Specification

Chemguard 3% x 6% AR-AFFF C363 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% x 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.

* Air-aspirating foam nozzles
* Foam makers for use with either Floating Roof storage tanks or Dike/ Bund protection systems

FOAMING PROPERTIES

Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3% x 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.

DESIGN INFORMATION

Cannot be used in sub-surface applications with polar solvent type fuels.

ENVIRONMENTAL IMPACT

Chemguard 3% x 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.

STORAGE

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.
