| Résumé : |
An acrylic binder has been developed with cationic functions that disrupt the cell membranes of microbes. This protects coatings and substrates without any adtive releasing of biocides and without promoting the development of resistance. Test paints showed excellent resistance to microbial attack, with performance maintained after washing tests. |
| Note de contenu : |
- problems associated with conventional biocides
- Regulatory product classification summarised
- Limitations and restriction on currently used biocides expected
- Nature inspires new approach to antimicrobial coatings
- How the biocidal binder functions
- Preparation and testing of antimicrobial wall paints
- High protection and resistance to washing
- Legislative and environmental advantages
- FIGURES : 1. Active release working mechanism of biocides over time - 2. "MyCroFence" novel active antimicrobial surface coating concept - 3. Wet scrub resistance test results - 4. Pictures showing biocidal efficacy test against aspergillus niger - 5. The inner lining of the left glass jar with tomato still fresh was treated with a transparent coating that contained the biocidal binder ; the jar on the right was treated with a market reference product
- TABLES : 1. Antimicrobial wall paint based on new antimicrobial binder - 2. Selected commercially available resins ustable as co-binders - 3. Antimicrobial performance of paints before and after washing test. A log reduction of > 2 indicates the coating has antimicrobial efficacy and > 3 indicates a strong antimicrobial efficacy |
