High efficiency Biocide 2.2-Dibromo-3-Nitrilopropion Amide DBNPA 99% For Industrial Water System
Basic Introduction:
Fast acting, broad spectrum biocide for treating raw materials,process water, and contaminated products and systems
Chemical name: 2.2-Dibromo-3-Nitrilopropion Amide(DBNPA)
CAS NO.:10222-01-2
DBNPA 99% is a fast-acting, non-oxiziding biocide. It has outstanding environmental properties because it is non-persistent and degrades to naturally-occurring products. DBNPA 99% provides efficient, cost-effective microbiological control at low use concentrations. the performance is similar to AQUCAR ™ DB 100 & AQUCAR ™DB 100 MUP.

Application Of DBNPA
It is a broad-spectrum and high-efficiency industrial fungicide used to prevent the growth of bacteria and algae in papermaking, industrial circulating cooling water, metalworking lubricants, pulp, wood, paint and plywood, as well as slime control agents. Widely used in paper mill pulp and circulating cooling water systems. As a broad-spectrum and high-efficiency biocide, it can quickly penetrate the cell membrane of microorganisms and act on a certain protein group to stop the normal redox of cells, thereby causing cell death. At the same time, its branches can selectively bromine or oxidize specific enzyme metabolites of microorganisms, ultimately leading to microbial death. This product has good peeling performance, no foam when used, liquid product and water can be dissolved at any ratio, low toxicity.
