Abstract

Provided herein is a mixer system for producing refinish compositions, more particularly for the sector of automotive finishing, including at least mutually different components (1), (2), and (3), namely component (1) as base varnish, component (2) as tinting base, and component (3) as rheology module, with at least one of components (1) to (3) including at least one aqueous dispersion including at least one polymer prepared by multistage emulsion polymerization, and at least one of components (1) to (3) including at least one aliphatic monoalcohol having 5 carbon atoms and/or at least one aliphatic monoalcohol having 6 carbon atoms. Further provided herein is an aqueous refinish composition that is produced by the mixing of components (1) to (3), and a method for producing aqueous refinish compositions. Further provided herein is a use of the mixer system for producing aqueous refinish compositions for automotive refinishing.
