Abstract: Described herein is a specific aqueous two-component coating composition including an epoxy resin-based paint base component (1), and a polyamine-based curing component (2), where the paint base component (1) includes at least one aqueous dispersion of at least one pigment (P) and/or filler (F) in at least one epoxy resin (E), where the at least one epoxy resin (E) has (i) a maximum sedimentation rate of not more than 17,500 micrometers per hour and a glass transition temperature of less than 0° C., or (ii) a maximum sedimentation rate of at least 12,500 micrometers per hour and a glass transition temperature of at least 0° C.

Abstract: Described herein is an aqueous resin dispersion (AD) including a resin component (R) including at least one di- and/or polyfunctional monomeric primary and/or secondary amine (M) and polyfunctional polymeric organic amines having primary and/or secondary amino groups. Also described herein is an aqueous two-component coating composition including the resin dispersion.

Abstract: Provided are devices for delivering, metering and mixing liquid paint components, comprising (a) a paint supplying device, which comprises two or more paint reservoirs or comprises one paint reservoir, having two or more chambers for different paint components, (b) a metering device, which is arranged downstream of the paint supplying device and comprises rotating delivery devices serving as metering units, the delivery devices each having a pair of wheels and being connected to one another by a common spindle in such a way that their rotational speeds are in fixed ratios in relation to one another, and (c) a static mixing device, which is arranged downstream of the metering device and the outlet of which may be connected to a paint spray gun. Also provided are methods for using the device and for coating a substrate using the device in combination with a paint spray gun.
