DBNPA

Duro Kimia is the supplier of high quality non-oxidizing DBNPA water treatment microbiocide from Dow Chemicals.
Also known as 2,2-dibromo-3-nitrilopropionamide.

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

We offer 4 different variants of DBNPA to suit customers’ various needs: –

Antimicrobial 7287
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 microbiocide 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.

Dowicil QK-20
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.

Sump Buddy
Active Ingredient: 40%
Form: Solid (Tablet)
A solid form of DBNPA in a time-release tablet.
Continuous delivery maintains an antimicrobial effective level for up to 3 weeks. Solid tablets are individually wrapped for your protection and ease of handling. Convenient and cost-effective treatment.
Used in: –

  • Industrial Cooling Water – Effectively inhibits growth of bacteria / algae / fungi on cooling pads, prolonging their useful life

  • Paper and Paperboard Manufacturing

  • Metal Working Fluids


Aqucar DB 100

Active Ingredient: 100%
Form: Solid (Powder)
Coupled with Smart Release® Technology, it has outstanding environmental properties because it is non-persistent and degrades to naturally-occurring products. It offers efficient, cost-effective microbiological control at low use
concentrations.
Used in industrial and commercial cooling water and air-washer systems.
