Chemguard 3%-6% AR-AFFF C-361 is a specially formulated, aqueous film forming free flowing viscous foam concentrate. It forms a vapor suppressing aqueous film on hydrocarbon type fuels or a polymeric membrane on polar solvent/water miscible type fuels. It is intended for use at a proportioning rate of 3% (3 parts AR-AFFF concentrate to 97 parts water) on hydrocarbon fuels such as gasoline, kerosene, diesel etc. Chemguard 3%-6% AR-AFFF is intended for use at a 6% proportioning rate (6 parts AR-AFFF concentrate to 94 parts water) on polar solvent/water miscible fuels such as alcohols, ketones, esters, etc.
U. L. Listed, Foam Liquid Concentrates.
U. L. Canada Listed.
U. L. Listed for sub-surface injection applications.
Excellent wetting characteristics when used in combating Class “A” fuel fires.
Suitable for use with deluge and closed head foam water sprinkler systems.
Suitable for use with carbon steel, fiberglass, polyethylene or stainless steel. C361 is not compatible with galvanized pipe or fittings in an undiluted form.
Suitable for use with dry chemical extinguishing agents.
Suitable for use on hydrocarbon or polar solvent type fuels.
Suitable for use with both air-aspirating foam and standard water fog nozzles.
Suitable for use with fresh or salt water.
Fixed or portable in-line eductors.
In-line balanced pressure and pump pressure proportioning skid.
Bladder tank balanced pressure proportioning systems.
Around the pump proportioners.
Handline, air-aspirating nozzles with fixed eductor pickup tube.
Air-aspirating and non air-aspirating sprinkler heads or spray nozzles
Standard water fog nozzles for handlines and monitors
Air-aspirating foam nozzles
High back pressure foam makers for sub-surface base injection systems (Hydrocarbon type fuels only)
Foam makers for use with either Floating Roof storage tanks or Dike/Bund protection systems
Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3%-6% AR-AFFF is mixed with water at the correct ratio. Non-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.
Cannot be used in sub-surface applications with polar solvent type fuels.
TYPICAL PROPERTIES AT 77ºF (25ºC):
Appearance Off White Gel-Like Liquid.
Specific Gravity 1.016 g/ml.

ACETONE 0.14 gpm/ft²
METHYL ETHYL KEYTONE 0.13 gpm/ft²
ETHYL ACETATE 0.13 gpm/ft²
MTBE 0.15 gpm/ft²
ETHERS 0.15 gpm/ft²
Chemguard 3%-6% AR-AFFF is biodegradable, low in toxicity and can be treated in sewage treatment plants. Please refer to Chemguard Technical Bulletin regarding foam products and the environment.
If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range of 35°F to 120°F(2°C-49°C), a shelf life of between 20-25 years can be expected. If the AR-AFFF is to be stored in an atmospheric type foam concentrate storage tank, whether on mobile apparatus or stationary, limit the air space above the surface of the concentrate when possible and place a layer of quality mineral oil on the surface of the foam concentrate to minimize any effect from evaporation.Chemguard
