  • Patent number: 10544323
    Abstract: A dry pigment paint system includes dry pigment doses that may be used alone or combined with other dry pigment doses to provide a desired color when dispersed in a paint base. The system may use a plurality of dry pigment formulations, with each dry pigment formulation consisting of one or more dry pigments, generally a plurality of dry pigments. Each dry pigment dose may include a single dry pigment formulation. Each does may be a tablet, capsule or sachet. Various dose forms and dispensing systems are disclosed. Formulations of easily dispersible (ED) pigments comprising a combination of a carboxylic acid polymer and a non-ionic alkoxylated surfactant are also disclosed. The combination is used in the formulation of a plurality of pigments. The formulations are suitable for mixing with a base medium at the point-of-sale (PoS) or by the end user.

  • Publication number: 20170183260
    Abstract: A method of colouring cementitious building materials such as concrete is disclosed. The method uses flowable, spray-dried, particulate formulations of inorganic pigments prepared using a selection of formulants that do not substantially effect primary ettringite formation. Quantities of the formulations may conveniently be dispensed into a slurry of cement and water by gravimetric or volumetric means.

  • Patent number: 9382158
    Abstract: Method of preparing a colored self-levelling cementitious floor covering by mixing a colorant with a cementitious floor covering premix used in forming of the colored self-levelling cementitious floor covering. The colorant is a flowable, spray-dried, particulate formulation prepared from a mixture of ingredients in water containing 85 to 95% by weight of one or more inorganic pigments, 3 to 7% by weight of poly(ethylene glycol) having a median molecular weight in the range 7,000 to 9,000, 3 to 6% by weight carboxylated acrylic co-polymer dispersant and 0.5 to 2.0% by weight hydroxylated amine.
