Properties:
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. DBNPA is freely compatible with water by any proportion, no foam in use, with advantages in good slime-removing performance and low toxicity.

Usage:
DBNPA is widely used as disinfectant, microbicides, algicide, slime remover and mildewcide in circulating cool water system and oilfield water injection system. In papermaking industry, it is used to eliminate microorganism and alga and shuck off clay. DBNPA is also used as preservative for paint coating, waxwork, ink, detergent, surfactant, mud and resin, as bactericide and algicide in process water of machinery industry, air purifier system and municipal administration watescape.
When used as slime remover, the dosage of 30-50mg/L is preferred.
When used as bactericide in circulating cool water system, the dosage of 10-20mg/L is preferred.(as water retention capacity)
Safety:
No strong skin irritation. In case of contact, flush with water.
Package and storage:
Packed with cardboard drum or plastic woven bag. 25L/drum or 25kg/ bag, or as customers' requirement.
Storage for twelve months in shady and cool room with good ventilation.
