A process for producing a powder coating composition having powder particles wherein at least 50% of the particles are of a size between 3 and 5 microns and 100% of the particles are of a size </=10 microns. The process includes the steps of preparing a powder coating extrudate, reducing the extrudate to flake, jet milling the powder coating to a powder wherein at least 50% of the particles are a particle size of between 3 and 5 microns and 100% of the particles are of a size less than or equal to 10 microns, and adding the powder to a mixture of water and surfactant. Dispersant and rheology control agents are then added to the mixture. |
