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 Tof 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.

Aqueous coating material that is cured thermally and/or by actinic radiation, and its use

A mixer system, for preparing two-component water-dilutable coating agents, includes a plurality of substantially water-free base colors and a pigment-free aqueous component. One or more of the base colors can be mixed together with a suitable amount of the aqueous component to match a preexisting coating color on a substrate to be repaired. Each of the base colors includes a pigment, an organic solvent and a first binder. The pigment-free aqueous component includes water and a second binder. The second binder is a polymer made from a mixture which includes a monomer component, an initiator, and an aqueous dispersion of a polyurethane resin. Cured coatings which are prepared from compositions using the disclosed mixer system exhibit improved condensation resistance, as compared with previously known coatings.
