United States. Manufacturer Sherwin Williams announced the introduction of a new paint called Paint Shield, which is the first EPA-registered microbicidal paint that continuously removes these hard-to-treat infection-causing bacteria after two hours of exposure to painted surfaces.
By killing these infectious bacteria on painted surfaces, Paint Shield offers customers an important new tool to help prevent the spread of bacteria that can cause nosocomial infections (HAIs). Surfaces painted with this kind of paint remove more than 99.9% of staphylococcus (Staphylococcus aureus), MRSA (methicillin-resistant Staphylococcus aureus), E. coli (Escherichia coli), VRE (Vancomycin-resistant Enterococcus faecalis), and Enterobacter aerogenes after two hours of exposure.
EPA's test protocol showed that once applied, the effectiveness of paint shielding lasts up to four years, as long as surface integrity is maintained.
Paint Shield can be applied on hard interiors, non-porous ceilings, walls, doors and moldings. It is ideal for a variety of settings such as health centers, sports facilities, schools, day centers, elder care communities, residential housing, hospital configurations, and cruise ships.
The product will initially begin to be marketed in the United States during the beginning of this year.
