Abstract
The present invention provides a process for preparing metal particle-containing powder coating compositions as well as the powder coating compositions produced by this process. The process involves spraying a solution which comprises solvent, resin, curing agent, and suspended metal particles to form droplets, and collecting the sprayed droplets in a liquid bath. The liquid bath contains a liquid which is miscible with the solvent but which is non-solvent for the solutes of the solution. The liquid bath is subjected to a radial motion. Thus the powder coating compositions are precipitated in substantially non-agglomerated form. The resulting metal particle-containing powder coating compositions are useful in powder coating applications such as powder painting when it is desired to impart a metallic finish to an article such as an automobile. These powder coating compositions are particularly useful when it is desired to impart to a surface a thin film, such as a coil coating.
