摘要： To produce a twin-component paint and especially a polyurethane paint emulsion, the two paint components of a bonding agent dispersion (1) with isocyanate reactive hydrogen atoms and polyisocyanate (2) are fed by pumps (3, 4) to a mixer (5) to give a twin-component mixture. - To produce a twin-component paint and especially a polyurethane paint emulsion, the two paint components of a bonding agent dispersion (1) with isocyanate reactive hydrogen atoms and polyisocyanate (2) are fed by pumps (3, 4) to a mixer (5) to give a twin-component mixture. The mixture is passed to a homogenizer (7), where at least a part is recirculated (8) through it a number of times. The components are fed separately to the mixer at a maximum pressure of 2.5 MPa.
