Antimicrobial paints were formulated based on various nano particles of zinc oxide
and organic biocide. The aqueous acrylic dispersion was used as a binder for this
system. A control paint without nanoparticles was formulated. The antimicrobial
ability, shelf-life stability and photoactivity were assumed in these paints based on
nano zinc oxide with organic biocide. It is possible to observe the photoactivity
thanks to a change in organic dyes due to oxidative-reductive reaction. The agar
dilution method was used for a test of the antimicrobial ability. The Escherichia
coli, Pseudomonas aeruginosa and Staphylococcus aureus were chosen as test
bacteria. A great antibacterial inhibition of Escherichia coli and Staphylococcus
aureus sis exhibited both coatings, and they are antimicrobially active after 12
months of shelf stability.
