3X3% Alcohol-Resistant Aqueous Film Forming Foam Low Viscosity Concentrate

Phos-Chek® 3x3 AR-AFFF Low Viscosity (Alcohol-Resistant Aqueous Film Forming Foam) is a mixture of water, hydrocarbon surfactants, solvents, C6 fluorosurfactants and fluoropolymers. The product is a 3% concentrate proportioned solution for use on both hydrocarbon and polar solvent fires. Phos-Chek 3x3 AR-AFFF Low Viscosity foam is designed for rapid control and knockdown by producing a thin aqueous film on hydrocarbon fuels or a polymer membrane on polar solvent fuels that minimize vapor release, a foam blanket that separates the fuel from the air, and continual draining of water from the foam blanket provides cooling at the fuel surface.

Foam system designers are continually struggling with the limitations of equipment placement because of the higher viscosity of conventional alcohol resistant aqueous film forming foams and their inherent flow problems. Phos-Chek 3x3 AR-AFFF low viscosity (~10 cp) is ideally suited for foam systems with long distances between the foam storage tank and proportioning device.

Phos-Chek 3x3% AR-AFFF LOW VISCOSITY may be used with:

  • Low expansion foam equipment (nozzle, monitors, foam chambers, etc.)
  • Non-aspirating devices (water spray nozzles and standard sprinklers)
  • Medium expansion foam devices to fight fires involving Class B hydrocarbon fuel fires (crude oil, aviation fuels, diesel, etc.)
