AR-AFFF

1. Description
DAFFCO AR AFFF 3/3 0°F is a synthetic, versatile AR-AFFF foam concentrate for fighting fires involving hydrocarbons and polar solvents (alcohols, ketones, ethers, esters, amines, etc.). It contains water-soluble polymers that give it pseudoplastic behavior. It includes fluorinated (C6 chain) and hydrocarbon-based surfactants that enable the formation of an aqueous film over most hydrocarbon fuels, reducing vapor release and oxygen contact.

2. Application
Suitable for use in low-expansion foam systems (hand nozzles, monitors, foam chambers, etc.) and with non-aspirating equipment (fog/jet nozzles, sprinklers, etc.). It can also be used with medium-expansion foam equipment. For polar solvents, gentle application is recommended.

3. Proportioning
The recommended proportioning ratio is 3% for extinguishing both hydrocarbon and polar solvent fires (alcohols, ketones, etc.). It is suitable for use with both fresh water and seawater. It can be proportioned using inline inductors, pump systems, bladder tanks, self-aspirating nozzles, etc.

4. Performance
The product enables rapid extinguishment and provides strong resistance to re-ignition with both portable and fixed equipment. It is UL-listed for hydrocarbon fires with Type III application at 0.10 gal/min·ft² and for alcohols with Type II application at 0.15 gal/min·ft².
