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. |

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
