DBNPA Product Information

Overview

DBNPA, active ingredient chemical name is dibromocyanoaceta mide or dibromonitrilopropio namide. DBNPA is a quick kill biocide which quickly hydrolyzies under both acid and alkaline conditions. It is preferred for its instability in water as it quickly kills and then quickly degrades to ammonia and bromide ion.

Is DBNPA an oxidizer?

DBNPA is not an oxidizing biocide and it is not a bromine release biocide. DBNPA does act similar to the typical halogen biocides. The Liquid formulated DBNPA is an oxidizer, and the solid formulated DBNPA as a tablet is not an oxidizer.

Liquid (20% and 5%)

DBNPA liquid is widely used in pulp and paper water treatment applications. It is less widely used in cooling water due to its high cost relative to other agents. The liquid formulations of DBNPA contain DBNPA (white solid), sodium bromide, hydrobromic acid, hypobromous acid, tetraethylene glycol, and water. The liquid formulation is an oxidizing formulation and is similar to bleach and sodium bromide-bleach combinations. The liquid formulation is oxidizing because of the hypobromous acid in the formulation.

Slow release solid (40%)

DBNPA solid slow release form is very cost effective relative to isothiazolinones, the most expensive biocides and requires no metering equipment, special feeders, and one tablet can last up to 3 weeks!
