Description
Chemguard 3% AFFF Foam Concentrate
Chemguard 3% AFFF Foam Concentrate is a specially formulated, synthetic, aqueous film forming foam concentrate. A vapor suppressing aqueous film is formed by the foam solution draining from the expanded foam blanket.
The Chemguard 3% AFFF Foam Concentrate is intended for use at a proportioning rate of 3% (3 parts AFFF concentrate to 97 parts water) on Class B hydrocarbon type fuels such as gasoline, kerosene, diesel, etc. Chemguard 3% AFFF is not intended for use on fuels, which are polar solvent/water miscible such as alcohols, ketones, esters, etc.
Features:- U.L. Listed, Foam Liquid Concentrates
- U.L. recommended application rate on hydrocarbon type fuels is .10/gpm ft.
- U.L. Canada Listed
- FM Approved
- Performance to ICAO, Doc. # 9137, Part 1, Chapter 8, Level B verified
- Suitable for use with fresh or salt water
- Excellent wetting characteristics when used in combating Class A fuel fires
- Suitable for use with both aspirating foam and standard water fog nozzles
- Suitable for use with deluge or closed head foam water sprinkler systems
- If inadvertently frozen, thawing will render product completely serviceable again
- Suitable for use with carbon steel, fiberglass, polyethylene or stainless steel. Chemguard 3% AFFF is not compatible with galvanized pipe or fittings in an undiluted form.

Foaming Properties:
Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3% 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 devices, flow rate and discharge pressure.
Typical Properties at 77 degrees F (25 degrees C):Appearance: Clear Slightly Yellow Specific Gravity: 1.020 pH: 7.7 Viscosity: 1.5 cps
Environmental Impact:
Chemguard 3% 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.
Storage:
If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range of 35 degrees F - 120 degrees F (2 degrees C - 49 degrees C) a shelf life of between 20-25 years can be expected. When stored in other than the manufacturers supplied container, please check with Chemguard for storage guidelines.
