  • Pigmented powder paint suspensions (pigmented powder slurries), production method and utilization thereof
    Patent number: 7629407
    Abstract: Pigmented powder coating suspensions (pigmented powder slurries) 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 liquid, (2) emulsifying the liquid (1) in an aqueous medium in a dispersing unit, to give an aqueous emulsion of liquid particles, and (3) cooling the emulsion (2) so that a suspension of dimensionally stable particles is formed, wherein said aqueous medium comprises the suspension of at least one pigment; and also processes for preparing them and their use as coating materials, adhesives, and sealing compounds or to prepare such compositions.
    Type: Grant

  • Powder paints, method for production and use thereof
    Patent number: 7449516
    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.
