Antimicrobial slurries are advanced liquid formulations that incorporate metal ion–based antimicrobial agents into stable dispersion systems. By utilizing innovative wet milling or nanodispersion technologies, these products ensure uniform particle size distribution, excellent stability, and high compatibility with polymer-based applications. Unlike conventional organic biocides, antimicrobial slurries are solvent-free, environmentally friendly, and do not generate microbial resistance, making them a safer and more sustainable choice.When applied to coatings, inks, or textiles, our antimicrobial slurries provide broad-spectrum and long-lasting protection against bacteria, fungi, and viruses.
As a professional supplier of polymer additives, Alfa Chemistry offers a portfolio of high-quality antimicrobial slurries — including zinc, copper, and silver-based systems — to help industries enhance hygiene, durability, and product value.
