Chemguard 3% and 6% Standard Grade AFFF are synthetic aqueous film forming foam concentrates consisting of fluorocarbon surfactants, solvents and foam stabilizers. It is manufactured under strict quality control standards to ensure a reliable and dependable product. When mixed with water in the correct proportion, the mixture makes very fluid foam, which will flow rapidly over the fuel's surface. As the expanded foam mass begins draining, an aqueous film is formed that helps prevent the further release of any fuel vapors. The 3% SG AFFF or 6% SG-AFFF is recommended for use where fast knockdown, especially of a spill fire, is the primary requirement.
Chemguard 3% SG-AFFF is intended for use at a proportioning rate of 3% (3 parts SG-AFFF to 97 parts water) on Class B hydrocarbon based flammable or combustible liquids such as gasoline, diesel, kerosene, jet fuel, etc. Chemguard 3% SG-AFFF is NOT intended for use on any fuels, which are polar solvent/water miscible such as alcohols, ketones, esters, etc.
Chemguard 6% SG-AFFF is intended for use at a proportioning rate of 6% (6 parts SG-AFFF to 94 parts water) on Class B hydrocarbon based flammable or combustible liquids such as, gasoline, diesel, kerosene, jet fuel, etc. Chemguard 6% SG AFFF is NOT intended for use on any fuels, which are polar solvent/water miscible such as alcohols, ketones, esters, etc.
FEATURES
- Suitable for use with either fresh or salt water
- Excellent wetting characteristics when used in combating Class “A” fuel fires
- If inadvertently frozen, thawing will render product completely serviceable again

PERFORMANCE
To ensure the fire fighting performance required in today's market, Chemguard tests the 3% SG-AFFF and 6% SG-AFFF concentrates on a modified 50 square foot heptane fire at an application rate of 0.08 gpm/square foot.
FOAMING PROPERTIES
When 3% SG-AFFF or 6% SG-AFFF is mixed with water at the correct ratio, air-aspirating type discharge devices typically generate expansion ratios between 5-10 to 1. Non air-aspirating type devices will typically generate expansion ratios of between 2-4 to 1. Expansion ratios are dictated by the type of discharge device, flow rate and discharge pressure.
