In order to reduce the time required for powder removal from the booth and facilitate automation of powder removal, the robot further includes a robotic arm, which is articulated and which carries the projector for positioning the projector, as well as a blower, for blowing a powder removal fluid, preferably air, the robotic arm carrying the blower to position the blower inside the booth, so that the blower blows the powder removal fluid onto a surface to be de-powdered inside the electrostatic powdering booth and thereby removes the residual powder coating the surface to be de-powdered.
