BIOBAN-DB 20 Antimicrobial is a non-oxidizing and non-sensitizing sump side biocide that aggressively combats the contamination that can negatively impact metalworking operations and final product quality.
Compatible with all types of metalworking fluids, BIOBAN-DB 20 (2,2-dibromo-3-nitriloprompionaminde) is fast acting and can reduce a heavy bio burden within hours when a preservative can be added to the sump.
Effective at low levels, BIOBAN DB-20 combined with lower levels of existing preservatives can help reduce long-term preservative costs for end-users.

Applications:
Product-type 2: Disinfectants and algaecides not intended for direct application to humans or animals
Products used for the disinfection of surfaces, materials, equipment and furniture which are not used for direct contact with food or feeding stuffs.
Usage areas include, inter alia, swimming pools, aquariums, bathing and other waters; air conditioning systems; and walls and floors in private, public, and industrial areas and in other areas for professional activities.
Products used for disinfection of air, water not used for human or animal consumption, chemical toilets, waste water, hospital waste and soil.
Products used as algaecides for treatment of swimming pools, aquariums and other waters and for remedial treatment of construction materials.
Products used to be incorporated in textiles, tissues, masks, paints and other articles or materials with the purpose of producing treated articles with disinfecting properties.
Product-type 4: Food and feed area
Products used for the disinfection of equipment, containers, consumption utensils, surfaces or pipework associated with the production, transport, storage or consumption of food or feed (including drinking water) for humans and animals.
Products used to impregnate materials which may enter into contact with food.
Product-type 6: Preservatives for products during storage
Products used for the preservation of manufactured products, other than foodstuffs, feedingstuffs, cosmetics or medicinal products or medical devices by the control of microbial deterioration to ensure their shelf life.

Formulation/Applications Guidelines:
Solubility: Fully soluble in water and most polar and apolar organic solvents
Recommended use at pH: 7-10
Recommended storage temperature: Below 60°C/140°F
Efficacy:
Under normal conditions, BIOBAN DB 20 Antimicrobial is added to systems already containing microorganisms, so killing is extremely rapid and effective.
In contrast, slower-acting biocides may take 10 to 12 hours to achieve the antimicrobial results attained by BIOBAN DB 20 within 30 minutes of treatment.
In aqueous environments, BIOBAN DB 20 decomposes quickly.
The rapid antimicrobial activity of BIOBAN DB 20, combined with quick chemical breakdown, presents one of the most cost-effective ways of eliminating microbiological contamination with minimal effect on the final product.
BIOBAN DB 20 typically yields a 99.9 percent microbial kill before it degrades sufficiently to lose effectiveness.

Storage and Handling:
Temperature/decomposition rates
BIOBAN DB 20 Antimicrobial is effective and environmentally friendly as a biocide when properly administered.
However, the active component, dibromonitrilopropionamide (DBNPA), is temperature sensitive and will decompose exothermically (liberate heat) at elevated temperatures.
In addition, its decomposition rate increases with increasing temperature once the exothermic reaction begins.
If BIOBAN DB 20 is stored under adiabatic conditions, that is, where the heat cannot be removed or dissipated rapidly enough, the liquid temperature in the container will increase with decomposition, and this in turn will increase the decomposition rate.
To ensure safe handling and product quality, it is important to determine which storage systems are nearly adiabatic, and once identified, to monitor the temperature within those storage containers.
In relation to tank size, heat transfer from a bulk liquid decreases as its total volume increases.
When volume increases relative to a surface area, there is a “self-insulating” effect, allowing temperature to build up within the storage facility.
Product storage guidance
Product must be stored in closed, but vented, containers in an area with good general ventilation and out of direct sunlight to prevent build up of vapors over time
Product must not be stored above 35ºC
Avoid adiabatic conditions in pumps due to potential CO2 evolution and pressure generation/release
Aqueous solutions in plastic containers should not be left in direct sunlight to prevent photolysis of DBNPA
