Dowicil™ QK-20 is typically used in the clean-up and disinfection of process equipment tools and production tanks. The product is also used for the disinfection and decontamination of water based materials in the form of raw materials or finished products.

Dowicil™ QK-20 is ideal for reducing microbiological contamination of raw materials or finished products such as aqueous paints and coatings, polymers, inks, slurries, adhesives, latex and resin emulsions, sizing agents, caulk and sealants. It is also used in specialty industrial products including cleaning products, polishes, waxes, detergents and cleansers.

DOWICIL™ QK-20 Benefits


Instantaneous Antimicrobial Activity

Broad-spectrum activity against bacteria, fungi & yeast, 99.99% kill before rapid chemical degradation. Fast clean-up and disinfection for process equipment, tanks, filters, and felts. It also helps in the removal of biofilm buildup in piping systems.

Low Dosage Requirements 

Quickly dispersed upon introduction into your system with dosage rates between 0.05%-0.2000%, with thermal stability up to 63°C. It can be used effectively in combination with long-term preservatives to reduce the bio-burden on the long-term preservative.

Excellent Environmental Profile

Non-persistent, no bioaccumulation with rapid degradation to naturally occurring products (CO2, Ammonia & Bromide ion). It also does not contain or release formaldehyde.

Safe and Cost-Effective

Excellent compatibility and low-toxicity at recommended use levels provide industrial-strength answers to your sanitation needs.

Why DOWICIL™ QK-20 for process decontamination applications?

Dowicil™ QK-20 is based on 20% DBNPA (2,2-dibromo-3-nitrilopropionamide) that is featured with its quick and broad efficacy and short half-life. The short half-life is essential in clean-up and decontamination applications to ensure complete degradation of the active ingredient after the disinfection is complete without causing any concerns for disposal.

Dowicil™ QK-20 is also a non-oxidizing biocide which eliminates any corrosion potential or unwanted reactions with the process chemicals, such as typically observed polymer degradations when contacted with chlorine (bleach) or other oxidizing biocides.
