Mica pigment particles for powder coating applications

A mica-containing pigment composition, comprising:

• spherical pigment particles having glosses in a range of about 10 GU (Gloss Unit) to 70 GU, wherein the glosses reflect light in a specular direction, the pigment particles comprising a polymer material with mica flakes incorporated therein and thereon, the mica flakes comprising mica particles, wherein a diameter of the mica particles is between 5 μm and 200 μm and a thickness with a dimension below 1 μm, wherein the spherical pigment particles of the composition have a circularity of between about 0.93 and about 0.999 and a particle size distribution of between about 1.3 and about 2.0, wherein the circularity refers to a circumference of a circle of an equivalent area divided by an actual perimeter of a central cross-section of a particle, wherein a polyester is used in a production of the mica-containing pigment composition, the polyester comprising a polyester resin, wherein the polymer material comprises a water-soluble polymer that comprises a polymeric stabilizer used for the production of the mica-containing pigment composition, the polymeric stabilizer initially combined with the mica particles and the polyester resin as a part of the production of the mica-containing pigment composition, wherein the polyester resin and the polymeric stabilizer are then dissolved into a water-miscible organic solvent with the mica particles to form a fluid mixture that includes the mica particles, wherein a polar solvent is then added to the fluid mixture at a predetermined rate, wherein pigment particles then precipitate from the fluid mixture as a part of the production of the mica-containing pigment composition and wherein the polar solvent is used as an antisolvent to induce precipitation of mica pigment comprising the mica particles from the fluid mixture.
