DBNPA CAS NO.10222-01-2

It is a broad spectrum and efficient industrial fungicide, used to prevent bacteria and algae in papermaking, industrial circulating cooling water, metal processing lubricants, pulp, wood, paint and plywood growth and reproduction, and can be used as mud control agent, widely used in paper mill pulp and circulating water system. As a broadspectrum 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.

Combat DBNPA

Description

DBNPA or 2,2-dibromo-3-nitrilopropionamide is a quick-kill biocide that easily hydrolyzes under both acidic and alkaline conditions. It is preferred for its instability in water as it quickly kills and then quickly degrades to form a number of products, depending on the conditions, including ammonia, bromide ions, dibromoacetonitrile, and dibromoacetic acid. DBNPA acts similar to the typical halogen biocides.

DBNPA is used in a wide variety of applications. Some examples are in papermaking as a preservative in paper coating and slurries. It is also used as slime control on papermachines, and as a biocide in hydraulic fracturing wells and in cooling water.

Active Ingredient

2,2-Dibromo-2-cyanoacetamide                 DBNPA（CAS: 10222-01-2)

Application

Combat DBNPA is recommended for the preservation of a wide range of applications including water-based adhesives, polymer emulsions, water based decorative paints, pigment slurries, metal working fluids, sealants and tile grouts, household products, printing inks, car care products and concrete add mixtures where protection against fungi and bacteria is required in the wet state.

It is effective against a wide range of common spoilage organisms including gram positive and gram-negative bacteria, yeast and fungi.

Use Level

Combat DBNPA should be evaluated in finished products at levels between 0.1 % and 0.25 % based on the total weight of the finished product.

The dosage required to adequately preserve the product depends on various factors including the nature and susceptibility of the product to microbial degradation, initial microbial content in the product, processing and storage conditions. It is recommended to conduct trials for new applications to access the performance of the biocide in the product in terms of stability, compatibility and biological effectiveness.

Storage and Shelf Life

Stable, but may be moisture sensitive. Incompatible with strong oxidizing agents. Stored in original containers under appropriate storage conditions (below 60℃, cool ventilated place). Shelf life is 24 months.

Packaging

PP bag or 25 kg paper barrel
