Abstract: A biocidal material includes a carrier, a plurality of copper-containing glass particles, and at least one co-biocide selected from isothiazolinones, bicyclic oxazolidines, and bromine nitrogen-based compounds. A minimum bactericidal concentration (MBC) of a combination of the at least one co-biocide and the plurality of copper-containing glass particles is less than an MBC of the at least one co-biocide in the absence of the plurality of copper-containing glass particles.

Abstract: A biocidal material and method of forming is provided. The biocidal material includes a carrier and a plurality of treated copper-containing particles including a particle surface pre-treatment. The surface pre-treatment includes a copper-chelating material.

Abstract: According to various examples of the present disclosure, a biocidal dispersion includes one or more inorganic glass comprising copper particles. The biocidal dispersion further includes a dispersant, a thickener, or a mixture thereof. The inorganic glass comprising copper is homogenously distributed about the biocidal dispersion and is in a range of from about 3 wt % to about 88 wt % of the biocidal dispersion.

Abstract: A composition for forming a biocidal coating is provided. The composition has a log reduction of at least 2 and a CIEL*a*b* delta E*value less than about 30.

Abstract: A composition including a core-shell polymeric particle, the core including, when dry, at least one void and the shell including, as polymerized units, from 18% to 50%, by weight based on the weight of the shell, monomer selected from the group consisting of acrylonitrile, methacrylonitrile, acrylamide, methacrylamide, and mixtures thereof is provided. Also provided is a composition including an organic medium and a core-shell polymeric particle, the core including, when dry, at least one void and the shell having a calculated shell-organic medium interaction parameter, XPS>1.15 and a method for providing opacity to a dry composition.

Abstract: The present invention relates to a latex composition comprising a) an opaque polymer having a pigment volume concentration of from 18 to 28; b) fully or partially polymer encapsulated TiO2 particles having a pigment volume concentration of from 8 to 18; c) an extender having a pigment volume concentration of from 0 to 10; d) a binder; e) a thickener; and f) water. Notwithstanding the surprisingly high pigment volume concentration of opaque polymer, the composition—upon application to a substrate—gives a coating with a gloss or semi-gloss finish, excellent hiding, and acceptable burnish resistance.

Abstract: This invention is an aqueous paint composition comprising an alkyd emulsion; a dispersion of organic extender particles, which particles comprise, when dry, one or more void; and one or more pigment. The aqueous paint composition provides high gloss decorative and protective coatings for various substrates, which coatings are extended with lower cost-in-use opaque polymer while still providing the high gloss performance of unextended alkyd emulsion paints. Also provided is a method for providing the high gloss coating.

Abstract: An aqueous polymer composition including a plurality of comb copolymer particles is disclosed. The comb copolymer particles contain comb copolymer having a polymer backbone with at least one attached graft segment. The polymer backbone and the at least one graft segment have select compositional ranges and select glass transition temperature ranges. Further, the comb copolymer contains as a polymerized unit at least one select monomer such as, aldehyde reactive group-containing monomer or certain styrenic monomers.
