WANCIDE DA20

-Bactericide-

WANCIDE DA 20 is a solvent-based formulation of 2,2-dibromo-3-nitrilopropionamide. DA 20 is a biocide that easily hydrolyses under both acidic and alkaline conditions. In water it quickly kills microorganisms and then quickly degrades to ammonia and bromine ions. WANCIDE DA 20 is extremely efficient against bacteria and controls planktonic and sessile organisms. At higher concentrations it is also a fungicide. Algae control is seasonal and situational. DBNPA is suitable for bacterial slime cleanup where high levels of organics and biomass are present.

Product Benefits:

is highly efficient

can be used in a wide pH-range

is a quick-kill biocide

is environmentally friendly and biodegradable

has a good compatibility with other biocides and raw materials

is very cost effective

Applications and Use Levels:

WANCIDE DA 20 can be used for applications like

- water treatment

- pulp and paper

- slurry preservation

- reverse osmosis

- oil and gas

- metalworking fluids

WANCIDE DA 20 is also used as slime control on papermachines, and as a biocide in hydraulic fracturing wells. It is suitable for once-through cooling systems, because of its fast acting biocidal action (contact time often less than 1 hour).

WANCIDE DA 20 is compatible with other chemicals with the exception of mercaptobenzothiazole, ammonia or hydrogen sulfide. DBNPA should not be added in the presence of sodium bisulfite or other reducing agent residuals.
