Versatile Processes for Preparing and Using Novel Composite Particles in Powder Coating Compositions

摘要

A process for preparing particles of a powder coating composition is provided which comprising the steps of a) providing a first particle component comprising a plurality of first particles, wherein the first particles comprise a film forming resin; b) providing a second particle component comprising a plurality of second particles; c) mixing the first and second particle components to form a particle mixture; d) fluidizing the particle mixture in a gas flow; and e) subjecting the fluidized particle mixture to a heating event under conditions effective to provide a plurality of composite particles at a temperature greater than the temperature of the gas flow.
