Abstract: An antimicrobial composition comprising an inorganic particle with a first coating providing antimicrobial properties and a second coating providing a protective function is disclosed with a method for preparing the same and uses; further processes for producing polymeric articles and a method for controlling microorganisms are also disclosed.

Abstract: A product and process are disclosed that relate to electroconductive powders based on tantalum, niobium, or phosphorus or any combination thereof doped tin oxide and coatings containing such powders. These powders can be used for making transparent coated films that are conductive and have desirable properties for a number of end uses. Some important end uses are in static dissipative fiber and films, coatings for recyclable containers, materials involved in packaging, where the presence of certain heavy metals is undesirable, transparent conductive coatings, among other uses.

Abstract: Synthetic organic fibers containing finely divided, inorganic particles that have certain organic polymeric coatings have improved dispersibility within a matrix material and significantly less abrasiveness than do identical fibers containing such particles without any such polymeric coatings.

Abstract: The disclosure relates broadly to a new class or type of electroconductive powders (ECP), designated as Polytype ECP (PECP), comprising intimate mixtures of several types of ECP powders. PECP mixtures possess a lower electrical resistivity, or a higher electroconductivity, than would be expected from the weighted average of the component ECP powders. PECP are multi-component and may contain many different types of ECP. ECP components of the PECP can be selected from at least one member of the group consisting of crystallites of tin oxide containing antimony in solid solution, crystallites of antimony-containing tin oxide with uniformly distributed amorphous silica, two dimensional networks of crystallites of antimony-containing tin oxide in a unique association with amorphous silica or silica-containing material, filler materials, metal coated powders, conventional ECP materials such as carbon, aluminum powder, among others.
