Duro Kimia is the supplier of high quality, non-oxidizing DBNPA (2,2-dibromo-3-nitrilopropionamide) water treatment micro-biocide from DUPONT, IFF.

DBNPA has proven efficacy at low concentrations against bacteria, fungi, yeast, cyanobacteria (blue-green algae) and the true algae.

The 4 types of DBNPA:


Active Ingredient: 20%
Form: Liquid
Used as a RO membrane cleaning chemical to eliminate biological fouling in RO membranes and other pressure-driven membrane systems for industrial water production.
The Antimicrobial 7287 micro-biocide formulation is completely miscible with water upon dispersion at end use levels in the RO feed water system. The DBNPA molecule will function immediately upon introduction into the feed water; the rate of this activity is not affected by pH, and antimicrobial control is rapidly achieved if properly dosed.
When added to an RO system, DBNPA is easily rejected by the thin-film composite membrane layer and shows excellent compatibility with all materials of construction of the RO membrane module.


Active Ingredient: 20%
Form: Liquid
Quick-kill broad spectrum biocide that is ideal for reducing microbiological contamination in raw materials and products such as aqueous paints and coatings, polymers, slurries, adhesive, latex and resin emulsions, sizing, caulk, process water and specialty industrial products (inks, polishes, waxes, detergents and cleansers).
Dowicil QK-20 quickly and economically cleans up potential sources of contamination without requiring to shut down or delay production.
Can be used together with long-term preservatives.
