A composite pigment containing a substrate particle and a pigment layer arranged on a surface of the substrate particle, wherein the pigment layer contains a pigment, a resin and a metal oxide, and the metal oxide contains at least one selected from the group consisting of a silicon oxide, a polysiloxane, and composites thereof.

The present invention relates to organopolysiloxane compositions comprising an organopolysiloxane having, per molecule, at least two alkenyl groups, an organopolysiloxane having, per molecule, at least two SiH units, a hydrosilylation catalyst, and a thermally conductive filler, the thermally conductive filler comprising at least 40% by weigh of metallic silicon, and a specific particle size distribution. The invention further relates to a silicone elastomer which can be obtained by cross-linking and/or curing the composition, as well as its use as a thermally conductive material for coating or filling, in particular for the automotive field, in particular for the field of electric vehicles.

Aqueous coating compositions providing enhanced anticorrosive and water-resistant properties. The anticorrosive coating comprises water borne resin, surface-hydrophobic inorganic pigments, and/or surface-hydrophobic inorganic extenders.

A catalyst-free synthesis method for the formation of a metalorganic compound comprising a desired (first) metal may include, for example, selecting another (second) metal and an organic solvent, with the second metal being selected to (i) be more reactive with respect to the organic solvent than the first metal and (ii) form, upon exposure of the second metal to the organic solvent, a reaction by-product that is more soluble in the organic solvent than the metalorganic compound. An alloy comprising the first metal and the second metal may be first produced (e.g., formed or otherwise obtained) and then treated with the organic solvent in a liquid phase or a vapor phase to form a mixture comprising (i) the reaction by-product comprising the second metal and (ii) the metalorganic compound comprising the first metal. The metalorganic compound may then be separated from the mixture in the form of a solid.

Processes for making surface-modified layered double hydroxides (LDHs) are disclosed, as well as surface-modified LDHs, and their uses in composite materials. The surface-modified LDHs of the invention are more hydrophobic than their unmodified analogues, which allows the surface-modified LDHs to be incorporated in a wide variety of materials, wherein the interesting functionality of LDHs may be exploited.

A blended composition containing uncoated Al.sub.2O.sub.3 flakes having a thickness of ≥500 nm and a D.sub.50-value of 15-30 μm and a D.sub.90-value of 30-45 μm, and/or coated Al.sub.2O.sub.3 flakes having a thickness of ≥500 nm and a D.sub.50-value of 15-30 μm and a D.sub.90-value of 30-45 μm, which have been coated with at least one layer of a metal oxide, mixtures of at least two metal oxides, metal, metal sulphide, titanium suboxide, titanium oxynitride, FeO(OH), metal alloys and/or rare earth compounds, and their use in various formulations.

A black IR reflective or transmissive pigment from which LiDAR responsive black coatings can be formed where the pigment displays a Blackness M.sub.y value similar to non-IR reflective carbon black. The CuO particles display small crystallites of less than 18 nm and an (−111)/(111) reflectance intensity ratio of less than 1.2. A method of forming the CuO particles includes precipitation of CuCO3 or CuCO.sub.3/Cu(OH).sub.2 using an alkali carbonate as a precipitant and calcining the precipitate at about 300° C. to about 400° C.

Porous metal oxide microspheres are prepared via a process comprising forming a liquid dispersion of polymer nanoparticles and a metal oxide; forming liquid droplets of the dispersion; drying the droplets to provide polymer template microspheres comprising polymer nanospheres; and removing the polymer nanospheres from the template microspheres to provide the porous metal oxide microspheres. The porous microspheres exhibit saturated colors and are suitable as colorants for a variety of end-uses.

Modified copper chromite spinel pigments exhibit lower coefficients of thermal expansion than unmodified structures. Three methods exist to modify the pigments: (1) the incorporation of secondary modifiers into the pigment core composition, (2) control of the pigment firing profile, including both the temperature and the soak time, and (3) control of the pigment core composition.

A process is described for manufacturing white pigment containing products. The white pigment containing products are obtained from at least one white pigment and impurities containing material via froth flotation.
