Method of preparing a pressurized container of pigmented paint
A pressurized package containing an initial paint formulation having a neutral or clear color is prepared by mixing a propellant and a clear non-pigmented base or a clear pigmented base or a white pigmented base in a pressurizable container. This pressurized container is then sold to retail stores where tints and/or pigment dispersions are injected into the pressurized container to arrive at a matched or selected final color and sold directly to the end user.
1. A method of preparing at a point of sale location a ready to use aerosol container of paint comprising, in combination,
a. providing a pressurized container for use in formulating a final paint mixture, the container having a filling opening and containing an initial paint formulation comprising a propellant and at least one of a clear non-pigmented base or a clear pigmented base or a white pigmented base;
b. introducing the pressurized container into a filling machine;
c. matching or selecting a final color and a gloss for the final paint mixture;
d. determining a recipe of tints or pigment dispersions or combination of both to achieve the matched or selected final color;
e. preparing a liquid formulation of tints, pigment dispersions or a combination of both based on the recipe determined in step d.;
f. adding the formulation from step e. directly to the pressurized container through the filling opening as a single injection; and
g. attaching a spray head into the filling opening.
2. The method of claim 1 further comprising removing a cap and a spray head from the container before introducing the container in the filling machine.
3. The method of claim 1 further comprising matching or selecting a final color using a spectrophotometer.
4. The method of claim 1 further comprising adding a flattening dispersion to the container to achieve the matched or selected gloss.
5. A method of preparing at a point of sale a ready to use aerosol container of paint comprising, in combination,
a. providing a pressurized container for use in formulating a final paint mixture having a filling opening and containing an initial paint formulation comprising a propellant and at least one of a clear non-pigmented base or a clear pigmented base or a white pigmented base;
b. introducing the pressurized container into a computer controlled filling machine in communication with a processor;
c. matching or selecting a final color and a gloss for the final paint mixture re;
d. executing a first computer algorithm in the processor to determine a recipe of tints or pigment dispersions or combination of both to achieve the matched or selected final color;
e. executing a second computer algorithm in the processor to automatically prepare a liquid formulation of tints, pigment dispersions or a combination of both based on the recipe determined in step d. and adding the formulation directly to the pressurized container through the filling opening as a single injection; and
f. attaching a spray head into the filling opening.
6. The method of claim 5 further comprising removing a cap and a spray head from the container before introducing the container in the filling machine.
7. The method of claim 5 further comprising matching or selecting a final color using a spectrophotometer.
8. The method of claim 7 further comprising using a spectrophotometer in communication with the processor.
