  • 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.

  • Publication number: 20160237302
    Abstract: The present invention provides for compositions comprising at least one polyketone; and at least one acyl hydrazide; wherein, the polyketone comprises at least two levulinic acid moieties. The present inventions also provide for novel polyhydrazone compounds. Examples of completely water-soluble compositions comprising acyl hydrazide and polyketone that form polyhydrazones compounds are provided herein. The compositions and polyhydrazones of the present invention are useful in the preparation of coating materials and the formation of films.

  • 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.
