Abstract
A process for preparing an aqueous powder coating dispersion comprising components A and B, wherein component A is a binder resin or a mixture of binder resins and component B is a crosslinker or a mixture of crosslinkers or component A is a crosslinker or a mixture of crosslinkers and component B is a binder resin or a mixture of binder resins, wherein the process comprises the steps of: a) dispersing a composition comprising component A by the addition of an aqueous medium in a phase inversion emulsification process, b) adding component B simultaneously with or after the addition of the aqueous medium, and c) optionally mixing the obtained composition to obtain a dispersion comprising components A and B. The process enables the preparation of stable powder coating slurries with particles in the range from 50 to 800 nm.
