Described herein is a powder coating that includes a plurality of particles. The plurality of particles includes amorphous polyester and iron oxide pigment, wherein the plurality of particles have a size of from 5 microns to 250 microns, and wherein the plurality of particles each have a circularity of from about 0.93 to about 0.999. A method of manufacturing the particles is also disclosed. Il est décrit un revêtement en poudre qui comprend une pluralité de particules. La pluralité de particules comprend un polyester amorphe et un pigment doxyde de fer, chaque particule de la pluralité ayant une taille de 5 à 250 microns, et chaque particule de la pluralité ayant une circularité denviron 0,930 à environ 0,999. Il est également décrit un procédé de fabrication des particules.
