Color and / or effect powder slurries, process for their preparation and mixing system for color and / or effect powder slurries

Colour- and/or effect-producing powder slurries may be produced, whereby (A) a powder slurry clear lacquer is mixed with (B) at least one colour- and/or effect-producing slurry, or alternatively, (A) a colour- and/or effect-producing powder slurry is mixed with at least one colour- and/or effect-producing slurry, comprising a different colour tone and/or optical effect to powder slurry (A). The invention further relates to a method for the production of the colour- and/or effect-producing powder slurries and a mixing system and modular system based on the colour- and/or effect-producing powder slurries (A) and (B) and, optionally, the powder slurry clear lacquer (A).
