Paint tinting adjuvant with siccative for liquid colorant system
A point-of-sale custom color system for tinting base paints and stains includes an array of water-only fluid colorants, including at least white, green, blue and red water-only colorants, which can be used to tint water-borne paints and stains. When tinting solvent-borne base paints or stains, at least one siccative is added to the solvent-borne base paint or stains at the point-of sale and a synergist containing one or more surfactants and optional dispersing agents or optional cosolvents is also added to or is a part of the solvent-borne base paint or stains. Collectively, the siccative and synergist enable effective tinting using the water-only colorants and suitable drying characteristics of the solvent-borne paint or stain.

2 . The point-of-sale custom color system according to claim 1 , further comprising at least one water-borne base paint or stain and at least one solvent-borne base paint or stain, the base paints or stains being packaged in largely but incompletely filled point-of-sale containers with a volume of about 0.2 to 20 L equipped with an openable and recloseable lid, cap or other closure for an opening through which colorant may be dispensed from the automated or manual colorant dispenser into the base paint or stain.
3 . The point-of-sale custom color system according to claim 2 , wherein the solvent-borne base paint or stain does not already include sufficient ingredients from the synergist to disperse the water-only fluid colorants into such solvent-borne base paint or stain without causing objectionable rub-up according to the specification.
4 . The point-of-sale custom color system according to claim 2 , wherein the solvent-borne base paint or stain is siccative-free.
5 . The point-of-sale custom color system according to claim 1 , wherein the at least one siccative and at least one synergist are pre-mixed together and disposed in at least one dispenser slot normally reserved for a colorant in an automated colorant dispenser, and dispensed into the solvent-borne base paint or stain using an automated colorant dispenser metering circuit.
6 . The point-of-sale custom color system according to claim 1 , wherein the at least one siccative comprises a primary metal drier, a through metal drier, an auxiliary metal drier, or a combination thereof.
7 . The point-of-sale custom color system according to claim 6 , wherein the at least one siccative comprises a primary metal drier, wherein the metal is selected from the list consisting of cobalt, manganese, iron, and vanadium.
8 . The point-of-sale custom color system according to claim 6 , wherein the at least one siccative comprises a through metal drier, wherein the metal is selected from the list consisting of aluminum, cerium, lithium, neodymium, potassium, strontium, and zirconium.
9 . The point-of-sale custom color system according to claim 6 , wherein the at least one siccative comprises an auxiliary metal drier, wherein the metal is selected from the list consisting of calcium, barium, and zinc.
10 . The system according to claim 1 , wherein the mixture comprises about 1 wt. % to 20 wt. % of the at least one siccative.
11 . The point-of-sale custom color system according to claim 1 , wherein the contained is a metal or plastic box, can, cartridge, jar, pouch, squeeze bottle, syringe or collapsible tube.
12 . The point-of-sale custom color system according to claim 1 , wherein the synergist comprises a dispersing agent and an optional cosolvent.
13 . The point-of-sale custom color system according to claim 1 , wherein all of the colorants in the array are water-only fluid colorants.
14 . The point-of-sale custom color system according to claim 1 , wherein the solvent-borne base paint or stain comprises an alkyd paint, polyurethane paint, epoxy paint or oil-based stain.
15 . The point-of-sale custom color system according to claim 1 , wherein the system comprises a first mixture comprising a first synergist and a first siccative configured to be added for the creation of light colored paints or stains, and a second mixture different than the first mixture, the second mixture comprising a second synergist and a second siccative and configured to be added for the creation of dark colored paints or stains, wherein the first and second mixtures are independently dispensable into a solvent-borne base paint or stain.
16 . A method for point-of-sale custom paint or stain tinting, the method comprising using an automated or manual colorant system to dispense into water-borne and solvent-borne base paints or stains at a retail, wholesale or combined retail/wholesale outlet, one or more water-only fluid colorants at least one siccative and at least one synergist the system comprising:
a) an array of the water-only fluid colorants including at least white, green, blue and red colorants comprising one or more pigments or dyes and a surface treatment, the colorants being packaged in containers with a volume of about 0.5 to about 5 L and from which colorant is gravimetrically or volumetrically dispensed via an automated or manual colorant dispenser into a base paint or stain with a volume of about 0.2 to 20 L; the at least one siccative; and
