Biocidal coatings are specialized surface treatments designed to prevent the growth of harmful microorganisms, such as bacteria, fungi, and viruses. These coatings contain active substances that can kill or inhibit the reproduction of these pathogens, making them useful in various applications, including healthcare settings, food processing, and public spaces. These coatings can be applied to a variety of surfaces, including metals, plastics, and textiles. By providing a protective barrier, biocidal coatings help reduce the risk of infections and contamination, contributing to improved hygiene and safety in environments where cleanliness is critical, such as hospitals and laboratories.
