Tridol C6 Ultra 1-3

1x3% Alcohol Resistant Aqueous Film-Forming Foam Concentrate (AR-AFFF)

TridolC6 Ultra 1-3 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 Ultra 1-3 contains a unique combination of hydrocarbon and flurorocarbon 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.
  • Superior burnback resistance and post-fire security.
  • Foam blanket and film re-seals when ruptured by personnel or equipment.


Performance Approvals

TridolC6 Ultra 1-3 has been tested to the following International Standards:

  • Audited and approved to Underwriters Laboratories UL162 (7th Edition).
  • Passed Lastfire with excellent results in fresh and sea water.
  • Independently tested and certified to EN1568:2008 Part 3&4.

Environmental Impact

  • The C6 surfactants balance high performance and low environmental impact.
  • TridolC6 Ultra 1-3 demonstrates low aquatic toxicity.


  • TridolC6 Ultra 1-3 is used in high risk situations where hydrocarbons and/or polar solvents are stored, processed, or transported.
  • Typical applications include hydrocarbon storage tanks, process areas, warehouses, power stations, marine terminals and offshore platforms.


  • TridolC6 Ultra 1-3 is intended for use on hydrocarbons as 1% (1 part concentrate to 99 parts of water) low expansion foam or non-aspirated foam; and on polar solvents as 3% (3 parts concentrate to 97 parts of water) low expansion foam.
  • TridolC6 Ultra 1-3 can be used with air aspirating discharge devices and non-aspirating. Devices include low expansion branchpipes, monitors, top pourers, rimseal pourers, as well as water and foam sprinklers.
  • TridolC6 Ultra 1-3 is also suitable for base injection or sub-surface application systems. Non-aspirated, semi-aspirated and/or fully aspirated foam can be used in-line with a facility’s integrated risk management plan.

Integrity Angus Foams

Doing what’s right, rather than what’s convenient.

Angus Fire prides itself on the open and honest way in which we conduct our business throughout the world. Our foams are an extension of our ethical beliefs and we pride ourselves in being the responsible foam manufacturer, balancing high performance with minimal environmental impact. Our C6 foams contain no PFOA and no PFOS, in accordance with US EPA Stewardship Programme 2010/15 and EU Directive 2006/122/EC and amended Council Directive 76/769/EEC.

C6 Fluorosurfactants

These are the most effective agents currently available to tackle serious flammable liquid fires, providing firefighter safety and asset protection. Angus foams containing C6 surfactants utilise the very latest in firefighting foam technologies, developed and refined specifically to lower the environmental impact without reducing performance.
