<p>This invention provides a method for preparing a powder coating composition having a particle size of from about 0.5 to 40 microns. Such compositions are especially useful in applications where a thin film (i.e., about 0.1 to 1.0 mil) is desired as well as applications where highly thermally reactive compositions are utilized. Optionally, the small particles are then pelletized and reground in a hammer-type mill to afford a composition having a particle size of approximately 30-40 microns. The method is especially useful for compositions which are designed to cure at a temperature at or below conventional extrusion temperatures, i.e., 90-130 °C.</p> |
