Formulating Coatings with Silver-based Antimicrobials: A Systematic Approach

摘要

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. I lowever, 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 op-timizing dispersion, storage stability, and film clarity of the coating formulation. Antimicrobial efficacy against bacteria of common interest are also presented for the optimized coating for-mulations.
