Widely used as a biocide in water-based industrial systems, this chemical effectively controls the growth of bacteria, fungi, and algae. It is commonly added to paints, adhesives, and latex emulsions to prevent microbial spoilage during storage and use. Frequently found in metalworking fluids, it helps maintain fluid integrity by inhibiting bacterial degradation that can cause odor and performance loss. Also used in cooling tower water treatment to control microbial contamination and biofilm formation. Its broad-spectrum activity and water solubility make it suitable for continuous or intermittent dosing in industrial preservation.
