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.

Methods and systems for coating metal substrates are provided. The methods and systems include a powder coating composition comprising a polymeric binder and an application package. The application package includes at least one antistatic component and at least one post-blended component. Use of the application package reduces back ionization and faraday cage effects during electrostatic application. The described methods provide coatings with optimal surface smoothness and edge coverage.

A method is designed to prepare foamed, opacifying elements each having a target light blocking value (LBV.sub.T) of at least 3, using a textile fabric substrate with a light blocking value (LBV.sub.S). The LBV.sub.T-S difference is calculated; a foamable aqueous composition is chosen; a dry coating weight for the foamable aqueous composition (when foamed) is determined to form a single dry opacifying layer that is foamed, dried, and densified to provide a dry thickness at least 20% less than the original dry thickness. The single dry opacifying layer a has light blocking value that is equal to LBV.sub.T-S, 15%. The desired foamable aqueous composition can be chosen from a set of similar compositions to achieve the desired LBV.sub.T with the noted textile fabric substrate using suitable mathematical formula relating dry coating weight to light blocking value and a suitable data processor.
