Properties：It is a white to off-white crystalline powder. Melting point 125℃, soluble in ordinary organic solvents (such as Acetone, Benzene, Dimethylformamide, Ethanol,Polyethylene glycol, etc.). Slightly soluble in water (25℃, 100g water dissolved 1.5g). Its aqueous solution is stable under acidic condition, and easy to hydrolyze under alkaline condition. The dissolution rate can be greatly accelerated by increasing pH value, heating, UV light or fluorescence irradiation. Easy to be reduced agent, such as Hydrogen sulfide de-bromine into non-toxic Cyanoacetate amine, so that the sterilization rate is greatly reduced. Its half-life changed from 37.0h to 0.11h when its pH value changed from 6.7 to 9.7

Uses：DBNPA is a broad spectrum and efficient industrial fungicide, used to prevent bacteria and algae in paper making, industrial circulating cooling water, metal processing lubricating oil, pulp, wood, coating and plywood growth and reproduction, and can be used as mud control agent, widely used in paper mill pulp and circulating cooling water system. As a broad-spectrum and highly effective biocide, it can quickly penetrate the cell membrane of microorganisms and act as a certain protein group to stop the normal REDOX of cells, thus causing cell death. At the same time, its branches can selectively brominate or oxidize specific enzyme metabolites of microorganisms, resulting in microbial death. This product has good peeling performance, no foam when used, liquid products and water can be arbitrarily soluble, low toxicity.

Storage：Sealed and stored in a cool, dry and ventilated place.

Packing：25kg cardboard barrel
