In the paint industry, there is a new biocide that is used to prevent the growth of microorganisms, such as bacteria in the paint. It has limited efficacy against fungi. Protecting their growth is essential to ensure the paint is not degraded or contaminated. This is particularly important for water-based or plastic emulsion paints, as they provide a favourable environment for microbial growth, which can lead to discoloration, bad odours, and deterioration of the paint film. New biocide is typically added to the paint formulation during the manufacturing process.
