Applications - A-zero-F Powder Additive
A-zero-F powder additive - "4-day Foam"
Long-duration foam from 2-hours to 4 days
Turns any Class A foam into an AR-AFFF with no fluorine
Patented granular powder sugar-based polymer is added to the water source (pumper tank, tender, brush truck, fixed or portable tank)
Solution can be stored for 18 months
So safe it is drinkable
Educt any Class A foam at 1% to combat any fuel fire
This was a proof-of-concept test.
Without A-zero-F, Class A foams dissolve on contact with polar solvents.
Was it feasible to add A-zero-F to a fire truck’s water tank and in 5 minutes extinguish a deep fuel polar solvent using only a Class A foam? See how it worked.
Real World Product Testing
Worst case scenario: Polar solvent fire - Class A foam - and a fog nozzle
A Class A foam would immediately dissolve on contact with a polar solvent. Patented A-zero-F stabilizes the foam bubble, making it resistant to polar solvents like Ethanol, IPA and Acetone and hydrocarbons like Heptane, Gasoline, MTBE, MTBE/Gasoline and Ethanol/Gasoline blends.
A-zero-F prevents hydrocarbon infiltration into the bubble which means long burnback resistance. All without the use of harmful and environmentally bio-persistent fluorochemicals. No need to choose which foam to use for different types of fuel hazards. One Additive – Any Foam – Any Fuel.™
A-zero-F was added to a fire truck's water tank and recirculated for 5 minutes.
Fire: 55 gallons Acetone, 51F
Class A foam: 1% Silv-ex
Application: Hale 1500 gpm Single Stage Pump through a low expansion fog nozzle, Task Force Tips B-BGH Automatic 100 psi on a 1" line.
50% Coverage 0:04
90% Control 0:27
98% Control 0:43
Tests show stable and cohesive foam 1 hour after application; self-sealing burnback and no flashovers when a section of foam is removed and lit.
A-zero-F is non-toxic, biodegradable, uses less water and is less expensive. The sugar-based formulation provides an environmentally safe alternative to current firefighting foam products.
