ABSTRACT:
Powder coating materials preparable by(1) mixing at least two liquid components comprising in each case at least one liquid starting product in a static mixer, to give a molecularly disperse and/or finely dispersed liquid mixture,(2) emulsifying the liquid mixture (1) in an aqueous medium in a dispersing unit, to give an aqueous emulsion of liquid particles,(3) cooling the emulsion (2) so that a suspension of dimensionally stable particles is formed,(4) isolating the dimensionally stable particles from the suspension (3)or alternatively(3) isolating the dimensionally stable particles directly from the emulsion (2);and also processes for preparing them and their use as coating materials, adhesives, and sealing compounds or to prepare such compositions.
