Abstract

The prodn. of aq. emulsion paints (I) based on binder resins with NCO reactive H atoms (II) and polyisocyanates (III) comprises mixing the components with water and forcing the mixt. through a nozzle with a small size in at least one dimension, under a pressure of 1-30 MPa. Also claimed are bimodal aq. emulsion paints based on OH gp. contg. resin binders (II) and (III), with a particle size distribution with one peak in the size range of 40-200 nm and a second peak in the range 200-2000 nm.
