Tridol C6 ATF 3-6 LT

3x6% Alcohol Resistant Aqueous Film Forming Foam - Low Temperature (AR-AFFF-LT)

TridolC6 ATF 3-6 LT is a cost-effective Alcohol Resistant Aqueous Film-Forming Foam (AR-AFFF) concentrate for extinguishing and securing flammable hydrocarbon and polar solvent liquid fires.

TridolC6 ATF 3-6 LT is a unique combination of hydrocarbon and fluorocarbon surface active agents. It produces a vapour-sealing aqueous film that spreads rapidly over hydrocarbon surfaces to provide rapid control and extinguishment. On polar solvents an insoluble polymer membrane is formed which protects the foam blanket from the solvent.

  • Highly versatile and so eliminates the need to stock a variety of foam types.
  • Film-forming on hydrocarbons for fast flame knockdown and extinguishment.
  • Superior burnback resistance and post-fire security.
  • Foam blanket re-seals when ruptured by personnel or equipment.

Performance Approvals   

TridolC6 ATF 3-6 LT is independently tested and certified to EN1568:2008 Parts 3 & 4.

Environmental Impact    

TridolC6 ATF 3-6 LT is biodegradable and virtually non-toxic to aquatic organisms.

Applications                                     

TridolC6 ATF 3-6 LT is used in high risk situations where hydrocarbons (such as crude oil, gasoline, diesel fuel, aviation kerosene) and/or polar solvents (such as alcohols, ketones, esters, and ethers) are stored, processed, or transported.

Proportioning

TridolC6 ATF 3-6 LT is intended for use at 3% (3 parts concentrate to 97 parts of water) on hydrocarbons and 6% on polar solvents. 

TridolC6 ATF 3-6 LT is readily proportioned using conventional foam proportioning equipment such as portable and fixed foam proportioners at temperatures as low as -15°C (5°F).

TridolC6 ATF 3-6 LT can be used with air aspirating discharge devices such as low expansion branchpipes, monitors, top pourer sets, rimseal foam pourers, foam/water sprinklers, and base (sub-surface) injection systems at temperatures as low as -15°C (5°F).

TridolC6 ATF 3-6 LT can be used with non-aspirating discharge devices such as spray/fog branchpipes and nozzles, monitors, and spray/fog sprinklers.

Non-aspirated application is not recommended as the primary method of attack for major fires where a stable foam cover is essential.
