Problems solved by technology

Additionally, common commercial biocides impart color to paints when used in effective concentrations, which greatly limits the palette available to formulators and greatly limits consumer aesthetics
Similarly, common metal-based solid film biocides can cause paint discoloration when exposed to light

Abstract

An antimicrobial paint composition for forming an antimicrobial coating is disclosed. The antimicrobial paint composition comprises a carrier vehicle, a film-forming polymer, a glass comprising copper, and a non-copper pyrithione salt. A method of preparing the antimicrobial coating on an indoor surface with the antimicrobial paint composition is further disclosed. The method comprises applying the antimicrobial paint composition on the indoor surface and forming the antimicrobial coating on the indoor surface from the antimicrobial paint composition.

Description

technical field [0001] The present invention relates generally to a coating composition, and more particularly, to an antimicrobial coating composition, a method of making the antimicrobial coating composition, and a method of making an antimicrobial coating therefrom. Background technique [0002] Coating compositions, such as latex paint compositions, typically exist as liquid emulsions in which polymer droplets are mixed into a carrier vehicle along with pigments and other excipients. Such coating compositions are typically placed on surfaces to form solid film coatings, eg, paints, for aesthetic and functional purposes such as decoration, surface protection, insulation, passivation, and the like. [0003] Conventional coating compositions typically contain four categories of components: carrier vehicle, binders, pigments and additives. [0004] Carrier The vehicle is the fluid component of the coating composition which serves to carry, dissolve or solubilize all other c...
