  • Patent number: 5530039
    Abstract: Process for manufacturing stopping compounds, in particular such as can be used for motor vehicle repair lacquering, in which in a first stage at least 90 wt.-% of the solvents required and 80 to 100 wt.-% of the binding agents required are dispersed together with such a proportion of the pigments and/or extenders as is required in order to ensure that the mixture can be dispersed in a high-speed agitator mill, as well as optionally together with the required additives in a high-speed agitator mill, in particular a bead mill or sand mill, whereupon the dispersed material produced is, in a second stage, mixed with the remaining amounts of pigment and/or extender as well as optionally the remaining amounts of binding agent and solvent and dispersed in a dissolver to the required fineness.
