Abstract:
This invention relates to products of aqueous and other chemical synthetic routes for encapsulation of a core material with an inorganic shell and finished compositions of a core- shell particulate material for application in thermoplastic, thermoset, and coatings resins prior to compounding or application or subsequent thermal processing steps. Disclosed is a composition of particles containing a shell of inorganic oxides or mixed-metal inorganic oxides and a core material of complex inorganic colored pigment, laser direct structuring additives, laser marking, or other beneficial metal oxides, metal compounds, or mixed-metal oxide materials, wherein the shell material is comprised of any single oxide or combination of oxides is taught. Preferred elements of composition for the shell are oxides and silicates of B, Ni, Zn, Al, Zr, Si, Sn, Bi, W, Mo, Cr, Mg, Mn, Ce, Ti, and Ba (or mixtures thereof). Applications may include, but are not limited to, coatings or plastic articles or materials for molded interconnect devices, durable goods, housings, assemblies, devices, and articles that are to be exposed to additional thermal processing. The resulting core-shell materials function in plastic and coatings formulations by minimizing or eliminating detrimental interactions with the resins and metal containing additives resulting in loss of mechanical properties.
Abstract:
A composite material comprising an amorphous, porous material with nanocrystalline material in its pores has been found to be a UV absorber. The porous material is a matrix of pores that act as a scaffold for the nanocrystalline material. The particles of the nanocrystalline material are isolated, which mean that they do not connect to each other. In some embodiments, the nanocrystalline material is completely inside the pores of the porous material. In some embodiments, the nanocrystalline material may stick out of some or all of the pores of the porous material. In some embodiments, the nanocrystalline material is a cerium oxide material. In some embodiments, the nanocrystallite ranges in size from 2 to about 100 nm on its longest axis, with an aspect ratio from about 1 to about 1.5.

Abstract:
A mixture of zirconium hydroxides or zirconium basic carbonate with vanadium oxide (V205) co-reacts in high temperature aqueous slurry to form respectively an amorphous material, believed to be based on a zirconium analog of a zeolite structure, and a solid solution of zirconium oxide with vanadium oxide. The subject compositions, free of hexavalent chromium, are highly effective in providing blister- free corrosion prevention in typical coil and aerospace grade epoxy primer and color coat combinations.
Abstract:
A black pigment substantially free of objectionable transition metal materials is disclosed. This pigment is particularly useful for coloring glass since the absence of the transition metals gives it excellent recycling properties. The pigment is an alkaline earth (preferably strontium) iron manganese oxide material as specifically defined the in the present application.
