Product Description

Soluble C3H2Br2N2O DBNPA20 Water Treatment Chemicals

DBNPA series products are used in the short-term preservation of coatings and coating additives such as latex, starch and mineral slurries. DBNPA is a fast-acting/quick-kill biocide that is broad-spectrum, and does not contain or release formaldehyde


DBNPA is a highly effective and broad-spectrum industrial microbicides. It can prevent the bacteria and algae from growing in papermaking, industrial circulating cool water, metal processing oil, pulp, wood, paint and plywood. As an effective biocide, DBNPA can penetrate the membranes of microorganisms and affect a certain protein group to break the normal celluar redox, which causes the death of the cell. Meanwhile, its branch can selectively brominate or oxidize the metabolites of special enzyme, which is another way to cause microorganisms death. DBNPA is also widely used as slime control in pulp of paper mills and circulating cool water system.
