Biocides in broad spectrum. DBNPA is widely used in industrial circulating water system, large air-condition and the large center of sewage treatment to eliminate microorganism and alga and shuck off clay. 2 2-dibromo-3-nitrilo-propionamide is also used in the process of paper making to prevent reducing quality of paper by generation of microorganism. It is suitable for metal cutting of cooling liquor, recovery system of oil, latex and ply-woods as anti-spy biocides. It has following advantages: easy to handle; no unusual oxidation hazards; similar performance and safety in paper and oilfield applications; used for slime control in the wet-end of the paper mill and performs exceptionally well against slime-forming bacteria. 2 2-dibromo-3-nitrilo-propionamide (DBNPA) has exhibited outstanding efficiency against in bio-films and against a broad spectrum of bacteria, fungus and yeasts.

Additionally, DBNPA series products are used in the short-term preservation of coatings and coating additives such as latex, starch and mineral slurries. It is a fast-acting/quick-kill biocide that is broad-spectrum, and does not contain or release formaldehyde
