Abstract: A method of producing a coating composition containing flake-like, color effect pigment particles and polymeric binder. The pigment composition has an initial size with fine particles. Upon mixing and heating the pigment composition to a temperature to achieve a second particle size distribution, the fine particles in the initial particle size distribution are bound to the larger particles in the pigment composition. The time and temperature of bonding the pigment composition can be adjusted to account for the chemistry of the polymeric binder and the loading of the flake-like, color effect pigment.

Abstract: Disclosed are methods of dispensing thermoset powder coating compositions comprising a colorant, a particulate film-forming resin, and a curing agent for the film-forming resin, methods of coating substrates with powder coating compositions dispensed according to such methods, and systems for dispensing such powder compositions.

Abstract: An extrusion process for manufacturing powder coating compositions is disclosed. The process generally includes a shear mixing step done at ambient temperature and a focused heating step in which the shear mix is heated to a higher temperature for a shorter time than in conventional methods. The focused heating provides for a shorter heat history, resulting in enhanced coating properties. The mixture may be cooled before it leaves the extruder.

Abstract: A transportable container for fluidizable solids includes a storage container adapted to contain the fluidizable solids is disclosed. The storage container defines an air inlet port for introducing fluidizing air into the storage container and a solids outlet port for discharging the solids from the storage container. A solids outlet conduit may be connected to the solids outlet port for supplying the solids to a downstream process or apparatus. An agitator is provided at the bottom end of the storage container for mixing and maintaining homogeneity of the solids in the fluidizing air. A fluid permeable fluidization membrane is disposed in the storage container below the agitator. The fluidization membrane defines an air chamber below the solids for introducing the fluidizing air into the solids.
