Application

2,2-Dibromo-3-Nitrilopropionamide (DBNPA) is a quick-kill, non-oxidizing biocide that easily hydrolyzes under both acidic and alkaline conditions. It is preferred for its instability in water as it quickly kills and then quickly degrades to ammonia and bromine ions. DBNPA acts similar to the typical halogen biocides. 2,2-Dibromo-3-Nitrilopropionamide (DBNPA) is used in paper industry and as preservatives for coatings and slurries and to control microbial fouling in paper mills and process water systems. DBNPA is also used as slime control on papermachines.
