3Q-662 DBNPA-20

2.2-Dibromo-3-NitrilopropionAmide (DBNPA) 

3Q-662 DBNPA 20 is a broad-spectrum and high-efficiency industrial biocide.DBNPA antiseptic is used for water treatment agents, bactericidal algicide, papermaking and pharmaceutical intermediates to prevent bacteria andalgae in the field of papermaking, industrial circulating cooling water, lubricantsfor metal processing, Wood, paint and plywood in the growth and reproduction.It also could be used as slime control agent, widely used in paper mill pulpand circulating cooling water system.

As a broad-spectrum and highly effectivebiocide, 2.2-Dibromo-3-NitrilopropionAmide biocide can rapidly penetrate the cell membrane of microorganisms and acton certain protein groups to stop normal redox cells and cause cell death. Atthe same time, its branches can also selectively brominate or oxidize specificenzyme metabolites of microorganisms, eventually leading to the death ofmicroorganisms. DBNPA preservatives has a good peeling performance, no foam when used,liquid products and water can be any mutual miscibility, low toxicity.


Chemical Name

2.2-Dibromo-3-Nitrilopropion Amide (DBNPA)




Near colorless transparent liquid

Active content 


Range of Application:

Mainly used as bactericidal algaecide toprevent the growth of bacteria and algae in papermaking industry water,industrial cooling water, air-conditioning water, metal processing lubricants, emulsions,pulp, wood, plywood and coatings, and fibers.


The aqueous solution is relatively stableunder acidic conditions and is easily hydrolyzed under alkaline conditions.Raising the pH, heating, and irradiating with ultraviolet or fluorescent lightcan greatly increase the dissolution rate. Easy to be deoxidized by reducingagents such as hydrogen sulfide to become non-toxic amines of cyanoacetic acid,greatly reducing the bactericidal rate.

Package & Storage:

DBNPA 20 is packaged in 25kg/drum or 200kg/drum or IBC drum,and then wrapped in pallets to ensure the cargos are not damaged during transportation.
