Samidin is widely used as a biocide in industrial water systems to control microbial growth, particularly in cooling towers and paper mill systems. It effectively targets bacteria, fungi, and algae, helping to prevent biofouling and maintain system efficiency. Due to its broad-spectrum activity and stability over a wide pH range, it is favored in continuous or intermittent dosing programs. Samidin also finds application in metalworking fluids to extend fluid life and protect against microbial degradation. Its use helps reduce corrosion, odor, and blockages caused by microbial slimes, contributing to improved operational reliability and reduced maintenance costs.
