| Résumé : |
Silver-based antimicrobials have increased in popularity due to their high efficacy against bacteria and low ecotoxicity. There is growing interest in using them for antimicrobial coatings. However, formulation of these products into traditional coating systems can present some unique challenges, including film discoloration, loss of gloss, poor rheology, and shelf stability. This article presents a systematic study of the incorporation of silver-based antimicrobials into starting point formulations of different industrial and decorative coatings, with a focus on optimizing dispersion, storage stability, and film clarity of the coating formulation. Antimicrobial efficacy against bacteria of common interest are also presented for the optimized coating formulations. |
