T-STORM F783B

T-STORM F783B 3% AFFF 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.  It 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.  F783B 3% AFFF is not intended for use on polar solvent/water miscible fuels such as alcohols, ketones, esters, etc.

Features

Foam 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 77ºF / 25ºC

• Appearance Clear Slightly Yellow
• Specific Gravity = 1.020
• pH = 7.7
• Viscosity = 1.5 cps

Storage/Shelf Life

If kept in the original unopened and airtight factory supplied container and stored within the temperature range of 35ºF – 120ºF (2ºC – 49ºC) a shelf life of between 20-25 years can be expected. When stored in other than the manufacturers supplied container, please check with manufacturer for storage guidelines.
