  • Architectural paint and stain tinting system with tip drying resistance
    Patent number: 8822580
    Abstract: Custom-tinted paints and stains are made using an array of low VOC concentrated liquid colorants including at least at least white colorant; black colorant; and green-hued, blue-hued and red-hued primary colorants at least one of which primary colorants comprises polyalkylene glycol humectant, ethoxylated surfactant and extender pigment. For colorants in the array containing polyalkylene glycol humectant, the humectant and ethoxylated surfactant amounts are sufficiently high and extender pigment amount is sufficiently low so that the colorants will not problematically plug colorant dispenser orifices if left in the dispenser without an orifice cap for a full day. The polyalkylene glycol humectant is also present in an amount sufficiently low so that dried paint films made by mixing the colorants with a clear waterborne base paint will resist blocking.
