Abstract
The present invention pertains to a process for forming a coating on a substrate using a tribo-charging electrostatic fluidized bed process; characterized in that a powder coating is used which has a particle size distribution such that a) d(v,90)≦42.5 μm, and b) i) the percentage of particles <10 μm in size is ≦12% by volume, and/or ii) [d(s,90)÷d(s,10)]2≦3.5, [d(s,90)−7]d(s,90) being greater than 7 μm and d(s,90) and d(s,10) being measured in microns.
