İç mekan hijyen koşullarının arttırılmasında antibakteriyel duvar boyasının etkinliğinin değerlendirilmesi

Abstract

Imparting antimicrobial properties to indoor wall paint  Prevention of crosscontamination by antimicrobial paint  In-can preservative with long-term protection against bacteria and fungi Figure A. In vitro antibacterial effect of SilQUAT treated paint against E. coli and S. aureusPurpose: The aim of the study is to examine the antibacterial and in can-preservative effect of the SilQUATcontaining paint against different representative microorganisms in laboratory conditions. Figure A shows in vitro activity of SilQUAT treated paints. Theory and Methods:The antibacterial effect of the paint was tested against the S. aureus and E. coli bacteria, by modifying ISO 22196 standard test method. The in-can preservative effect of the treated paints against bacteria and fungi was evaluated by using modified International Biodeterioration Research Group's method. In each step, treated samples was compared with untreated paint samples, under the same standard conditions. Results:Tested paint samples showed a strong antibacterial effect with a decrease of > 99.99% (R> 2) against S. aureus and E. coli bacteria after 24 hours of contact time. Additionally, paint samples containing the tested compound as an in-can preservative showed a strong resistance against simulated microbiological attack, while there was no reduction in microorganism growth in the control samples. Conclusion:Antibacterial paints can be used to enhance the hygienic conditions of the interiors and to keep indoor surfaces as safe and clean as possible. Antibacterial paint additives, whose safety and efficacy were tested and proved scientifically, will also provide effective protection against biodeterioration. According to the results of the study, the tested compound can be used effectively as an interior wall paint to provide hygienic conditions. Additionally, the compound can be used as an in-can preservative to protect the paint products against microbial attack during the production process, storage and transport conditions.
