Abstract
The present invention is directed to a method and apparatus for producing an aqueous paint from a plurality of premixed compositions at the point of sale wherein the apparatus is cleaned during the paint production. The premixed compositions include a pigment composition, a dispersant-thickening agent composition, a high resin content binder, and a low resin content binder. The dispersant-thickening agent, when supplied in a cleaning amount, effectively cleans the nozzles and valves, used to supply the premixed compositions to a receiving reservoir for the desired aqueous paint.
Claims9
A method for producing an aqueous paint composition comprising:
- selecting a paint composition recipe through a user interface, wherein the paint composition recipe comprises at least three different stable premixed aqueous compositions selected from the group consisting of a stable pigment composition, a stable dispersant-thickening agent composition, a stable high resin composition, and/or a stable low resin composition, wherein at least one of said three different stable premixed aqueous compositions is the dispersant-thickening agent;
- computationally determining a cleaning amount of the dispersant-thickening agent composition and subtracting the cleaning amount of the dispersant-thickening agent composition from a total amount of the dispersant-thickening agent composition to equal a dispensing amount of the dispersant-thickening composition;
- dispensing the dispensing amount of the dispersant-thickening agent composition and the at least three different stable premixed aqueous compositions to a receiving reservoir;
- and then dispensing the cleaning amount of the dispersant-thickening agent composition to the receiving reservoir and agitating the receiving reservoir to produce the aqueous paint composition.
