  • Publication number: 20230159782
    Abstract: The present invention relates to a composition comprising an aqueous dispersion of cerium (III) carbonate particles having a z-average particle size in the range of from 5 nm to 500 nm, which composition further comprises a capping ligand. The composition is useful as an additive in formulations that contain polymer, pigments, dyes, or tints, or a combination thereof, to promote color retention and attenuate unwanted color formation in coatings formed from these formulations.
    Type: Application

  • Publication number: 20230144769
    Abstract: The present invention relates to a method of preparing an aqueous dispersion of nanosized cerium (III) carbonate particles comprising the step of admixing in water a) a water-soluble ammonium cerium (III) salt, b) a water-soluble carbonate, and c) a capping ligand to form an aqueous dispersion of cerium (III) carbonate particles having a resultant z-average particle size is in the range of from 5 nm to 500 nm. The method is useful for the preparation of an additive that is useful in formulations that contain polymer, pigments, dyes, or tints, or a combination thereof, to promote color retention and attenuate unwanted color formation in coatings formed from these formulations.

  • Publication number: 20220363908
    Abstract: The present invention is a composition comprising an aqueous dispersion of metal oxide pigment particles coated with an organosilane polymer comprising structural units of an alkyltrihydroxysilane or a salt thereof, a dialkyldihydroxysilane or a salt thereof, and an ancillary alkylsilane triol. The composition of the present invention provides hydrophobicity to pigment particles, thereby imparting water resistance, and allows for high loadings of pigment in water without increased viscosity. The dispersion is further useful for providing stain and corrosion resistance in coatings arising from paints.
