CHEMGUARD 6% AFFF INTL AVIATION is a specially formulated synthetic aqueous film forming foam concentrate. This foam is intended for use at a proportioning rate of 6% (6 parts concentrate to 94 parts water) on Class B hydrocarbon type fuels such as gasoline, kerosene, diesel, etc. AFFF type concentrates are not intended for use on fuels, which are polar solvent/water miscible such as alcohols, ketones, esters, etc.

PERFORMANCE
Foaming Properties
When this product is proportioned correctly, aspirating type discharge devices can generate expansion ratios between 6-10 to 1. 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.
Compatibility
CHEMGUARD 6% AFFF INTL AVIATION. is compatible with any other comparable AFFF manufactured in accordance with and conforming to all performance requirements of CAN/ULC-S560 or any preceding version of this specification.
