ABSTRACT:
A process for forming curable powder comprises providing an aqueous dispersion of particles of curable resin and optionally particles comprising at least one curing agent; aggregating the particles optionally with the curing agent to form aggregated particles; coalescing the aggregated particles to form fused particles; and removing the fused particles from the aqueous dispersion. By this process, a curable powder is formed. The curable powder may be used in powder coating.
