The invention relates to pigmented powder paint dispersions (pigmented powder slurries) which can be produced by (1) mixing at least two liquid components, each of which contains at last one liquid starting product, in a static mixer, whereby a liquid is obtained; (2) emulsifying the resulting liquid (1) in an aqueous medium in a dispersing unit, whereby an aqueous emulsion of liquid particles is obtained and (3) allowing the emulsion (2) to cool off so that a suspension of dimensionally stable particles is formed, whereby the aqueous medium represents the suspension of at least one pigment. The invention also relates to a method for the production of said suspensions and to their use as coatings, adhesives and sealants or to the production thereof.
L'invention concerne des suspensions de peinture en poudre pigmentées (mélanges de poudre pigmentés), pouvant être obtenues par (1) mélange d'au moins deux composants liquides, contenant chacun au moins un produit de départ liquide, dans un mélangeur statique de façon à obtenir un liquide, (2) émulsion du liquide (1) dans un agrégat dispersant dans un milieu aqueux de façon à obtenir une émulsion aqueuse de particules liquides et (3) refroidissement de l'émulsion (2) de façon à obtenir une suspension de particules présentant une stabilité dimensionnelle, le milieu aqueux représentant une suspension d'au moins un pigment. L'invention concerne en outre un procédé de production de ces suspensions, ainsi que leur utilisation comme enduits, adhésifs et mélanges d'étanchéité ou pour produire ceux-ci.
