Abstract

See full text

Described herein is a mixer system for producing aqueous coating materials from at least one aqueous pigment paste A, including at least one color pigment, and at least one pigment-free component B, including an aqueous, acrylate-based microgel dispersion having a glass transition temperature Tg of 50 to 60° C., where both the aqueous pigment paste A and the component B each have a VOC value of less than or equal to 250 g/L. Further described herein is a method for producing aqueous coating materials having a VOC content of 0 to 250 g/L, in which the individual components A and B are stored separately and not mixed until shortly before application, to give the aqueous coating material. Further described herein is a method of using the mixer system for producing aqueous coating materials for refinishing and/or for coating automobile bodies and/or plastics parts.
