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.
Claims18
An antimicrobial paint composition for forming an antimicrobial coating, said antimicrobial paint composition comprising:
- a carrier vehicle;
- a film-forming polymer;
- a glass comprising copper;
- a non-copper pyrithione salt;
- and
- titanium dioxide (TiO2) as a colorant;
- wherein said copper and said pyrithione salt interact to form copper pyrithione in the antimicrobial paint composition and/or the antimicrobial coating formed thereby;
- wherein the glass comprising copper is present in an amount of from about 0.08 to about 2.0 weight percent based on the total weight of the antimicrobial paint composition;
- wherein the titanium dioxide (TiO2) is present in an amount of from 11 to 30 weight percent based on the total weight of the antimicrobial paint composition;
- and
- wherein the glass comprising copper and the non-copper pyrithione are present in a weight-to-weight ratio of from greater than about 12:1 to about 20:1.
