Abstract:
1. A continuous process for preparing a powder coating slurry or a powder coating material by emulsification of their constituents comprising (1) preparing at least one liquid component (A) comprising at least one binder in a reaction vessel by a method selected from the group consisting of continuous addition polymerization, polycondensation and combinations thereof, (2) discharging the liquid component (A) continuously from the reaction vessel and conveying it into a mixing unit in which it is mixed continuously with at least one liquid component (B) comprising at least one additional starting material of the powder slurry or powder coating material, to give a liquid component (C), and (3) conveying the liquid component (C) continuously into a dispersing unit in which it is emulsified in a continuously supplied aqueous medium (C), to give an aqueous emulsion (E) of liquid particles, and subsequently either preparing a powder slurry (F) by (4) cooling the emulsion (E), to form a suspension (F) of dimensionally stable particles, and or preparing a powder coating material (G) by (5) isolating the dimensionally stable particles directly from the aqueous emulsion (E) or the suspension (F).
