DDMS is primarily used as a biocide in various industrial applications. It is effective in controlling microbial growth in water systems, such as cooling towers and industrial water treatment processes. Its antimicrobial properties help prevent the formation of biofilms, which can lead to equipment corrosion and reduced efficiency. Additionally, DDMS is utilized in the preservation of materials like paints, coatings, and adhesives, where it inhibits the growth of bacteria and fungi, extending the shelf life and maintaining the quality of these products. Its application is also seen in the oil and gas industry, where it is used to protect pipelines and storage tanks from microbial contamination.
