| Résumé : |
Adding a permanent microbiocide to a coating material can have two different intentions: an active kill effect to microbes coming into contact with the coating, and the preservation against paint disfiguring or deteriorating organisms. In the second case the microbicide does nothing but protect the coating against colonization, while in the first case the coating has to have active biocidal properties. These two intended biocide uses are treated differently by regulatory bodies, and require different test methods to demonstrate efficacy. The antimicrobials for paints must meet the regulatory standards in the individual markets and must demonstrate experimentally a benefit to the end user. Paint films in interior environments are subject of colonization by fungi and yeasts, while bacteria in general do not find the conditions hospitable for growth. Film preserving biocides for interior coatings must therefore be effective with a broad based activity towards fungi and should meet the other requirements for environmentally acceptable paints (especially zero VOC). The antimicrobial activity must come together with favorable physical properties to improve the resistance of the coating. For a modern zero-VOC paint film preservative based on IPBC and BCM, efficacy and active substance mobility data support the favorable realworld experience. CT. |
