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.
