Tuning roughness and gloss of powder coating paint by encapsulating the coating particles with thin Al2O3 films

In this work, we report a method to change the surface finish of a standard polyester-based powder coating paint, from gloss to matt, by depositing ultrathin films of Al2O3 on the powder coating particles. The coating experiments were performed in a fluidized bed reactor at 1bar and 27°C, using a ga...
