Chemguard 3% x 3% AR-AFFF is a specially formulated, free flowing, viscous, aqueous film forming foam concentrate. It forms a vapor suppressing aqueous film on hydrocarbon type fuels or a polymeric membrane on polar solvent/water miscible type fuels.
Chemguard 3% x 3% AR-AFFF is a specially formulated, free flowing, viscous, aqueous film forming foam concentrate. It forms a vapor suppressing aqueous film on hydrocarbon type fuels or a polymeric membrane on polar solvent/water miscible type fuels. Chemguard 3% x 3% AR-AFFF is intended for use at a proportioning rate of 3% (3 parts AR-AFFF to 97 parts water) on hydrocarbon fuels such as gasoline, kerosene, diesel, etc., and on polar solvent fuels such as alcohols, ketones, esters, etc. Chemguard 3% x 3% AR-AFFF is specifically formulated for Topside, or Type II and Type III applications.
FOAMING PROPERTIES Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3% – 3% 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
TYPICAL PROPERTIES AT 77ºF (25ºC)
*Brookfield #4 Spindle at 30 rpm
DESIGN INFORMATION Cannot be used in sub-surface applications with polar solvent type fuels.
APPLICATION RATES Recommended application rate on hydrocarbon type fuels is 0.10 gpm/ft². On the following specific polar solvent type fuels these are the recommended minimum application rates.
Chemguard 3% – 3% 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.
STORAGE If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range of 35ºF – 120ºF, 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 airspace above the surface of the concentrate where possible and place a thin layer of quality mineral oil on the surface of the foam concentrate to minimize any effect from evaporation.
